hide node in treeview control

Question

I have a tree view created in my HTML Page

<asp:TreeView ID="TreeView1" runat="server" 
           onselectednodechanged="TreeView1_SelectedNodeChanged" 
           PopulateNodesFromClient="False" onunload="TreeView1_Unload">
           <Nodes>

               <asp:TreeNode Text="Reports" Value="Report">

               <asp:TreeNode Text="Status" Value="Service">
                   </asp:TreeNode>

                   <asp:TreeNode Text="Status" Value="Status">
                   </asp:TreeNode>

                   <asp:TreeNode Text="Stats" 
                       Value="Stats"></asp:TreeNode>

               </asp:TreeNode>
           </Nodes>
       </asp:TreeView>

now i want to hide the Stats node in the page load function in my code behind....

any suggestions.. thanks

I use Telerik RadTreeView; TreeView doesn't have DataBound event and Visible property for each node. Here is the code to remove the child node for TreeView.

protected void Page_Load(object sender, EventArgs e)
{
  RemoveNodeRecurrently(TreeView1.Nodes, "Status");
}

private void RemoveNodeRecurrently(TreeNodeCollection childNodeCollection, string text)
{
  foreach (TreeNode childNode in childNodeCollection)
  {
    if (childNode.ChildNodes.Count > 0)
      RemoveNodeRecurrently(childNode.ChildNodes, text);

    if (childNode.Text == text)
    {
      TreeNode parentNode = childNode.Parent;
      parentNode.ChildNodes.Remove(childNode);
      break;
    }
  }
}

You can try this, it works for Leaf Nodes only.

TreeView1.Nodes[0].Text = "";

TreeView1.Nodes[0].ShowCheckBox = false;

P.S: You will need a recursive function to access each node.

This doesn't seem to work with System.Windows.Forms.TreeView - the node's checkbox is still rendered.
