Event Data

The DockItemHidden event's data class is ItemEventArgs. The following properties provide information specific to this event:

Property Description
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.
Item Gets the currently processed item.
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 an item from being auto-hidden, disable the BaseLayoutItem.AllowHide option or handle the DockLayoutManager.DockItemHiding event.

Auto-hidden items can be accessed via the DockLayoutManager.AutoHideGroups collection. To make an item auto-hidden in code, use the DockController.Hide method provided by the DockLayoutManager.DockController object.
