SilverLight：基础控件使用（5）-TreeView控件-基本使用_.NET_编程开发_程序员俱乐部

• 前台编辑
• 后台逐个添加
• 后台绑定数据源

<controls:TreeView Height="133" HorizontalAlignment="Left" Margin="29,23,0,0" 
                    Name="treeView1" VerticalAlignment="Top" Width="200">
    <controls:TreeViewItem Header="中国" IsExpanded="True">
        <controls:TreeViewItem Header="北京" />
        <controls:TreeViewItem Header="上海" IsSelected="True" />
        <controls:TreeViewItem Header="济南" />
    </controls:TreeViewItem>
    <controls:TreeViewItem Header="美国" />
    <controls:TreeViewItem Header="日本">
        <controls:TreeViewItem Header="大阪" />
        <controls:TreeViewItem Header="神户" />
    </controls:TreeViewItem>
</controls:TreeView>

Header, IsExpanded[是否展开], IsSelected[是否选中状态]

3,

//取值
string str1aHeader = ((TreeViewItem)treeView1.SelectedItem).Header.ToString();

<controls:TreeView Height="100" HorizontalAlignment="Left" Margin="34,152,0,0" 
                    Name="treeView2" VerticalAlignment="Top" Width="200" />

//A:TreeView2 逐个添加项
//第一层
TreeViewItem item1b = new TreeViewItem();
item1b.Header = "China";
item1b.IsExpanded = true;   //展开节点
#region 第二层，增加子节点
