Event Data

The BeginDocking event's data class is DevExpress.XtraTabbedMdi.FloatingCancelEventArgs.

Remarks

If the XtraTabbedMdiManager.FloatOnDrag option is enabled, a page can be made floating by dragging its tab header away from the XtraTabbedMdiManager‘s header region. The floating page can then be docked back onto the XtraTabbedMdiManager via drag-and-drop. When docking a floating page, the following events fire:

1. XtraTabbedMdiManager.BeginDocking - Fires before a floating page is docked to the XtraTabbedMdiManager. This event allows you to cancel the operation.
2. XtraTabbedMdiManager.EndDocking - Fires after the floating page has been docked to the XtraTabbedMdiManager.
