Property Value

Type	Description
TreeList	A TreeList object that is the TreeListEditor‘s control.

Remarks

You can use this property to customize the List Editor’s control. Generally, the recommended place to do this is a custom Controller‘s ViewController.ViewControlsCreated event handler. The How to: Access the Grid Component in a List View article illustrates this approach.

If you need to execute a custom action after a List Editor’s control has been created, handle the ListEditor.ControlsCreated event.
