public class CheckItems : System.Collections.CollectionBase
Applications may interact with this type as it has been exposed through the Buttons collection of a button group; but are not required to construct instances of this collection directly.
When creating dynamic instances of Toolbar items, developers must add the item to it's eventual collection prior to setting property values on the object. Certain complex properties (such as the DefaultStyle) of an item may not properly persist in viewstate across postbacks when they are attached to a Toolbar item before addition to a collection. The act of adding an item to a collection that is in contact with the UltraWebToolbar server control is what triggers tracking of viewstate.
