+# How to Generate the Two Level DetailsViewDataGrid with DataTable Collection in WinForms DataGrid?
+
+This sample illustrates how to generate the two level `DetailsViewDataGrid` with `DataTable` collection in [WinForms DataGrid](https://www.syncfusion.com/winforms-ui-controls/datagrid) (SfDataGrid).
+
+By default, the `DetailsView` will be added for single relation when the `AutoGenerateRelations` is enabled. To add multiple related tables in `DataGrid`, `AutoGenerateRelations` for each grid can be enabled through [SfDataGrid.AutoGeneratingRelations](https://help.syncfusion.com/cr/windowsforms/Syncfusion.WinForms.DataGrid.SfDataGrid.html#Syncfusion_WinForms_DataGrid_SfDataGrid_AutoGeneratingRelations) event.
+
+``` csharp
+//Event subscription
+this.sfDataGrid1.AutoGeneratingRelations += new Syncfusion.WinForms.DataGrid.Events.AutoGeneratingRelationsEventHandler(SfDataGrid1_AutoGeneratingRelations);
+
+//Event customization
+private void SfDataGrid1_AutoGeneratingRelations(object sender, Syncfusion.WinForms.DataGrid.Events.AutoGeneratingRelationsEventArgs e)
+{
+    //To enable AutoGenerateColumns for child grid.
+    e.GridViewDefinition.DataGrid.AutoGenerateRelations = true;
+}
+```
