I'm trying to export the grid in excel format with the code below and it's not being processed, I need something else installed, I do not have Excel, but LibreOffice installed on the machine.
Protected Sub ImageButton1_Click(sender As Object, e As ImageClickEventArgs)
RadGrid1.ExportSettings.Excel.Format = DirectCast([Enum].Parse(GetType(GridExcelExportFormat), "Xlsx"), GridExcelExportFormat)
RadGrid1.ExportSettings.IgnorePaging = False
RadGrid1.ExportSettings.ExportOnlyData = True
RadGrid1.ExportSettings.OpenInNewWindow = True
