Platform-independent
CheckDeletedObjectController
Platform: platform-independent.
Assembly: DevExpress.ExpressApp.v23.2.dll.

Platform-independent
ActionsCriteriaViewController
Platform: platform-independent.
Assembly: DevExpress.ExpressApp.v23.2.dll. Actions: none.
Disables and enables Actions depending on their ActionBase.TargetObjectsCriteria and ActionBase.TargetObjectsCriteriaMode property values.
DetailViewEditorActionController
Platform: platform-independent.
Assembly: DevExpress.ExpressApp.v23.2.dll.
Actions: none.
Activated for Detail Views. Collects the Actions of the current Detail View’s Items that implement the IActionSource interface and ensures that the Actions will be activated and can be executed. Actions are exposed by the IActionSource.Actions property.
DetailViewLinkController
Platform: platform-independent.
Assembly: DevExpress.ExpressApp.v23.2.dll.
Actions: none.
Activated for Detail Views. When a Detail View is invoked from a List View in a separate window, this Controller updates the List View if anything changes in the Detail View. For instance, when a Detail View’s object is replaced with another (for example, using the NextObject Action), the focused object in the List View changes. When an object is modified or deleted in a Detail View, the List View’s objects are updated as well. When an object is opened in a Detail View from a nested list view, all new objects created in this Detail View are automatically linked to the master object, which owns the collection bound to the nested List View. The DetailViewLinkController subscribes to the IObjectSpace.Committed event. In this event handler, an object matching the DetailView.CurrentObject is searched in the List View from which the current Detail View was opened. The found object is reloaded if the DetailView.CurrentObject is modified.
DialogController
Platform: platform-independent.
Assembly: DevExpress.ExpressApp.v23.2.dll.
Actions: DialogOK, DialogCancel.
Activated in pop-up windows invoked by the PopupWindowShowAction. Contains the DialogOK and DialogCancel Actions. You can add this Controller to a pop-up window when you create it using an Action’s ShowViewParameters object.

FillActionContainersController
Platform: platform-independent.
Assembly: DevExpress.ExpressApp.v23.2.dll.
Actions: none.
When a Template is created, all its Action Containers are created as well. Then, the FillActionContainers Controller uses the Application Model to determine Actions that are to be displayed within Action Containers. In particular, the ActionDesign | ActionToContainerMapping node provides this information. Then, this Controller calls the Action Container’s Register method for each Action to create the corresponding control. Action Containers create specific controls for each Action type.
See Also: IModelActionToContainerMapping | Actions | Action Containers
FocusDefaultDetailViewItemController
Platform: platform-independent.
Assembly: DevExpress.ExpressApp.v23.2.dll.

Extends the Application Model‘s DetailView nodes with the DefaultFocusedItem property that specifies the property editor initially focused when the root Detail View is displayed. Note that the Detail View displayed with the List View (see Display a Detail View with a List View) is not a root, so the DefaultFocusedItem property makes no sense in this case. The following platform-specific Controllers are derived from FocusDefaultDetailViewItemController: WinFocusDefaultDetailViewItemController and WebFocusDefaultDetailViewItemController.
