Property Value

Type	Description
CompositeView	A CompositeView object representing the Detail View where the current View Item is created.

Remarks

Use this property to access the current View Item’s Detail View. The following code snippet demonstrates how to do this:

C#

using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Editors;
// ...
public class MyViewController : ViewController<DetailView> {
    protected override void OnActivated() {
        base.OnActivated();
        ViewItem viewItem = View.FindItem("FirstName");
        DetailView detailView = (DetailView)viewItem.View;
    }
    // ...
}

VB.NET

Imports DevExpress.ExpressApp
Imports DevExpress.ExpressApp.Editors
' ...
Public Class MyViewController
    Inherits ViewController(Of DetailView)
      Protected Overrides Sub OnActivated()
            MyBase.OnActivated()
            Dim viewItem As ViewItem = View.FindItem("FirstName")
            Dim detailView As DetailView = CType(viewItem.View, DetailView)
      End Sub
      ' ...
End Class

For instance, the ViewItem.Control‘s properties can be specified dependent on the View’s settings; or you can get the View’s View.ObjectSpace.

The View property is initialized in Detail Views only. If the current View Item is a Property Editor in an editable List View, is necessary to implement the IGridInplaceEdit interface in the underlying control to access the currently edited row. GridListEditor automatically assigns the IGridInplaceEdit.GridEditingObject property when the inplace editor is shown. In other List Editors, you should manually handle corresponding control events to set the GridEditingObject property when an editor control is being shown. Built-in Property Editors that support this mechanism are LookupPropertyEditor, ObjectPropertyEditor, PopupCriteriaPropertyEditor and ExpressionPropertyEditor.
