XafApplication.OptimizedControllersCreation Property

Disables the instantiation of Controllers that will never be activated in nested List Views.

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

Expanded Syntax

Property value

Type: Boolean
true, if the optimized controllers creation is enabled; otherwise, false.

Expanded Remarks

When the OptimizedControllersCreation property is set to true, View Controllers that won't be activated due to ViewController.TargetViewType ViewController.TargetViewNesting ViewController.TargetObjectType or ViewController.TargetViewId restrictions are not created in nested List Views (within ListPropertyEditor). In applications created using the Solution Wizard version 17.1 or higher, the OptimizedControllersCreation property is set to true by default. It is recommended to set it to true in applications that are created in older versions. This can be done in the WinApplication and WebApplication descendant’s constructors:

Important

To avoid possible null reference exceptions in nested List Views, always ensure that the Frame.GetController<ControllerType> method result is not null when the OptimizedControllersCreation property is true.
