I have added an UltraWebGridExcelExporter to my application and a button control to call the export for a web grid
(eeGridExport.Export(uwgCollateral);)
When I run the app and click the button, I get the following error message:
"Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: OutputStream is not available when a custom TextWriter is used."
Infragistics35.WebUI.UltraWebGrid.ExcelExport.v8.2, Version=8.2.20082.2011, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb
Infragistics35.Excel.v8.2, Version=8.2.20082.2011, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb
Any ideas on what I need to do to fix this?
Thanks.
I have tried re-running the Update Toolbox Tool since installing the latest hotfix (some time ago), and this has not made a difference.
Does anybody have any ideas?? I really need to get this working.

After talking with Developer Support, it turns out that the button that calls the export cannot be inside of an ASP Update Panel. Moving the button outside of the Update Panel fixed the error.
has this been fixed in 10.3????
