Iam trying to export my RadGrid data, it works. But the excelfile has the ".xls" extension. Iam trying to replace the file extension with the next line of code:
Grid1.ExportSettings.Excel.FileExtension = "xlsx"
''I want to export to .xml extension to avoid the window for the untrusted resource of the excel ''document.
Grid1.ExportSettings.Excel.FileExtension = "xml"
So how can I edit the file extension of the export document?
