ViewController.TargetObjectType Property

Specifies the type of objects that must be represented by a View to provide View Controller activation.

Namespace:DevExpress.ExpressApp
Assembly:DevExpress.ExpressApp.v17.1.dll

Expanded Syntax

Property value

Type: Type
A Type object that represent a persistent object's type.
The default is null.

Expanded Remarks

View Controllers are activated for both Windows and Frames. However, you can specify the type of objects represented by a View to provide a View Controller activation. For this purpose, specify the TargetObjectType property in code or the Designer.

To make a single View Controller available in Views of different business object types simultaneously, set the TargetObjectType property in code to an interface or their base class type, which is implemented or inherited by all these business types respectively. Alternatively, for the same task, you can specify several View identifiers via the TargetViewId property.

Note

The TargetObjectType property affects only ViewController's activation. Controller.FrameAssigned and other events that are irrelevant to the object type always fire.
