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.
The following code snippets (auto-collected from DevExpress Examples) contain references to the CreateController<ControllerType>() method.
Note
The algorithm used to collect these code examples remains a work in progress. Accordingly, the links and snippets below may produce inaccurate results. If you encounter an issue with code examples below, please use the feedback form on this page to report the issue.
var application = (XafApplication)sender;
e.Controllers.Add(application.CreateController<ManageUsersOnLogonController>());
e.Controllers.Add(application.CreateController<LogonActionCustomizationController>());
}
DialogController dialogController = Application.CreateController<DialogController>();
dialogController.Accepting += dialogController_Accepting;
e.ActionArguments.ShowViewParameters.TargetWindow = TargetWindow.NewModalWindow;
DialogController dialogCotnroller = Application.CreateController<DialogController>();
dialogCotnroller.Accepting += new EventHandler<DialogControllerAcceptingEventArgs>(dialogCotnroller_Accepting);
