Example #1

            public ListBoxMultiUpdatePropertyNamesBehavior(System.Windows.Controls.ListBox listBox)
            {
                this._listBox = listBox;


                //存储原先的SelectedItem
                _previousSelectedItem = listBox.SelectedItem;

                listBox.SelectionChanged += listBox_SelectionChanged;

                //UnLoad时候，释放存储的资源，否则内存会泄露
                UIThread.BeginInvoke(new Action(() =>
                {
                    var container = _listBox.FindAncestor <TabbedMdiContainer>();
                    if (container != null)
                    {
                        container.SelectedWindow.Unloaded += SelectedWindow_Unloaded;
                    }
