Public Event DockItemEndDocking As DockItemDockingEventHandler
The DockItemEndDocking event's data class is DockItemDockingEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Cancel | Gets or sets whether the current operation must be canceled. Inherited from ItemCancelEventArgs. |
| DockTarget | Gets the item to which the current item is being docked. |
| DockType | Gets how an item is being docked to another item. |
| DragPoint | Gets the point at which the item is being docked. The point is relative to the top left corner of the target item’s root parent. |
| Handled | Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. Inherited from RoutedEventArgs. |
| IsHiding | Gets whether the item is being docked over a zone used to set the item to the auto-hide state. |
| Item | Gets the currently processed item. Inherited from ItemEventArgs. |
| OriginalSource | Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. Inherited from RoutedEventArgs. |
| RoutedEvent | Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. Inherited from RoutedEventArgs. |
| Source | Gets or sets a reference to the object that raised the event. Inherited from RoutedEventArgs. |
The event data class exposes the following methods:
| Method | Description |
|---|---|
| InvokeEventHandler(Delegate, Object) | When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation. Inherited from RoutedEventArgs. |
| OnSetSource(Object) | When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes. Inherited from RoutedEventArgs. |
To prevent a panel from being docked where it’s dropped, set the Cancel parameter to true.
You can also set an item’s BaseLayoutItem.AllowDock property to false to prevent the item from being docked.
