You can also specify this property in code. Use the DefaultListViewOptions attribute to do this. Refer to the following topic for more information: Data Annotations in Data Model.

Important Notes

• Only WinForms applications, ASP.NET Web Forms applications with the ASPxGridListEditor, and ASP.NET Core Blazor applications with the DxGridListEditor support MasterDetailMode.ListViewAndDetailView mode.

• In ASP.NET Web Forms applications, the IModelListViewWeb.DetailRowMode option is similar to MasterDetailMode but it allows you to show a Detail View in a List View’s Detail Row.
• Blazor ListViews with a split layout display Dashboards in read-only mode.
• For the best performance, we do not recommend that you use IModelListViewWeb.DetailRowMode together with the ListViewAndDetailView mode.
• ASPxGridView and DxGridListEditor in ListViewAndDetailView mode ignore the AllowEdit and NewItemRowPosition options.
