Some time ago I have written a blog post about Default focus and default button in ASP.NET. In that post I have explained how we can set default button for form. Recently I got email related to that post asking that how we can set or override default button on a page with master page.
In this page we will learn how we can override default button in master page. So what we are waiting for? Let’s start by creating a an asp.net empty application via File –> New Project –> ASP.NET Empty web application.
Once You are done with creating project it’s time to add a master page in solution via right click-> Add new Item.
Following is HTML code ASP.NET master page.
Now it’s time to add new content page with master page and selecting above master page.
Following is a code for content page.
Now I want to make default button as default button of form so whenever I press enter it will fire click event of default button. So to dynamically set / override default button on master page form I have to write following code on content page page_load event.
Now when you run and press enter in browser output will be as expected as follows.
That’s it. Hope you like it. Stay tuned for more..

Following is HTML code ASP.NET master page.
<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site1.master.cs"
Inherits="MasterPageDemo.Site1" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<asp:ContentPlaceHolder ID="head" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</div>
</form>
</body>
</html>
Now it’s time to add new content page with master page and selecting above master page.
Following is a code for content page.
<%@ Page Title="" Language="C#" MasterPageFile="~/Site1.Master" AutoEventWireup="true"
CodeBehind="Default.aspx.cs" Inherits="MasterPageDemo.Default" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<asp:TextBox runat="server" ID="Message"></asp:TextBox>
<ASP:Button runat="server" ID="DefaultButton"
OnClick="DefaultButton_Click" Text="Default"/>
<asp:Button runat="server" ID="AnotherButton"
OnClick="AnotherButton_Click" Text="Another"/>
</asp:Content>
Here I have added two buttons “Default Button” and “Another button” and a textbox. Now I want to make this “Default Button” default dynamically. Below code I have written for both button’s click event. It will only print in textbox which button is clicked.protected void DefaultButton_Click(object sender, EventArgs e)
{
Message.Text = "Default Button Clicked";
}
protected void AnotherButton_Click(object sender, EventArgs e)
{
Message.Text = "Another button clicked";
}
Now I want to make default button as default button of form so whenever I press enter it will fire click event of default button. So to dynamically set / override default button on master page form I have to write following code on content page page_load event.
protected void Page_Load(object sender, EventArgs e)
{
Form.DefaultButton = DefaultButton.UniqueID;
}
Now when you run and press enter in browser output will be as expected as follows.
That’s it. Hope you like it. Stay tuned for more..
