</html>

后台：

protected void TreeView1_SelectedNodeChanged(object sender, EventArgs e)

    {

        TextBox1.Text = TreeView1.SelectedValue.ToString();

    }

开始是显示了jQuery EasyUI布局框架的，我点击TreeView节点，右边TextBox里也能显示相应的数值，但是这种情况下页面会跳动。所以我就像加ScriptManager和UpdatePanel，让页面不刷新，可是我怎么设置UpdatePanel下面的Triggers属性都不行，不是根本就不触发TreeView的节点改变事件，就是触发了但是页面还是跳动。
