ExpandStateChangingEventHandler Delegate

Represents a method that will handle the AccordionControl.ExpandStateChanging event.

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

Expanded Syntax

Parameters

sender
Type: Object
The AccordionControl that raises the event.
e
Type: ExpandStateChangingEventArgs
Data for the event.

Expanded Remarks

When creating a ExpandStateChangingEventHandler delegate, you identify the method that will handle the corresponding event. To associate an event with your event handler, add a delegate instance to this event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see Events and Delegates in MSDN.
