Assembly:  System.Web (in System.Web.dll)

public string ImageUrl { get; set; }

Property Value

Type: System.String
The URL to a custom image that is displayed next to the node. The default is an empty string (""), which indicates that the ImageUrl property is not set.

ExceptionCondition
ArgumentNullException

The selected value is null.

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

If both the ImageUrl and ImageUrl properties are set, the image that is displayed is the one that is specified by the ImageUrl property.

The value of this property is stored in view state.
