How to Avoid Response.End() “Thread was being aborted” Exception during the Excel file download

Question

I tried to convert my dataset into excel and download that excel .I got my required excel file.But System.Threading.ThreadAbortException was raised every excel download. Ho

Answer 1

I recommend this solution :

1. Don't use response.End();

2. Declare this global var : bool isFileDownLoad;

3. Just after your (response.Write(sw.ToString());) set ==> isFileDownLoad = true;

4. Override your Render like :

   /// AEG : Very important to handle the thread aborted exception
   
   override protected void Render(HtmlTextWriter w)
   {
        if (!isFileDownLoad) base.Render(w);
   }
