向ajax树视图控件添加按钮

Question

我有一个带有根节点，子节点和子子节点的树状视图。我需要为每个子子节点添加一个按钮。单击该按钮后，我需要使用该子节点ID填充popupextender。任何帮助将不胜感激。谢谢。

期望的视图：

*根节点

        1.child node 1
                   *(subchild node 1)  BUTTON 
                   *(subchild node 2)  BUTTON

        2.child node 2

                   *(subchild node 1)  BUTTON
                   *(subchild node 2)  BUTTON


 <asp:TreeView ID="TreeView1" EnableClientScript="true"  
 PopulateNodesFromClient="true"                              
 OnTreeNodePopulate="calltree" Font-Size="8pt"   runat="server" 
 ShowLines="True" HoverNodeStyle-Font-Underline="True" 
 SelectedNodeStyle-Font-Bold="True"  ParentNodeStyle-ForeColor="Black">
 <Nodes>
 <asp:TreeNode Text="Chart Of Cars" Selected="true" 
 SelectAction="Expand" PopulateOnDemand="true"/>
 </Nodes>
                                                </asp:TreeView>

背后的代码。cs：

公共无效调用树（对象发送者，TreeNodeEventArgs e）        {

       switch (e.Node.Depth)
       {
           case 0:
               HeaderTitle(e.Node);
               break;
           case 1:
               HeaderSubTitle(e.Node);
               break;

           default:
               break;
       }
   }

   public void HeaderTitle(TreeNode node)
   {
       DataSet ds_ParentNode = objcon.GetDataSet("select distinct 
       ProfileID,profilename from profile");

       foreach (DataRow row in ds_ParentNode.Tables[0].Rows)
       {
           TreeNode newNode = new TreeNode();
           newNode.Text = row["ProfileID"].ToString() + ' ' + row["profilename"].ToString();
           newNode.Value = row["ProfileID"].ToString();

           newNode.Expanded = false;
           newNode.SelectAction = TreeNodeSelectAction.Expand;
           newNode.PopulateOnDemand = true;
           node.ChildNodes.Add(newNode);
       }

   }

   public void HeaderSubTitle(TreeNode node)
   {
       DataSet ds_SubNode = objcon.GetDataSet("select distinct Profileext,profilepart from profilesert  where  ProfileID='" + node.Value + "'");
       foreach (DataRow row in ds_SubNode.Tables[0].Rows)
       {
           TreeNode newNode = new TreeNode();
           newNode.Text = row["Profileext"].ToString() + ' ' + row["profilepart"].ToString();
           newNode.Value = row["Profileext"].ToString();

           newNode.Expand();
           newNode.SelectAction = TreeNodeSelectAction.Expand;
           newNode.PopulateOnDemand = true;
           newNode.Expanded = false;
           node.ChildNodes.Add(newNode);
       }

   }
