'Declaration Protected Overridable ReadOnly Property ControlPrefix As String
protected virtual string ControlPrefix {get;}
This prefix will be rendered in front of CSS classes and other identifying labels to ensure their uniqueness for a given type of control. The timing when this prefix gets applied may be prior to the Init event firing, therefore it should not be used for differentiating control instances.
Inheritors should override this property and provide a short non-null string uniquely identifying the Type of their control. Failure to override ControlPrefix may cause some CSS class name collisions between different types of controls. For example, when a WebMonthView and a WebDayView are on the same page, a name conflict is possible between their DayStyle CSS classes (whose default CSS class name could be Day) unless they override ControlPrefix. If WebMonthView returned the prefix, "month", from its override then it's DayStyle would render with the CSS class name monthDay and no longer be in conflict with other controls on the page with a different type.
