Remarks

The TreeViewImageSet enumeration is used to represent the different sets of images that can be displayed in the TreeView control. You can select from a predefined set of images or create your own custom set by setting the TreeView.ImageSet property to the Custom value. When defining a custom set of images, you should specify an image for each of the properties in the following table. Otherwise, the default image for that property is used.

Property Description
CollapseImageUrl The URL to a custom image for the collapsed node indicator.
ExpandImageUrl The URL to a custom image for the expanded node indicator.
LineImagesFolder The URL to a folder that contains custom images for lines-connecting nodes.
NoExpandImageUrl The URL to a custom image for the non-expanding node indicator.
