        Dim setNickNameAction As New SimpleAction(Me, "SetNickName", PredefinedCategory.Edit)
        AddHandler setNickNameAction.Execute, AddressOf SetNickNameAction_Execute
    End Sub
    Private Sub SetNickNameAction_Execute(ByVal sender As Object, ByVal e As SimpleActionExecuteEventArgs)
        Dim currentObject As Contact = TryCast(View.CurrentObject, Contact)
        If currentObject IsNot Nothing Then
            currentObject.NickName = currentObject.FirstName
        End If
    End Sub
End Class

Use this property to access the focused object of the current List View’s ListView.Editor. If the focused object changes, the View.CurrentObjectChanged event is raised.

When a List View is displayed in the ListViewAndDetailView mode (IModelListView.MasterDetailMode), the object specified by the CurrentObject property is displayed in the accompanying Detail View.

For additional information, refer to the How to: Access Objects Selected in the Current View help topic.
