Hello:

Is it possible upgrade from infragistics 10.3 to 11.1?

We need some features like AsyncExport with XamDataGrid that is not in our version. 

Do you know any other way to use AsyncExport without upgrade to new version of Infragistics? (I have been testing about this:

Dispatcher.CurrentDispatcher.Invoke(DispatcherPriority.Normal,new Action(delegate() {ExportExcel(); }));

But in the method ExportExcel:

....
DataPresenterExcelExporter exporter = new DataPresenterExcelExporter();
exporter.Export(presenterControl, fileName, WorkbookFormat.Excel2007); //This calling faults!

.....

Best Regards,
