CustomDrawEventArgs.DefaultDraw() Method

Performs default painting of an element.

Namespace: DevExpress.XtraTreeList

Assembly: DevExpress.XtraTreeList.v23.2.dll

NuGet Packages: DevExpress.Win.Navigation, DevExpress.Win.TreeList

Declaration

C#

public void DefaultDraw()

VB.NET

Public Sub DefaultDraw

Remarks

The DefaultDraw method can be useful if you need to draw custom information over the default element rendering. To do this, call the DefaultDraw method and then draw custom information using the methods provided by the CustomDrawEventArgs.Graphics and/or CustomDrawEventArgs.Appearance objects.

The DefaultDraw method automatically sets the CustomDrawEventArgs.Handled property to true to prevent additional default painting from being performed after a custom draw event handler has been completed.

The DefaultDraw method does nothing if the CustomDrawEventArgs.Handled property has already been set to true.
