The MasterDetailMode property enables the split layout:

WinForms

ASP.NET Web Forms

ASP.NET Core Blazor

You can also specify this property in the DefaultListViewOptionsAttribute attribute (see Data Annotations in Data Model).

The value of this property is assigned to the Application Model‘s Application | Views | List View node’s IModelListView.MasterDetailMode property. You can change this property’s value using the Model Editor.

The default value of this property is the value that is assigned to the MasterDetailMode property of the Application Model’s List View node.

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.
