        {
            get
            {
                if (Session["Grid"] != null)
                {
                    return (RadGrid)Session["Grid"];
                }
                else
                    return null;
            }
            set
            {
                Session["Grid"] = value;
            }
        }

        protected void imbExcel_Click(object sender, ImageClickEventArgs e)
        {
            try
            {
                if (ExportGrid.Columns.FindByUniqueName("TemplateSil") != null) ExportGrid.Columns.FindByUniqueName("TemplateSil").Visible = false;
            }
            catch { }
            try
            {
                if (ExportGrid.Columns.FindByUniqueName("TemplateDuzenle") != null) ExportGrid.Columns.FindByUniqueName("TemplateDuzenle").Visible = false;
            }
            catch { }
            try
            {
                if (ExportGrid.Columns.FindByUniqueName("TemplateDetay") != null) ExportGrid.Columns.FindByUniqueName("TemplateDetay").Visible = false;
            }
            catch { }

            if (rblAktarmaSekli.SelectedValue == "0")
                ExportGrid.ExportSettings.IgnorePaging = true;
            else
                ExportGrid.ExportSettings.IgnorePaging = false;

            ExportGrid.MasterTableView.ExportToExcel();
        }

 

What is problem?  By the way  throw exception when FindByUniqueName not found item also coltrol null value.
