Property Value

The URL to a custom image that is displayed next to the node. The default value is an empty string (""), which indicates that this property is not set.

Use the ImageUrl property to specify a custom image for the current node in the TreeView control. This image is displayed next to the node and can be in any file format (.jpg, .gif, .bmp, and so on), as long as the client's browser supports that format.

The value of this property is stored in view state.
