Returns the number of groups in the navbar.
An integer value specifying the number of groups in the navbar.
By using the navbar's client-side functionality the navbar's groups on the client side can be accessed. The GetGroupCount method is used to determine the number of groups maintained by the navbar's ASPxNavBar.Groups collection. This method can be used together with the ASPxClientNavBar.GetGroup method when iterating through the group list to determine its upper bound.
