以上是我的 XML。

在我的 .ASPX 页面中：

<asp:TreeView ID="TreeView1"  runat="server" 
    OnSelectedNodeChanged="TreeView1_SelectedNodeChanged1"  ImageSet="Arrows"       
    EnableTheming="true">
</asp:TreeView>  
<asp:Button ID="Button1" runat="server" Text="Submit" OnClick="Button1_Click" />

在我的代码隐藏中，我动态加载一个 xml 并构建一个树视图

protected void Button1_Click(object sender, EventArgs e)
   {
   doc.LoadXml("XmlFile");
      XmlNode node = doc.DocumentElement;
       TreeView1.Nodes.Clear();
       TreeView1.Nodes.Add(new TreeNode(doc.DocumentElement.Name));

       TreeNode tNode = new TreeNode();
       tNode = TreeView1.Nodes[0];

       Property obj = new Property();
       obj.AddChildNode(node, tNode);
       }

       In my Property.cs  (Class File)

       public void AddChildNode(XmlNode inXmlNode, TreeNode inTreeNode)
    {
        XmlNode xNode;
        TreeNode tNode;
        XmlNodeList nodeList;
        int i;

        // Loop through the XML nodes until the leaf is reached.
        // Add the nodes to the TreeView during the looping process.
        //if (inXmlNode.HasChildNodes)

        if (inXmlNode.ChildNodes.Count >= 1 && inXmlNode.ChildNodes[0].HasChildNodes)
        {

            nodeList = inXmlNode.ChildNodes;

            for (i = 0; i <= nodeList.Count - 1; i++)
            {

                xNode = inXmlNode.ChildNodes[i];


                inTreeNode.ChildNodes.Add(new TreeNode(xNode.Name));

                tNode = inTreeNode.ChildNodes[i];
                AddChildNode(xNode, tNode);

            }
        }
        else
        {
            if (inXmlNode.ChildNodes.Count > 1)
            {
                nodeList = inXmlNode.ChildNodes;

                for (i = 0; i <= nodeList.Count - 1; i++)
                {

                    xNode = inXmlNode.ChildNodes[i];


                    inTreeNode.ChildNodes.Add(new TreeNode(xNode.Name));

                    tNode = inTreeNode.ChildNodes[i];
                    AddChildNode(xNode, tNode);

                }
            }
            // Here you need to pull the data from the XmlNode based on the
            // type of node, whether attribute values are required, and so forth.
            else
            {

                if (inXmlNode.ChildNodes.Count == 0)
                {

                    inTreeNode.Text = (inXmlNode.Name).Trim();
                    inTreeNode.Target = inXmlNode.Attributes[0].Value;





                }
                else
                {
                    inTreeNode.Text = (inXmlNode.Name).Trim();
                    inTreeNode.Target = inXmlNode.Attributes[0].Value;
                    inTreeNode.Value = inXmlNode.ChildNodes[0].Value;
                }
            }
            //inTreeNode.Value = (inXmlNode.OuterXml).Trim();

        }
}

这里的问题是，当我运行我的代码并选择 Title 或 Subtile 节点时，焦点设置到该节点并触发 SelectIndexChanged 事件。但是，当我选择第一个孩子（Innerseries）时，它会完美运行。当第二个 Innerseries 孩子被选中，选择集中在那个节点上。但是，当我选择第三个孩子（Innereseries）时，焦点在第二个孩子上。所以，看起来当节点名称和值相同时，它选择了第一个节点.
