Public ReadOnly Property Control As Object

Property Value

Type	Description
Object	An object which represents the current List Editor’s control.

Remarks

Use this property to customize the List Editor’s control. To do this, handle the Controller‘s ViewController.ViewControlsCreated event as shown below:

C#

using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Editors;
using DevExpress.ExpressApp.Win.Editors;
using DevExpress.XtraGrid;
// ...
public class MyViewController : ViewController<ListView> {
    protected override void OnViewControlsCreated() {
        base.OnViewControlsCreated();
        GridListEditor editor = (GridListEditor)View.Editor;
        GridControl grid = (GridControl)editor.Control;
    }
    // ...
}

VB.NET

Imports DevExpress.ExpressApp
Imports DevExpress.ExpressApp.Editors
Imports DevExpress.ExpressApp.Win.Editors
Imports DevExpress.XtraGrid
' ...
Public Class MyViewController
    Inherits ViewController(Of ListView)
      Protected Overrides Sub OnViewControlsCreated()
            MyBase.OnViewControlsCreated()
            Dim editor As GridListEditor = CType(View.Editor, GridListEditor)
            Dim grid As GridControl = CType(editor.Control, GridControl)
      End Sub
      ' ...
End Class

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

When deriving from the ListEditor class, a List Editor’s control customization should be performed in the CreateControlsCore method after the control is created (see ListEditor).
