I resolve my problem with reflaction.

  var _itemList = typeof(GUITextControl).GetField("_itemList", BindingFlags.NonPublic | BindingFlags.Instance);
            ArrayList res = (ArrayList)_itemList.GetValue(chatControl);
 
            var _itemsPerPage = typeof(GUITextControl).GetField("_itemsPerPage", BindingFlags.NonPublic | BindingFlags.Instance);
            Int32 _itemsPerPageValue = (Int32)_itemsPerPage.GetValue(chatControl);
 
            int iPages = res.Count / _itemsPerPageValue;
            if (res.Count % _itemsPerPageValue != 0)
                iPages++;
            if (iPages > 1)
            {
                var _upDownControl = typeof(GUITextControl).GetField("_upDownControl", BindingFlags.NonPublic | BindingFlags.Instance);
                GUISpinControl val = (GUISpinControl)_upDownControl.GetValue(chatControl);
                int _upDownControlValue = val.Value;
 
                val.Value = iPages - 1;
                var onPageDown = typeof(GUITextControl).GetMethod("OnPageDown", BindingFlags.NonPublic | BindingFlags.Instance);
                onPageDown.Invoke(chatControl, null);
            }

may be its help some else.
