Assembly: System.Web (in System.Web.dll)
attributeName is a null reference (Nothing in Visual Basic).
The method is invoked in the get accessor of the Title property, the Description property, and any custom attributes that are defined in the Attributes property. The SiteMapProvider provider by which the SiteMapNode object is tracked must have its EnableLocalization property set to true for the method to be called. If the EnableLocalization is set to false, localization is not performed and the method is never called.
