Returns the number of items in the group.
An integer value specifying the number of items in the group.
The items of particular groups can be accessed on the client side by using the navbar’s client-side functionality. The GetItemCount method is used to determine the number of items maintained by the group’s NavBarGroup.Items collection. This method can be used together with the ASPxClientNavBarGroup.GetItem method when iterating through the group’s item list to determine its upper bound.
