ExportController Class
An abstract ViewController descendant, that contains the Export Action.
Namespace: DevExpress.ExpressApp.SystemModule
Assembly: DevExpress.ExpressApp.v25.2.dll
Declaration
Remarks
XAF activates the ExportController Controller in all Views. It provides the export functionality presented by the Export Action:
XAF activates this Action when the current List View’s List Editor implements the IExportable interface. To access this editor, use the ExportController.Exportable property. The editor’s IExportable.SupportedExportFormats property is used to populate the Action’s ChoiceActionBase.Items collection. If the SupportedExportFormats list is empty, the Action is not activated. For details on the Export Action, refer to the description of the ExportController.ExportAction property, which provides access to this Action.
ExportController allows you to change the Export Action’s behavior. Use the following events: ExportController.ExportActionItemsCreated and ExportController.Exported. Examples of handling these events are provided in the How to: Customize the Export Action Behavior topic. In addition, you can set another List Editor to be exported by the Action instead of the current List View’s List Editor. To do this, set it to the ExportController.Exportable property.
ExportController serves as the base for the WinForms-specific WinExportController. You usually do not inherit this class. Manual inheritance requires you to implement features that platform-specific descendants already provide. You can inherit the WinExportController class if you want to add custom functionality.
To determine whether the Controller is active, use the Controller.Active property (see How to: Detect a Lookup List View in Code). If you need to know the reason for its deactivation or activation at runtime, use the DiagnosticInfo Action.
Information about ExportController and its Export Action is available in the Application Model‘s ActionDesign node. To access it, use the Model Editor.
