Remarks
Call the ExportToCsvAsync method to export grid data in CSV format. Note that only data cell values are exported - group rows, summaries, and cell style settings are ignored.
The method overloads allow you to write the result to a stream (the current overload) or to a file downloaded to a client machine (ExportToCsvAsync(String, GridCsvExportOptions)). The method accepts a GridCsvExportOptions object as a parameter. You can use this parameter to set up export settings.
For more information about data export in the Grid component, refer to the following topic: Export Data in Blazor Grid.
Important
Security Considerations
Exported data can contain executable content. To prevent possible security vulnerabilities, set the EncodeExecutableContent property to true to enclose potentially dangerous content in quotation marks prior to exporting it to the CSV format. To learn more, see the property description.
Large Data Limitations
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.
- If you export grouped data, you may see a different group breakdown in the resulting document. This happens because export depends on a 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.
