DockManager.VisibilityChanged Event

Fires after the visible state of any dock panel owned by the dock manager has been changed.

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

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type VisibilityChangedEventArgs containing data related to this event.

The following VisibilityChangedEventArgs properties provide information specific to this event.
Property Description
OldVisibility Gets the previous visible state of the panel.
Panel Gets the processed dock panel.
Visibility Gets the current visible state of the panel.

Expanded Remarks

A panel's visible state is specified by its DockPanel.Visibility property. Changing this property's value raises the VisibilityChanged event. This event is fired either when end-users close or show dock panels or when they enable or disable their auto hide functionality.

This event handler receives a parameter of the VisibilityChangedEventArgs type. It allows the previous and current visible states of the panel to be determined. The panel whose visible state has been changed is identified by the event parameter's DockPanelEventArgs.Panel property.
