WF Events Handling - (ASP.NET Web Forms)

ASP.NET Web Forms are designed to handle various events and execute the appropriate code. In this page, we will discuss how to handle events in ASP.NET Web Forms.

Syntax

To handle an event in ASP.NET Web Forms, you must add the event name to the control's attribute, prefixed with the "on" keyword. For example, to handle the click event of a button control, add the "onclick" attribute to the button control.

<asp:Button ID="btnSubmit" runat="server" Text="Submit" onclick="btnSubmit_Click" />

Once the event is added to the control, you must create an event handler method in your code-behind file to handle the event.

protected void btnSubmit_Click(object sender, EventArgs e)
{
    // code to execute when button is clicked
}

Example

Here's an example of handling the click event of a button control in ASP.NET Web Forms:

<asp:Button ID="btnSubmit" runat="server" Text="Submit" onclick="btnSubmit_Click" />

protected void btnSubmit_Click(object sender, EventArgs e)
{
    // code to execute when button is clicked
    // for example, you could display a message:
    Response.Write("Form submitted successfully!");
}

Output

When the button is clicked, the event handler method is called, and the appropriate code is executed. In this example, the text "Form submitted successfully!" is displayed on the page.

Explanation

ASP.NET Web Forms provide a way to handle various events associated with controls on a page, such as button clicks, page loads, and text changes. By handling these events, you can execute the appropriate code and provide dynamic functionality in your web application.

Use

Event handling in ASP.NET Web Forms is useful for providing interactivity and user feedback in your web application. For example, you could handle the click event of a button to submit a form, or handle the text change event of a text box to perform live filtering of search results.
