您好，除了鼠标单击（单击或双击）和键盘导航显示“所选节点未突出显示”外，一切正常。

填充树节点的代码隐藏是
protected void Page_Load(object sender, EventArgs e)
{
Ext.Net.TreeNode root = this.CreateNode(SiteMap.RootNode);
root.Draggable = false;
root.Expanded = true;
FolderTree.Root.Add(root);
FolderTree.ExpandAll();
}
/// <summary>
/// Creates nodes from sitemap data
/// </summary>
/// <param name="siteMapNode">Pass the root node of Web.sitemap</param>
/// <returns></returns>
private Ext.Net.TreeNode CreateNode(SiteMapNode siteMapNode)
{
Ext.Net.TreeNode treeNode = new Ext.Net.TreeNode();
treeNode.NodeID = siteMapNode.Key;
treeNode.Text = siteMapNode.Title;
treeNode.Qtip = siteMapNode.Description;
//treeNode.Href = siteMapNode.Url;
treeNode.Icon = this.GetIcon(siteMapNode["menuId"].ToString(new CultureInfo("en-Us")));
string iconCls = GetIconCls(treeNode.Icon);
//System.Windows.Forms.MessageBox.Show(iconCls);
treeNode.Listeners.Click.Handler = string.Format(new CultureInfo("en-US"), "#{{MainPanel}}.load('{0}');#{{MainPanel}}.setIconClass('{1}');#{{MainPanel}}.setTitle('{2}');", siteMapNode.Url, iconCls, siteMapNode.Title);
SiteMapNodeCollection children = siteMapNode.ChildNodes;
if (children != null && children.Count > 0)
{
foreach (SiteMapNode mapNode in siteMapNode.ChildNodes)
{
treeNode.Nodes.Add(this.CreateNode(mapNode));
}
}
return treeNode;
}
private string GetIconCls(Ext.Net.Icon icon)
{
string iconCls = this.ResourceManager1.GetIconClass(icon);
int pos = iconCls.IndexOf("{", StringComparison.OrdinalIgnoreCase);
return iconCls.Substring(1, pos - 1);
}
谢谢和问候。

我也尝试过 Selectable="true" 属性，但在静脉中。
