我有一个 radtreeview，它由后面的代码中的数据库填充。我有一个想要触发的简单点击功能，但它似乎不起作用。这可能很简单。后面的代码有点难看，但没有做任何复杂的事情。这是我的 aspx 和后面的代码：
<%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="frmMain.aspx.cs" Inherits="MCMwebapp.frmMain" %>
<script type="text/javascript" language="javascript">
function ClientNodeClicked(sender, eventArgs) {
var node = eventArgs.get_node();
alert("You clicked " + node.get_text());
}
由于某种原因，结束脚本标签没有显示在编辑器上。
< telerik:RadTreeView ID="sitesTree" runat="server" OnClientNodeClicked="ClientNodeClicked">
<WebServiceSettings Path="MCMwebservice.Service1.asmx" Method="" />
</telerik:RadTreeView>
这是填充我的树的函数：
public void LoadSites(ref RadTreeView TreeSites, string Demogs, string Agencies, bool Config)
{
// Declare the SslConnection class variable.
SqlConnection sStateConn = new SqlConnection(Util.ConStrEpcrProd);
SqlConnection sZonesConn = new SqlConnection(Util.ConStrEpcrProd);
SqlConnection sAgenciesConn = new SqlConnection(Util.ConStrEpcrProd);
SqlCommand sStatesCmd = new SqlCommand("SELECT DISTINCT State FROM AMR_ZONE WHERE Zone_ID IN (" + Demogs + ") ORDER BY State");
SqlCommand sZonesCmd = new SqlCommand();
SqlCommand sAgenciesCmd = new SqlCommand();
sZonesCmd.Connection = sZonesConn;
sAgenciesCmd.Connection = sAgenciesConn;
sStatesCmd.Connection = sStateConn;
SqlDataReader objZonesReader;
SqlDataReader objAgenciesReader;
SqlDataReader objStateReader;
try
{
sStateConn.Open();
sZonesConn.Open();
sAgenciesConn.Open();
objStateReader = sStatesCmd.ExecuteReader();
TreeSites.Nodes.Add(new RadTreeNode("MEDS", "MEDSRoot"));
while (objStateReader.Read())
{
RadTreeNode StateNode = new RadTreeNode(objStateReader["State"].ToString());
StateNode.Text = objStateReader["State"].ToString();
(TreeSites.FindNodeByText("MEDS")).Nodes.Add(StateNode);
sZonesCmd.CommandText = "SELECT State,County,Zone_ID FROM AMR_ZONE WHERE State = '" + objStateReader["State"].ToString() + "' AND Zone_ID IN (" + Demogs + ") ORDER BY County";
objZonesReader = sZonesCmd.ExecuteReader();
while (objZonesReader.Read())
{
RadTreeNode ZoneNode = new RadTreeNode(objZonesReader["County"].ToString());
ZoneNode.Text = objZonesReader["Zone_ID"].ToString();
bool p = ZoneNode.PostBack;
(TreeSites.FindNodeByText("MEDS")).Nodes[StateNode.Index].Nodes.Add(ZoneNode);
if (!Config)
{
// If the sites are being loaded to grant user permissions, then load the agencies as well.
sAgenciesCmd.CommandText = "SELECT [DESC], CODE, Demog FROM AMR_AGEN WHERE Demog = " + ZoneNode.Text + " AND CODE IN(" + Agencies + ") ORDER BY [DESC]";
objAgenciesReader = sAgenciesCmd.ExecuteReader();
while (objAgenciesReader.Read())
{
RadTreeNode AgencyNode = new RadTreeNode(objAgenciesReader["DESC"].ToString());
//AP 1/24/2010 changed to name the node with the CODE value
//AgencyNode.Name = objAgenciesReader["DESC"].ToString();
AgencyNode.Text = objAgenciesReader["CODE"].ToString();
AgencyNode.Value = objAgenciesReader["CODE"].ToString() + objAgenciesReader["Demog"].ToString();
(TreeSites.FindNodeByText("MEDS")).Nodes[StateNode.Index].Nodes[ZoneNode.Index].Nodes.Add(AgencyNode);
}
objAgenciesReader.Close();
objAgenciesReader.Dispose();
}
}
objZonesReader.Close();
objZonesReader.Dispose();
}
objStateReader.Close();
objStateReader.Dispose();
}
