服务端  public static Control FindThePostBackControl(Control container)
        {
            // Note: this is an adapted eggheadcafe.com code.
            //
            Control control = null;            string ctrlname = HttpContext.Current.Request.Params["__EVENTTARGET"];
            if ( ctrlname != null && ctrlname != String.Empty )
            {
                string[] tokens = ctrlname.Split( new char[1] { ':' } );                if ( tokens != null && tokens.GetLength( 0 ) > 0 )
                {
                    ctrlname = tokens[( tokens.GetLength( 0 ) - 1 )];
                }                control = container.FindControl( ctrlname );
            }
            else
            {
                // If __EVENTTARGET is null, control is a button type and need to 
                // iterate over the form collection to find it
                //
                string ctrlStr = String.Empty;
                Control c = null;
                foreach ( string ctl in HttpContext.Current.Request.Form )
                {                    // Handle ImageButton controls
                    if ( ctl.EndsWith( ".x" ) || ctl.EndsWith( ".y" ) )
                    {
                        ctrlStr = ctl.Substring( 0 , ( ctl.Length - 2 ) );
                        c = container.FindControl( ctrlStr );
                    }
                    else
                    {
                        c = container.FindControl( ctl );
                    }                    if ( c is System.Web.UI.WebControls.Button || c is System.Web.UI.WebControls.ImageButton )
                    {
                        control = c;
                        break;
                    }
                }
            }            return control;
        }
