Not able to export to excel using IE8

Question

Hi

I am getting the below error when exporting data to excel from telerik grid(created a user control and using that) only in ie8 for https site.

I am using the below code for export functionality

     Response.ContentType = "text/csv";
     Response.AddHeader("content-disposition", "attachment; filename=filename.csv");
      Response.Write(csv);
     Response.End();

Note:cvs is a string builder which contains the data to export.

Please help me to resolve the issue.

Thanks for your replay. I have tried in that way also however the error existed. Please find below the code which resolved my issue. I am using telerikcontrol gridControl.Page.Response.ClearHeaders(); gridControl.Page.Response.Cache.SetCacheability(HttpCacheability.Private); gridControl.Page.Response.ContentType = text/csv;; gridControl.Page.Response.AppendHeader(content-disposition attachment; filename= + reportInfo.Description.Replace(  _) + .csv); gridControl.Page.Response.Write(csv); gridControl.Page.Response.End(); Note: gridControl(Name of telerik:RadGrid) csv is a string builder which contains the data to export

Have you checked Do not save encrypted pages to disk option in Tools-->Internet options -->Advanced-->security module ?? If it is checked then uncheck and try. Also if you are using cache anywhere in the page set to no-cache.
