BeforeDragNodeEventHandler Delegate

Represents a method that will handle the TreeList.BeforeDragNode event of the TreeList class.

Namespace: DevExpress.XtraTreeList

Assembly: DevExpress.XtraTreeList.v24.2.dll

#Declaration

public delegate void BeforeDragNodeEventHandler(
    object sender,
    BeforeDragNodeEventArgs e
);

#Parameters

Name Type Description

The event source.

e BeforeDragNodeEventArgs

A BeforeDragNodeEventArgs class instance containing event data.

#Remarks

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