I use that code but following error is occur:
Control 'ctl00_ContentPlaceHolder1_GridView1' of type 'GridView' must be placed inside a form tag with runat=server.

Check the tag of GridView1 in your .aspx file, and add runat="server" if it is not there.

you have to add these lines below your code
public override void VerifyRenderingInServerForm(Control control)
{
return;
}

now I suppose it will work --
