Hi Jeeva,

Try the accessing the Grid as shown below and see if it is working.

CS:

        RadGrid Grid = this.RadGrid1 as RadGrid;

Hi Shinu !

      Thx for u reply. i already tried this one also but results the same problem

[jeeva]

hi Shinu !
   Now i found the solution place the radgrid inside the content panel.

ContentPlaceHolder

cp = (ContentPlaceHolder)Page.Form.FindControl("cntBody");

 

 

Telerik.Web.UI.

RadGrid RadGrid1 = cp.FindControl("RadGrid1") as Telerik.Web.UI.RadGrid;
