DockLayoutManager.ShowingDockHints Event

Allows you to hide and disable individual dock hints.

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.ShowingDockHintsEventArgs containing data related to this event.

Expanded Remarks

The event fires when you drag a dock item over the dock UI. Dock hints are displayed while dragging, helping an end-user decide where to drop the item.

There are five Dock Guides displayed when dragging over panels: left, top, right, bottom and central:

Each Dock Guide consists of a number of Dock Hints. For instance, the central Dock Guide consists of five Dock Hints: Center, CenterBottom, CenterLeft, CenterRight and CenterTop. The left Dock Guide consists of two Dock Hints: SideLeft and AutoHideLeft, and so on.

The ShowingDockHints event allows you to disable individual Dock Guides and hide specific Dock Hints, according to your logic. This can be accomplished via the methods provided by the event's parameter: DisableAll, Disable, HideAll and Hide.

The following example shows how to handle the ShowingDockHints event:
