page_load event firing twice in firefox with asp.net page or user control.

Technorati Tags: ASP.NET,C#.NET,ViewState

We are having a very large project in asp.net 3.5. During code review of project we have found that page_load event of one control is firing twice in the firefox browser. After doing some debugging i have found that it's due to one of the link button which is there in the control. I like to share you the same scenario with you all guys.

One of the developer from us has specified the link button click event  two times.  The first one in directly in the html with onclick  like following.

Code Snippet

1. <form id="form1" runat="server">
2.     <div>
3.         <asp:LinkButton ID="lnkButton" runat="server" onclick="lnkButton_Click"></asp:LinkButton>
4.     </div>
5.     </form>

And another in the initialize event he has also attached the event handler for the click event like following.

Code Snippet

1. protected override void OnInit(EventArgs e)
2.         {
3.             lnkButton.Click += new EventHandler(lnkButton_Click);    
4.             base.OnInit(e);
5.         }

So i have removed one of them from initialize event and now its calling page_load event only one time. This is also responsible for the failed to load ViewState error some time when you are adding controls dynamically.

Happy programming...

File upload control is not working with Update panel

We all are using update panel for the Ajax implementation in every site. Nowadays Ajax is almost there in each and every site. Update panel is working fine with the all other controls but when we use the file upload control then its not working fine. I have searched from lots for this and i have found one of simple solution from the Imran's blog. It is so simple and works very well. You just need to add the "multipart/form-data" attribute to the form.

Here is the link from which you can have all the information.

Review of Microsoft Visual Web Developer 2010 beta 2 express edition.

Microsoft visual studio express editions are light weight IDE provided free by Microsoft and also having almost all the functionality of its big brother Microsoft Visual Studio Professional edition except few. My pc is bit old now Its P4 and its having only 1gigs of ram so the express edition are the best suited for pc like mine. Microsoft has recently provided the beta 2 version of Microsoft new generation IDE called Visual Studio Twenty Ten(2010).

There are lots of changes from visual studio 2008 express edition and Microsoft Visual Studio 2010 Express edition. The first changes you will notice is the brand new splash screen and brand new colored logo for visual studio.

Another thing you will notice is the look and fill of IDE. It all looks like blue every where. Its is best suited for the Microsoft forthcoming operating system Microsoft Windows 7.

Another the difference is the create new project window which is bit stylish and having more options compare the to the visual studio 2008. There are two new things in new project dialog the first one the windows azure tools which is Microsoft's new steps towards the could computing(I will blog about this later one). and another thing is the Silver light application option. Now you can create three kind of application with the Microsoft SilverLight Application

1. Silverlight Application
2. Silverlight Navigation Application
3. Silverlight class library

Another difference is the default font for the IDE earlier it was Courier New and now its Consolas which is the next generation programming font. Which is more visual than the other fonts.

Another major difference is when you create a asp.net web application then its now having more default folders compare to visual studio 2008. There are site.master is also there and some default style sheet just like asp.net mvc applications. You will have default login control like asp.net mvc application. There are two more folder scripts and styles. In style you will have default style sheet for the application. Another folder is for the scripts which are having default JQuery as per earlier announcement Microsoft and JQuery will go together.

Another new things in Microsoft Visual Studio 2010 Visual Web Developer Expression edition is the Tool Setting menu which are having three setting by default.

1. Basic Settings
2. Code Optimized
3. Expert Settings.

All the three option will have different setting for solution explorer and all other stuff. Another new thing is visual web developer 2010 express edition having multi monitor support which is not there in earlier express editions.Visual web developer express also having windows presentation foundation code editor.

Another cool feature is the maximized windows in design view now you will have whole window is maximized in design view hiding other windows. So you visually look all the control more better. Another cool thing is the percentage dropdown through which you can set all screen by percentage as per your requirement.

There are lots of more features like Improved css compatibility,HTML and Javascript snippets,support for asp.net mvc application and support for multi target etc. I will blog about each feature in much more detail. T

If you still not downloaded the future version of visual studio express edition 2010 then you can download it from the following link.

Ahmedabad Community Tech Days- 3rd October-Rocks!!!

Last Saturday 3rd October. Ahmedabad .NET user group and Microsoft has organize the Microsoft Community Techdays. It was superb and well organized event thanks to Dhola Mahesh,Pinal Dave and Jacob Sebastian. We had four blasting session of Vinod Kumar, Pinal Dave, Jacob Sebastian and Prabhjot Singh Bakshi.

The first session was from vinod kumar on Microsoft Windows 7 and Microsoft Office 2010. Though he is sql server guy and very well known for his site. www.extremeexperts.com he has decided to take session for Microsoft Windows 7 and Microsoft Office 2010. The session was full of information and we have seen some of advance features of Microsoft upcoming operating system Windows 7 and new version of Microsoft Office 2010.

After that we went for the lunch and then followed by two sql server sessions from the Pinal Dave and Jascob Sebastian. Pinal Dave has taken session on SQL server Index and it was very useful session for any person related with software development. All the SQL Server index features is presented and he explains that where we should implement index and where we should not implement index for the better performance of queries through simples examples.

Then we have back to back session from Jacob Sebastian on the SQL Server errors . The session of awesome. I had never got such details explanation of the sql server error messages. He explained the best practices to write error handling code in sql server. Through it was session about error which every programmer hate it nobody was moved from his seat.

Then we had a tea break for 15 mins and after that Prabhjot Singh Bakshi has taken session on .NET Framework. The session was excellent and even advance concept was explain by simples examples. So overall it was great event and I enjoyed each and every session. Once again thanks for all the mentor of Ahmedabad .NET user group and Microsoft for organizing such events.

Store Page ViewState in Session with asp.net

As we all know we any web page on the internet is state less. We have to write our own mechanism to maintain state between httprequest and httpresponse. Asp.net has great features called viewstate to maintain state during page postback. It will store the element state in hidden variables with _VIEWSTATE. It will look like below.

If you are having large amount of controls then you will have larger viewstate on the page and it will increase your html kb as well as your performance. So to increase the performance of our application we need to store this viewstate in other place. ASP.NET 2.0 has nice new class called SessionPagePersister which will store the viewstate in the session. You just need to override the PageStatePersister property in your page and your viewstate will be on the page.

Here is the code.

Code Snippet

1. protected override PageStatePersister PageStatePersister
2. {
3. get
4. {
5. return new SessionPageStatePersister(this);
6. }
7. \

If you are having so many pages then you have to write that cod manually Instead of doing this you can use inheritance features of C#.NET to write the code in just one way and then inherit your page from that class. Following is the code for that. You can create a class called MyPage that class into all the pages here is the code for class MyPage .

Code Snippet

1. using System;
2. using System.Collections.Generic;
3. using System.Linq;
4. using System.Web;
5. using System.Web.UI;
6. 
   
7. namespace TestBlogApplication
8. {
9. public class MyPage:System.Web.UI.Page
10. {
11. protected override PageStatePersister PageStatePersister
12. {
13. get
14. {
15. return new SessionPageStatePersister(this);
16. }
17. }
18. 
    
19. }
20. \

and Then inherit the class in your page like following.

Code Snippet

1. using System;
2. using System.Collections.Generic;
3. using System.Linq;
4. using System.Web;
5. using System.Web.UI;
6. using System.Web.UI.WebControls;
7. 
   
8. namespace TestBlogApplication
9. {
10. public partial class Page1 : MyPage
11. {
12. protected void Page_Load(object sender, EventArgs e)
13. {
14. 
    
15. }
16. }
17. }
18. 
    

So that's it that way you can increase your application performance via maintaining the viewstate in session. Happy Codding..

Extend your existing classes with extension method in asp.net 3.5

In asp.net 3.5 there is one good features called extension method now you can extend your functionality without modifying existing classes. Extension method allow developers to add own functionality to any existing classes. You don't need to create subclass or don't need to recompile existing classes and still you can extend that class with extension methods. Let's create an example to extend existing string classes to convert a simple string to bold html string.

public static class MyExtensions
{
public static string ConvertToBold(this string mystring)
{
System.Text.StringBuilder myBoldString =new System.Text.StringBuilder(string.Empty);
myBoldString.Append("<strong>");
myBoldString.Append(mystring);
myBoldString.Append("</strong>");
return myBoldString.ToString();  
}
}

So now our extension method is ready. Following the sample code to use this extension method.

protected void Page_Load(object sender, EventArgs e)
{
string helloWorld = "Hello World";
Response.Write(helloWorld.ConvertToBold());
}

While running application you can out like below.

How to remove white spaces between tags and lines of html render by asp.net page

When asp.net page loaded in to browser there are lots of white spaces between tags and in tags that will increase your html kb. For example if your page around 300 kb then it will take 3 second to load on 100 kbps internet connection and in dial up connection it will still take time. So if you want to load your site fast on dial up internet connection then you need to decrease html kb as much you can and removing white spaces from the html will be good idea for that.

Following is the code for the page on which you want to remove white spaces from the html. It will decrease your html kb by 30 percentage.

private static readonly Regex REGEX_FOR_TAGS = new Regex(@">s+<", RegexOptions.Compiled);

private static readonly Regex REGEX_FOR_BREAKS = new Regex(@">[\s]*<",
RegexOptions.Compiled);
protected override void Render(HtmlTextWriter writer)
{
using (HtmlTextWriter writer = new HtmlTextWriter(new System.IO.StringWriter()))
{
base.Render(writer);
string htmlkb = writer.InnerWriter.ToString();
htmlkb = REGEX_FOR_TAGS.Replace(htmlkb, "> <");
htmlkb= REGEX_FOR_BREAKS .Replace(htmlkb, "><");
writer.Write(html.Trim());
}
}

Here in the above code there are two regular expression one for white space in tag and another for whitespace between tag and by just overriding the render event of event you can replace the whitespace.

Happy Coding...

Sending mail with secure service layer in asp.net 3.5/2.0

In earlier post i have mentioned that how to send the email using new System.Net.Smtpmail with asp.net 2.0 or higher version. Now lets learn how to send the mail with the secure service layer in the asp.net.

Security is the one of the most important requirement in today’s world as you are doing your business online you have keep secure from other wrong elements. Secure service layer add an

extra layer of security to your web application and sending mail with the SSL with tighten your security for mails. Your emails are more secure then ever and your valuable information will not going to wrong hands.

Here is the code from which we can send the email with the secure service layer. As i have mentioned in earlier post you need to to send email with authentication to use SSL. So you need to write following code. First you need to create message like following..

MailAddress fromAddress = new MailAddress("from@site.com","Nameofsendingperson");
message.From = @”fromAddress”;//here you can set address
message.To.Add("mailto:to@site.com%22%29;//");//
message.Subject = "Sending email with ssl";
message.CC.Add("cc@site.com");//ccing the same email to other email address
message.Bcc.Add(new MailAddress("bcc@site.com"));//here you can add bcc address
message.IsBodyHtml = true;//To determine email body is html or not
message.Body =@"Plain or HTML Text";

Then you have to sent message with following code.

System.Net.Mail.SmtpClient mailClient =
 new System.Net.Mail.SmtpClient("your smptp","ssl port");
//This object stores the authentication values
System.Net.NetworkCredential basicCrenntial = 
new System.Net.NetworkCredential("username", "password");
mailClient.Host = "Host";
mailClient.UseDefaultCredentials = false;
mailClient.Credentials = basicCrenntial;
// You have to add one other properties for SSL
mailClient.EnableSSL=true;
mailClient.Send(message);

Client Id of a control in ASP.NET 4.0.

Client Id is used to store the id of a server control in client side. ASP.NET Engine creates a very long client id to unique identify each element on the same page. If you are having so many inner controls hierarchy then asp.net will generate very long client id like “ctl00_Ctl001_ctl02_BM_Login_btnSave” here i i have used control name like ctrl00,ctr001,bm etc. If you are having long control name then it will more longer then this. This will increase html kilobytes for the pages and if you are having so many server controls in the page then it will take time to load in browser and will decrease performance of application . To overcome this problem we have to override existing asp.net controls like textbox,label etc and then you have override client id from server side with server side id. Now with asp.net 4.0 you can control client id generated by .net framework. In asp.net 4.0 there is one another property called ClientIdMode which will control the behavior of client id generated by .net framework. Like following.

<asp:Button ID="btnSave" runat="server" ClientIDMode="[Mode]" />

There are four types of different mode for ClientIdMode property.

1. Legacy- This is the same as in old version. It will generate client like like “ctl00_Ctl001_ctl02_BM_Login_btnSave” in old fashion.
   


2. Inherit-This is the default mode for every control . It will refer parent control to have its clientidmode. If you want to change it then you have to specify your client id mode for that control.
   


3. Static –This mode will put client id as static if you set server id like “btnSave” then it will generate the same ld like “btnSave”. So if you want to use this mode then you have to make sure that you are having all unique name in one pages. Otherwise it will be a mess for ids.
   


4. Predictable- This mode will used when the framework needs to ensure uniqueness of each control in particular way. The framework traverse from the control to parent controls and put hierarchy of parent control id with control id like ‘”ctrl0_btnsave” and for another btnsave its like “ctrl0_ctrl1_btnsave” etc.

Javascript is not working with update panel- Microsoft Ajax

As an asp.net developer we all must have to use update panel for the ajaxifying our application in today’s ajax world. No one likes postaback now. But when we add the some content with the java script under update panel then some times it’s stop working because of the update panel server side behavior. So what we should do? … Here is the trick. Normally we code java script in the asp.net page like following…

string alertScript = "javascript:alert('Alter From asp.net page')";
ClientScript.RegisterStartupScript(typeof(Page),"alertscript", alertScript);

Instead of this you should use.

string alertScript = "javascript: alert('This is aler from asp.net page')";
ScriptManager.RegisterStartupScript(this, this.GetType(), "alertScript",
                                alertScript,true);

This will work. Happy coding..

Page.MetaDescription and Page.MetaKeywords in asp.net 4.0

As i have in my earlier post Search Engine optimization is necessary for every sites otherwise site will not have more users and viewers. For search engine meta tag are very important one Search engine crawler get information from this meta tags. There lots of meta tag but most important meta tag are keyword and description. From keyword meta tag search engine crawler get information about keyword for which they list this site page and from the description tag they will get descriptive information about particular page.

ASP.NET 4.0 introduces support for this. Now you can create your own meta tag keyword and description with the help of Page.MetaDescription and Page.MetaKeywords. It will render as same description and keyword meta tags in simple HTML Page. For example if you write following in your page_load event.

protected void Page_Load(object sender, EventArgs e)
{
Page.MetaDescription = "This page contains information about asp.net 4.0";
Page.MetaKeywords = "ASP.NET 4.0,Search Engine Optimization";
}

It will render meta tag as following.

<meta name="description" content="This page contains information about asp.net 4.0" />
<meta name="keywords" content="asp.net 4.0, Search Engine Optimization" /> 

So now with asp.net 4.0 you can do your site search engine optimization very easily and you don’t have to write code for that.

Permanent redirection in asp.net 4.0

We all need search engine optimization in our sites. With web 2.0 site its necessary that our site is search engine friendly because if i write this blog but nobody comes to read my blog then what is the worth of it. So for every thing we need to have search engine optimization whether its a blog,site or any thing on web.

For Search Engine Optimization one of the most important thing is the permanent redirection with 301 headers. Now all you say what is 301 headers lets explore this thing in greater details.

301 Header in SEO:

Every dot net programmer does comes along Response.Redirect – It will redirect from one page to another page which causes 302 redirect. For search engine optimization 302 redirection is document is temporary moved from one location to another location so it will keep indexing the other document as well from which we have redirected. In 301 header it will stop the response from older page. So that search engine can index new location permanently.

We can achieve this functionality in asp.net 4.0 directly with permanent redirect method. Like following. It will create 301 headers for search engines/

Response.PermanentRedirect(“http://jalpesh.blogspot.com”);

With the help of this now you can redirect your 302 pages to 301 which will be more search engine friendly then the older one.

Partial Types, Class and Method in C#.NET 3.0/2.0

With C# 2.0 Microsoft has added partial keyword in C#. So what is partial keyword used for. Lets go through the partial keyword in greater detail.

First and foremost use of the partial keyword is the you can declare one class or method with more then one declaration and at the compilation time it will have one complete class.So now you can declare a class more then one file at the compile time it will be treated as one class.

For example this is one class

//first file Patial Class
public class partial PartialClass
{
   public void First()
   {
     //First function
   }
}

 Here is the another class

public class partial PartialClass
{
   public void Second()
   {
      // Logic...
   }
}

Now at the compile time it will be treat as single class like following.

public class PartialClass
{
   public void First()
   {
      // Logic...
   }
   public void Second()
   {
      // Logic...
   }
}

Same way you can use partial method it will treated as one method as compile time. Partial method will only available with C# 3.0. It will not be available to C# 2.0.

Practical Usage Of Partial Class:

There are lots of way where partial class is useful like many developer can work on same class via creating different files. There are lost of code generators available in market so you can extend the class functionality via marking them partial. Partial class can also be used for the manage code in separate files instead of creating large files. With C# 3.5 linq to sql designer uses this concept to split custom behaviors outside mapping class.

Sending email through System.Net.Mail.Smtpmail in asp.net 3.5/2.0

For any web application or website the sending email is a necessity for newsletter, invitation or reset password for everything we have to sent a mail to the people. So we need to see how we can send mail. In 1.1 we are sending emails with System.Web.Mail.SmtpMail which is now obsolete. Now in asp.net 2.0 or higher version there is a namespace called System.Net.Mail.Smtpmail in asp.net 3.5. With this namespace we can easily write a code to send mail within couple of minutes.

If you want to sent a mail first thing you need is smtpserver. Smtpserver is a server which will route and send mail to particular system. To use smtpserver we need to configure some settings in web.config following is the setting for the web.config.

<system.net>

    <mailsettings>

       <smtp deliveryMethod="Network">

         <network host="stmp server address or ip"

           port="Smtp port" defaultCredentials="true"/>

        </smtp>     

    </mailsettings>

</system.net>

Here you need to set the all the smtp configuration. This will be used by the smptclient by default. Here is the code for sending email in asp.net 3.5

SmtpClient smtpClient = new SmtpClient();

MailMessage message = new MailMessage();

try

{

   MailAddress fromAddress = new MailAddress("from@site.com","Nameofsendingperson");

   message.From = fromAddress;//here you can set address

   message.To.Add("to@site.com");//here you can add multiple to

   message.Subject = "Feedback";//subject of email

   message.CC.Add("cc@site.com");//ccing the same email to other email address

   message.Bcc.Add(new MailAddress("bcc@site.com"));//here you can add bcc address

   message.IsBodyHtml = false;//To determine email body is html or not

   message.Body =@"Plain or HTML Text";

   smtpClient.Send(message);

}

catch (Exception ex)

{

   //throw exception here you can write code to handle exception here

}

So from above simple code you can add send email to anybody
Adding Attachment to the email:If you want to attach some thing in the code then you need to write following code.

message.Attachments.Add(New System.Net.Mail.Attachment(Filename));

Here file name will the physical path along with the file name. You can attach multiple files with the mail.

Sending email with Authentication: If you want to sent a email with authentication then you have to write following code.

System.Net.Mail.SmtpClient mailClient = new System.Net.Mail.SmtpClient();

     //This object stores the authentication values

     System.Net.NetworkCredential basicCrenntial = 
          new System.Net.NetworkCredential("username", "password");

     mailClient.Host = "Host";

     mailClient.UseDefaultCredentials = false;

     mailClient.Credentials = basicCrenntial;

     mailClient.Send(message);

Happy Coding…

What’s new in asp.net 4.0 and .net Framework 4.0?

Microsoft.NET Framework 4.0 beta version is out now. Let’s see the what’s new in asp.net 4.0 for the developer purpose. There are lots of features are there. Some of them are following.

1) Extensible Output Caching:

ASP.NET 4.0 adds an extensibility to output caching now you can create your cache provider and will can use this provider for the caching. So now you can use your own data source for you caching.

2) AutoStart Webapplication

Before asp.net 4.0 you have to use application_load or application_start event for the extensive data processing before application pages loads. But now you can use auto start features of asp.net 4.0. A new scalability feature named auto-start that directly addresses this scenario is available when ASP.NET 4.0 runs on IIS 7.5 on Windows Server 2008 R2. The auto-start feature provides a controlled approach for starting up an application pool, initializing an ASP.NET application, and then accepting HTTP requests.

3) Permanently Redirecting a page

Before asp.net 4.0 you need to use response.redirect method to go to another page from new page. ASP.NET, developers have traditionally handled requests to old URLs by using by using the Response.Redirect method to forward a request to the new URL. However, the Redirect method issues an HTTP 302 Found (temporary redirect) response, which results in an extra HTTP round trip when users attempt to access the old URLs. Now permanent redirect will solve this. Its will also benefit for the Search Engine Optimization.

4) Compressed Session State:

ASP.NET 4.0 will have new option for session stored in sql server or in state service. You can compress your serialized session using GZip Compression

5) Page.Keywords and Page.Description Properties

In asp.net 4.0 now you can create dynamic keywords and description for a page using Page.Keywords and Page.Description Properties

6) Enabling View state for Individual Controls

In earlier version of the asp.net if you disable your parent control view state it will disable your child control view state but now with asp.net view state is not dependent on parent child control view state.

7) Routing in asp.net 4.0

Now you can have build in routing for your pages. You don’t have to write your url rewriting modules. It introduces a WebFormRouteHandler routing class which will take care of routing.

8) ClientID

In earlier asp.net version clientId is system generated and if you want to change you have to override it . ASP.NET by default generated a big string for the clientid which will increase your html kb. With asp.net you have small client id using different options Legacy,Static,Predictable,Inherit

There are several other features are also there like following

Live Data Binding

Observer pattern using JavaScript and JavaScript objects

ADONetServiceProxy Class

Formview Control Ehancements

Ajax Improvements in asp.net 4.0

I have just list some of the features you can have all the features available in asp.net 4.0 white paper from the following link.
