c# - 如何获取RadTreeView的点击节点文本

Question

如何在C#中获取RadTreeView中点击节点的文本？我添加了 OnNodeClick 事件，但它没有触发。请告诉我如何在 C# 中获取单击节点的文本。

ASP.NET:

<telerik:RadTreeView ID="CandidatesTreeMenu" OnClientNodeClicked="ClientCandidateMenuNodeClicked" Skin="Vista" runat="server" OnNodeClick="CandidatesTreeMenu_NodeClick">
    <Nodes>
        <telerik:RadTreeNode Text="Added" NavigateUrl="NewCandidateList.aspx?type=recently">
        </telerik:RadTreeNode>
        <telerik:RadTreeNode Text="Candidates" NavigateUrl="NewCandidateList.aspx?type=My">
        </telerik:RadTreeNode>
    </Nodes>
</telerik:RadTreeView>

代码隐藏:

protected void CandidatesTreeMenu_NodeClick(object sender, RadTreeNodeEventArgs e)
{
    try
    {
        string CheckNodeName = e.Node.Text;

    }
    catch { }
}

您需要在用户控件 page_load 事件中的每次回发时重新绑定(bind)。这是我在 ascx 中使用的代码:

<script runat="server">

    protected void Page_Load(object sender, EventArgs e)
    {
        CandidatesTreeMenu.NodeClick += CandidatesTreeMenu_NodeClick;
    }
    protected void CandidatesTreeMenu_NodeClick(object sender, RadTreeNodeEventArgs e)
    {
        string CheckNodeName = e.Node.Text;
    }

</script>
<telerik:RadScriptBlock runat="server">
    <script type="text/javascript">
        function ClientCandidateMenuNodeClicked(sender, args) {
            // noop
        }
    </script>
</telerik:RadScriptBlock>
<telerik:RadTreeView ID="CandidatesTreeMenu" OnClientNodeClicked="ClientCandidateMenuNodeClicked" Skin="Vista" runat="server">
    <Nodes>
        <telerik:RadTreeNode Text="Added" NavigateUrl="NewCandidateList.aspx?type=recently">
        </telerik:RadTreeNode>
        <telerik:RadTreeNode Text="Candidates" NavigateUrl="NewCandidateList.aspx?type=My">
        </telerik:RadTreeNode>
    </Nodes>
</telerik:RadTreeView>
