Gets or sets a pattern view to represent the detail View.
A BaseView descendant that will be used to represent the detail's data.
Initially, the property contains the default pattern View for this relation retrieved from the GridControl.LevelTree tree. The View is retrieved based on the corresponding relation name. This name is specified automatically for relations created at the data source level. In other cases, you can handle the GridView.MasterRowGetRelationName event to specify the relation name that should be used. If the GridControl.LevelTree tree does not contain the View specified by this relation name, the DefaultView property will contain null (Nothing in Visual Basic) initially.
