I extended Jerry's solution to a more flexible and better performance solution in getting only desired controls and do not create intermediated Lists during recursive calls.

You can simply using like that to get the control:

var myControl = AllChildren(parent, c => c.Name == "xxx").FirstOrDefault();

For that you should include the following AllChildren funcion:

 private List AllChildren(DependencyObject parent, Func query,   List _List = null ) 
    {
        if (_List == null)
             _List = new List();

        for (int i = 0; i < VisualTreeHelper.GetChildrenCount(parent); i++)
        {
            var _Child = VisualTreeHelper.GetChild(parent, i);
            if (_Child is Control && query(_Child))
            {

                _List.Add(_Child as Control);
            }
            AllChildren(_Child, query, _List);
        }
        return _List;
    }
