Represents a method that will handle the TreeList.CalcNodeDragImageIndex event.

Namespace: DevExpress.XtraTreeList

Assembly: DevExpress.XtraTreeList.v18.1.dll

Declaration

C#

public delegate void CalcNodeDragImageIndexEventHandler(
    object sender,
    CalcNodeDragImageIndexEventArgs e
);

VB.NET

Public Delegate Sub CalcNodeDragImageIndexEventHandler(
    sender As Object,
    e As CalcNodeDragImageIndexEventArgs
)

Parameters

Name	Type	Description
sender	Object	The event source (typically, the TreeList control).
e	CalcNodeDragImageIndexEventArgs	A CalcNodeDragImageIndexEventArgs object that contains data related to the event.

Remarks

When you create a CalcNodeDragImageIndexEventHandler delegate, you identify the 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.
