Gets or sets the zero-based index of the currently selected item in a BulletedList control.
Assembly: System.Web (in System.Web.dll)
In the base class, ListControl, the SelectedIndex property returns a zero-based index of the currently selected item. The default is -1, which indicates that nothing is selected. The property is not applicable to the BulletedList control.
Note When you use the get accessor for the property, it always returns -1. An attempt to use the set accessor for the property raises a NotSupportedException.
This property is not bindable in visual designers, but is bindable at runtime. For more information, see BindableAttribute.
