Finding which button clicked

If you want to know which button is being click befor the button click event there is a function which you will have to override.

override protected void RaisePostBackEvent(IPostBackEventHandler sourceControl, string eventArgument)

    {

        string s = ((WebControl)sourceControl).ID;

        Response.Write(s.ToString());

       

    }

This event is fired after page lod and before button click event.

Using this event one can find that due to which control post back occured.
