ViewController.TargetViewNesting Property

Specifies whether the View for which a View Controller is intended must be root, nested or any.

Namespace: DevExpress.ExpressApp

Assembly: DevExpress.ExpressApp.v18.2.dll

Declaration

C#

[DefaultValue(Nesting.Any)]
public Nesting TargetViewNesting { get; set; }

VB.NET

<DefaultValue(Nesting.Any)>
Public Property TargetViewNesting As Nesting

Property Value

Type	Default	Description
Nesting	**Any**	A Nesting enumeration value identifying a View kind.

Available values:

Name	Description
Any	An Action or a View Controller will be activated in Frames (Windows) with any Views.
Root	An Action or a View Controller will be activated in Frames (Windows) which contain root Views (see View.IsRoot).
Nested	An Action or a View Controller will be activated in Frames (Windows) which contain nested Views (the View.IsRoot property is set to false).

Remarks

View Controllers are activated for both Windows and Frames. However, you can specify the View kind to provide a View Controller activation within the Window or Frame via the TargetViewNesting property.

Note

The TargetViewNesting property affects only ViewController’s activation. Controller.FrameAssigned and other events that are irrelevant to the view nesting always fire.
