Hi, I am using Infragistics35.WebUI.UltraWebGrid.ExcelExport.v11.1 for exporting to Excel from grid. It is working on my local machine with the default ASP.NET dev server. I use stream to push the excel to the browser. But when moved on production server, it is not working. The prod server uses IIS website. I dont understand why it is not working. Is there anything else to be done? please have a look the code..

In the button click event, i have written:

Infragistics.WebUI.UltraWebGrid.ExcelExport.UltraWebGridExcelExporter exporter = new UltraWebGridExcelExporter();

MemoryStream mstream = new MemoryStream();
exporter.Export(uwgReport, mstream);
exporter.Export(uwgReport, mstream);

byte[] byteArray = mstream.ToArray();

mstream.Flush();
mstream.Close();

Response.Clear();
Response.ClearContent();
Response.ClearHeaders();

Response.ContentType = "application/octet-stream";

Response.AddHeader("Content-Disposition", "attachment; filename=report.xls");

Response.BinaryWrite(byteArray);

Response.Flush();
Response.End();

Any help anybody could produce would highly be appreciated.

Thanks
