I have the next code, that it's executed after a postback inside a grid(www.tedit.net)

            ExcelFile efE = new ExcelFile(); 
            ExcelWorksheet wsE = efE.Worksheets.Add("email"); 
            Response.Clear(); 
            Response.ContentType = "application/vnd.ms-excel"
            Response.AddHeader("Content-Disposition""attachment; filename=" + e.Row["rowno"] + "_Email.xls"); 
            efE.SaveXls(Response.OutputStream); 
            Response.End(); 
 

I already see this next:
not-on-top-of-call-stack

My problem is when the code reaches Response.End it throws an exception error. In the link I mention, it doesnt say how to resolve the issue.

This is the error message:
Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack

Can you help please?

Hello,

I'm not sure what is the relation between RadControls and your scenario - could you please elaborate? I suppose you posted your question in a wrong forum.

Were you ever able to resolve this?  We are experiencing something similar exporting a pdf file.

thanks

Hello Mark,

The original poster was using third-party exporting library - is that so in your case?
If not, please provide more information about the issue.

We resolved it by just opening up a new window to a page that wasn't using Ajax.  It would be nice if we didn't have to do that, but we have a solution, so we are okay now.

thanks

Hello Mark,

Please isolate the problem in a simple demo and attach it to a formal support ticket. I will debug your code locally and will try to provide a workaround, specifically tailored for your scenario.
