剛開始接觸WPF，今天學習了下treeView控制元件，右擊新增事件。

看了很多網上大牛的東西，終究是搞懂了。

效果圖如下：

Xmal部分：

<TreeView Name="DataTreeView" Margin="1" Grid.Column="0" Grid.Row="4" PreviewMouseRightButtonDown="DataTreeView_PreviewMouseRightButtonDown">

程式碼部分：

#region TreeView 右擊事件t

        //右®¨°擊¡Â事º?件t

        privatevoid DataTreeView_PreviewMouseRightButtonDown(object

        {

            vartreeViewItem = VisualUpwardSeach<TreeViewItem>(e.OriginalSourceas DependencyObject)as TreeViewItem;

            //vartreeViewItem = sender as TreeViewItem;

            if(treeViewItem != null)

            {

                treeViewItem.ContextMenu =GetItemRightContextMenu();

                treeViewItem.Focus();

                e.Handled = true;

            }

        }

        static DependencyObject VisualUpwardSeach<T>(DependencyObject source)

        {

            while(source !=null&&source.GetType()!=typeof(T))

            {

                source = VisualTreeHelper

            }

            returnsource;

        }

        //右®¨°鍵¨¹上¦?下?文?菜?單Ì£¤

        ContextMenuGetItemRightContextMenu()

        {

            ContextMenumenu = new ContextMenu();

            MenuItemmenuItem = new MenuItem();

            menuItem.Header = "菜?單Ì£¤";

            menuItem.Click += new RoutedEventHandler(menuItem_Click);

            menu.Items.Add(menuItem);

            returnmenu;

        }

        voidmenuItem_Click(object sender, RoutedEventArgs e)

        {

           MessageBox.Show(“OK”);

        }

        #endregion
