{
    private C1XmlEditor _owner;
    private ToolStripMenuItem _btnUndo, _btnRedo;

    public MyContextMenuStrip(C1XmlEditor editor)
    {

        _owner = editor;

        // create menu items
        _btnUndo = (ToolStripMenuItem)Items.Add("Undo");
        _btnUndo.ShortcutKeys = Keys.Control | Keys.Z;
        _btnRedo = (ToolStripMenuItem)Items.Add("Redo");
        _btnRedo.ShortcutKeys = Keys.Control | Keys.Y;
    }

    protectedoverridevoid OnItemClicked(ToolStripItemClickedEventArgs e)
    {
        Close();

        if (e.ClickedItem == _btnUndo)
            _owner.Undo();
        elseif (e.ClickedItem == _btnRedo)
            _owner.Redo();

        _btnRedo.Enabled = _owner.CanCut;
        base.OnOpening(e);
