CustomDrawObjectEventArgs<StyleObjectInfoArgs>Remarks
The TreeList.CustomDrawEmptyArea event fires before the control’s empty area is painted, allowing you to perform your own painting of the empty area or modify its appearance settings before it is painted using the default mechanism. The CustomDrawEmptyAreaEventArgs class inherits properties that provide the common information required to custom paint an element. It introduces the CustomDrawEmptyAreaEventArgs.BehindColumn property so you can identify the drawing area under the blank column header.
