DockLayoutManager.BeforeItemAdded Event

Fires before an item is added to the current DockLayoutManager object.

Namespace:DevExpress.Xpf.Docking
Assembly:DevExpress.Xpf.Docking.v17.2.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type DevExpress.Xpf.Docking.Base.BeforeItemAddedEventArgs containing data related to this event.

Expanded Remarks

Handle the BeforeItemAdded event to specify actions to be performed immediately before an item (the BaseLayoutItem descendant) is added to the current DockLayoutManager. For instance, you might want an additional item validation to be performed before an item is added.
