Hi.
I have a problem here.I have one grid that i export to excel, XLS, this work fine,but when i try to export this to XLSX, it dont work.
This is the ERROR I get:UltraGridExcelExporter is ambiguous in the namespace Infragistics.Win.UltraWinGrid.ExcelExport

That error indicates that you have multiple versions of the same assembly referenced in your project.
Yes, that was the problem.
