Occurs on the client side before a panel is closed, and allows you to cancel the action.
The PanelClosing event's data class is ASPxClientDockManagerCancelEventArgs. The following properties provide information specific to this event:
|cancel||Specifies whether to cancel the related action (for example, row edit, export). Inherited from ASPxClientCancelEventArgs.|
|panel||Gets the panel currently being processed.|
The ASPxDockManager’s client-side functionality provides the capability to respond to end-user manipulation of panels. Write a PanelClosing event handler to perform specific actions on the client side before a panel is closed.
The PanelClosing event provides an argument of the ASPxClientDockManagerCancelEventArgs type. You can use the event parameter’s properties to identify a panel (ASPxClientDockManagerCancelEventArgs.panel) currently being processed or cancel the action by setting the ASPxClientCancelEventArgs.cancel property to true
