Trigger ASP.NET Method from JavaScript Click Event

When working on an ASP.NET web page, you may encounter the need to execute an ASP method from a JavaScript click event.

To achieve this without resorting to Ajax or other techniques, you can employ the following steps:

Integrating JavaScript Event with ASP

1. Declare an Interface for the page class:

   public partial class Default : System.Web.UI.Page, IPostBackEventHandler

2. Add the RaisePostBackEvent method to the code file:

   public void RaisePostBackEvent(string eventArgument) { }

3. In the JavaScript onclick event, invoke the RaisePostBackEvent method:

   var pageId = '<%=  Page.ClientID %>';
   __doPostBack(pageId, argumentString);

This code initiates a postback to the ASP.NET page, allowing you to call the desired event and interact with the server-side logic from JavaScript.
