+By default, [DetailsViewDataGrid](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.DataGrid.DetailsViewDataGrid.html) will be exported to Excel. You can customize its exporting operation by using `DataGridChildExcelExportingEventArgs`.
+
+## Excluding DetailsViewDataGrid while exporting
+You can exclude particular DetailsViewDataGrid while exporting, by using the DataGridChildExcelExportingEventArgs and `DataGridChildExcelExportingEventArgs.Cancel`.
+
+```csharp

+{
+    DataGridExcelExportingController excelExport = new DataGridExcelExportingController();
+    DataGridExcelExportingOption option = new DataGridExcelExportingOption();

+
+```csharp
