Below code is for code behind:

protected void gviewProjectwisetask_ItemCommand(object source, GridCommandEventArgs e)

{

try

{

(e.CommandName.ToUpper() == "SELECT2")

{

GridDataItem gvr = (GridDataItem)((LinkButton)e.CommandSource).NamingContainer;

int RowIndex = gvr.ItemIndex;

if (RowIndex > -1)

{

int FileId = Convert.ToInt32(gviewProjectwisetask.MasterTableView.Items[RowIndex].Cells[12].Text);

string Str = FileId.ToString();

Response.Redirect(

"DownloadRedirect.aspx?ID=" + FileId);

}

catch (Exception ex)

{

}

}

Actual problem is when i click on linkbutton in gridview for downloading the file then progressbar showing perfectly here i have used Response.Redirect("DownloadRedirect.aspx?ID=" + FileId); after this line it is going to catch block here i want a solutions is that in catch block i want to disable the progressbar means i want to present aspx form in normal mode means without progressbar.

Just suggest me how it is possible.

Hi Linga,

Please review the below articles on how to download files and redirect to another page with RadAjax:

http://www.telerik.com/help/aspnet-ajax/ajxdownload.html

http://www.telerik.com/help/aspnet-ajax/ajxredirectingtoanotherpage.html

Additionally, I would suggest you to remove the ASP:UpdatePanel controls nested in the RadAjaxPanel and use only the RadAjaxPanel to ajaxify your page. Another option is you have two different RadAjaxPanel controls on the place of the ASP:UpdatePanels.

I hope this helps.
