Event Data

The ShowingDockGuides event's data class is DevExpress.XtraBars.Docking2010.Views.ShowingDockGuidesEventArgs.


The figure below illustrates all hints displayed when a user drags a panel.


When a user drags a Document, only 5 central hints appear (hints #1, 2, 3, 4 and 5) since unlike panels, Documents cannot be docked anywhere but the DocumentManager.

All hints are stored inside guides. The are 5 global guides - a central guide that stores hints 1 to 9 (1 to 5 if a user drags a Document), and four side guides that store hints 10, 11, 12 and 13.

The ShowingDockGuidesEventArgs arguments class provides the Configuration property that exposes various public methods. These methods allow you to hide individual hints or guides that include multiple dock hints.
