When the user selects an item from the list, the SelectedValue is set to the Infragistics.Win.ValueListItem.DataValue of that Infragistics.Win.ValueListItem.
When the SelectValue changes, either by user action or in code, the UltraRadialMenu.ListToolSelectedValueChanged event will fire. To set the SelectedValue without firing the event, use the SetSelectedValue method and specify false for the 'fireEvents' parameter.
