ControlViewItem Class

A View Item that displays a specific unbound control in a UI.

Namespace: DevExpress.ExpressApp.Layout

Assembly: DevExpress.ExpressApp.v22.1.dll

Declaration

C#

public class ControlViewItem :
    ViewItem,
    IComplexViewItem

VB.NET

Public Class ControlViewItem
    Inherits ViewItem
    Implements IComplexViewItem

Remarks

In certain scenarios, you may need to add an unbound control to a Detail View. To do this, add a IModelControlDetailItem child node to the required Views | <DetailView> | Items node.

Set the child node’s IModelControlDetailItem.ControlTypeName property to the required control’s type. To handle the control’s events, implement a custom Controller that is activated for the View containing the ControlViewItem.

For an example of using the ControlViewItem, refer to How to: Create a Custom Control Detail Item topic.
