 ### Exporting DetailsView
 
+By default, [DetailsViewDataGrid](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.DataGrid.DetailsViewDataGrid.html) will not be exported to PDF. You can export `DetailsViewDataGrid` by setting `CanExportDetailsView` property as true.
+
+```csharp
+MemoryStream stream = new MemoryStream();
+DataGridPdfExportingController pdfExport = new DataGridPdfExportingController();
+DataGridPdfExportingOption option = new DataGridPdfExportingOption();
+option.CanExportDetailsView = true;
+var pdfDoc = pdfExport.ExportToPdf(this.dataGrid, option);
+pdfDoc.Save(stream);
+pdfDoc.Close(true);
+SaveService saveService = new();
+saveService.SaveAndView("ExportFeature.pdf", "application/pdf", stream);

+By default, only expanded DetailsViewDataGrids only will be exported to PDF document. If you want to export all the DetailsViewDataGrids, you need to set `CanExportAllDetails` as true.

+DataGridPdfExportingController pdfExport = new DataGridPdfExportingController();
+DataGridPdfExportingOption option = new DataGridPdfExportingOption();
+option.CanExportDetailsView = true;
+option.CanExportAllDetails = true;
