Call the ExportToXlsAsync method to export grid data in XLSX format. The method overloads allow you to write the result to a stream (the current overload) or to a file downloaded to a client machine (ExportToXlsxAsync(String, GridXlExportOptions)).

The method accepts a GridXlExportOptions object as a parameter. You can use this parameter to set up export settings.

Export Specifics and Limitations

• Content of templates is not exported, including detail grids.
• Custom summaries implemented in the CustomSummary grid event, are exported as plain text.
• Data columns anchored to the right edge become regular columns, while columns anchored to the Grid’s left edge remain frozen.
• Appearance settings applied by style settings or in the CustomizeElement event handler are not exported. You can handle the CustomizeCell event to customize grid elements’ appearance in the the exported document.

If the grid is bound to a GridDevExtremeDataSource object, the following limitations apply:

• If you want to export selected rows only, specify the KeyFieldName property.
• Grouped data, and filtered and sorted selected rows may differ in the resulting document. This happens because export depends on database collation. For example, the same string with different capitalization may form multiple groups in the exported document. The Grid component puts such values into a single group.
