Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

Declaration

public bool Cancel { get; set; }

Property Value

Type	Description
Boolean	true to cancel the row export; false to export the row.

Remarks

The RowExporting action is called before a row is exported and allows you to cancel the action. Write the action handler to filter the exported data. Set the Cancel property to true to prevent the export of the processed row.

async Task ExportXlsx_Click() {
    await MyTreeList.ExportToXlsxAsync("ExportResult", new TreeListXlExportOptions() {
        RowExporting = RowExporting
    });
}
void RowExporting(TreeListRowExportingEventArgs e) {
    // Exports rows whose due date is earlier than January 1, 2018
    if ((DateTime)e.GetRowValue("DueDate") > new DateTime(2018, 1, 1)) {
        e.Cancel = true;
    }
}
