   // perform some operations on a group here
   //...
   for (int j = 0; j < currGroup.ItemLinks.Count; j++) {
      NavBarItemLink currLink = currGroup.ItemLinks[j];
      // perform some operations on a link here
      //...
   }
}

Imports DevExpress.XtraNavBar
' ...
Dim I, J As Integer
For I = 0 To NavBarControl1.Groups.Count - 1
