Assembly: System.Web (in System.Web.dll)
The property is used primarily by control developers in custom controls that derive from the RadioButtonList class.
If there are no items set in the RadioButtonList control, the property is zero. If there are items set in the RadioButtonList control, the property is the same as the ListItemCollection.Count property on the Items collection.
