Remarks
The ExportAction is a SingleChoiceAction Action that allows end-users to export data displayed in the current List View to various formats. The Action is active when the current List View’s ListView.Editor supports the IExportable interface and the editor’s control supports the IPrintable interface. The target formats, that the Action can export, are determined by the List Editor to be exported. So, the Action’s ChoiceActionBase.Items list is filled based on the List Editor’s IExportable.SupportedExportFormats property. To customize the Items list after it has been populated, handle the ExportController.ExportActionItemsCreated event.

To determine why the Export Action is currently deactivated or disabled, use the DiagnosticInfo Action. If you need to change the Action’s “active” or “enabled” state in code, use its ActionBase.Active or ActionBase.Enabled property, respectively.
Information on the Export Action is available in the Application Model‘s ActionDesign node. To access it, use the Model Editor.
