Public Event DocumentClosing As DocumentCancelEventHandler
The DocumentClosing event's data class is DocumentCancelEventArgs. The following properties provide information specific to this event:
|Cancel||Gets or sets a value indicating whether the event should be canceled. Inherited from CancelEventArgs.|
|Document||The Document related to the current event.|
You can handle the DocumentClosing event to prevent a document from being closed. This can be accomplished by setting the event's Cancel parameter to true.
When a document is closed, it is destroyed. After the document has been closed, the BaseView.DocumentClosed event fires. This event serves for notifications only.
To temporarily hide a document, use the BaseView.RemoveDocument or IBaseViewController.RemoveDocument method. The IBaseViewController.RemoveDocument method is accessible via the View's Controller property (TabbedView.Controller or NativeMdiView.Controller).
