If you are asking how to export a grid to an Excel file but not include all the columns in the file, in the events of the ExcelExporter you could either remove the columns completely from the grid OR you can hide them.

Private Sub  ExportGrid()

UltraWebGridExcelExporter1.Export(

Me.grdExport)

UltraWebGridExcelExprter1.DownloadName = ("Whatever you want to name it")

End Sub 'Exports grid 

I think this is what you are asking about in the early hours of the morning.  Don't forget to add a the UltraWebGridExcelExporter to your design.
