Public Event ClosingPanel As DockPanelCancelEventHandler
The ClosingPanel event's data class is DockPanelCancelEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Cancel | Gets or sets whether the operation performed on the processed panel should be cancelled. |
| Panel | Gets the processed dock panel. Inherited from DockPanelEventArgs. |
When any panel is closing the panel’s ClosingPanel and dock manager’s DockManager.ClosingPanel events are fired. Either of these events can be handled to prevent a specific panel from being closed or to perform specific actions on the panel before it is closed.
See the DockManager.ClosingPanel topic description for more information.
