之前wpf项目用到listbox右键编辑的功能，想到当时找资料不好找，特地将自己的结果拿出来与大家分享，探讨。

首先添加一个listbox。

  <ListBox x:Name="List_lianxiren" MouseDown="List_lianxiren_MouseDown"  SelectionMode="Extended" Margin="15,0" />

后台代码：

TextBox txtNode = new TextBox();

ListBoxItem selectNode = null;

string olddata;

//绑定数据到listboxitem；其中array不仅仅局限于数组，此处用数组举例而已；

public void BindingData()

{

     　　 ListBoxItem tvi;

            MenuItem menuitem;

            ContextMenu contextmenu;

            for (int i = 0; i < Array.Length; i++)

            {

                tvi = new ListBoxItem();

                tvi.Content = Array[i].Owner;

                tvi.Name = "_" + Array[i].id.ToString();

                contextmenu = new System.Windows.Controls.ContextMenu();

                menuitem = new MenuItem();

                menuitem.Header = "编辑";

                menuitem.Click += new RoutedEventHandler(menuitem_Click);

                contextmenu.Items.Add(menuitem);

                contextmenu.Width = 130;

                tvi.ContextMenu = contextmenu;

                tvi.GotFocus += new RoutedEventHandler(tvi_GotFocus);

                List_lianxiren.Items.Add(tvi);

            }

}

//编辑框失去焦点方式一

private void List_lianxiren_MouseDown(object sender, MouseButtonEventArgs e)

{ EditNameSaveToServer(); }

//点击编辑按钮，变为编辑框

 void menuitem_Click(object sender, RoutedEventArgs e)

{

            selectNode = List_lianxiren.SelectedItem as ListBoxItem;

            txtNode = new TextBox();

            if (!(selectNode.Content is TextBox))

            {

                olddata= selectNode.Content.ToString();

                txtNode.Text = selectNode.Content.ToString();

                txtNode.MaxLength = 20;

                txtNode.Focus();

                selectNode.Content = txtNode;

            }

}

//编辑框失去焦点方式二

void tvi_GotFocus(object sender, RoutedEventArgs e)

{

            if (selectNode == null)

            {

                selectNode = sender as ListBoxItem;

                txtNode = new TextBox();

                txtNode.Text = selectNode.Content.ToString();

                olddata= selectNode.Content.ToString();

            }

            EditNameSaveToServer();

}

//编辑框失去焦点后的处理事件，将数据保存到服务器什么的处理。

private void EditNameSaveToServer()

{

            if (!string.IsNullOrWhiteSpace(txtNode.Text))

            {

                selectNode.Content = txtNode.Text;

            }

            else

            {

                selectNode.Content = olddata;

            }

}
