Assembly: DevExpress.ExpressApp.v24.1.dll

public virtual ControllerType CreateController<ControllerType>()
    where ControllerType : Controller, new()

Type Parameters



Type Description

A Controller of the specified type.


When you implement a PopupWindowShowAction, you may need to provide a custom Dialog Controller for the Action’s pop-up Window. Use the CreateController<ControllerType> method to create this custom Dialog Controller:

private void MyPopupWindowShowAction_OnCustomizePopupWindowParams(Object sender,
      CustomizePopupWindowParamsEventArgs e) {
   e.DialogController = Application.CreateController<MyDialogController>();

This method creates a Controller of the specified type. If a Controller of the same type already exists, the Controller.Actions of the found Controller serve as a source for the ActionBase.Model property of the new Controller’s Actions.
