Debug.Assert(control != null, "control should not be null");
Debug.Assert(!String.IsNullOrEmpty(controlID), "controlID should not be empty");
Control currentContainer = control;
Control foundControl = null;
if (control == control.Page) {
// If we get to the Page itself while we're walking up the
// hierarchy, just return whatever item we find (if anything)
// since we can't walk any higher.
