Trying change an element in NodeTemplate

[Tonyz289]

I am trying to change one element in the NodeTemplate of a Treeview and my code is not working. It executes fine but the change doesn't show up on the screen. What am I doing wrong?

Here is the the code:

protected void RadTreeView1_NodeDataBound (object sender, RadTreeNodeEventArgs e)

{

    e.Node.ExpandMode = TreeNodeExpandMode.ServerSide;

    if (e.Node.Text == "Retailers")

    {

        RadTreeNode node = RadTreeView1.Nodes[0];

        HyperLink hyperLink = (HyperLink)node.FindControl ("HyperLink2");

        hyperLink.Visible = false;  // this what is want to do


        hyperLink.Text = "<span style=\"color: #BBBBBB\">X</span>"; // this is test to see that the Hyperlink Text changes


    // Neither of the above two lines produce the screen changes I am looking for
      }

}

Here is the defintion

<telerik:RadTreeView ID="RadTreeView1" runat="server" CheckBoxes="True" MultipleSelect="True"
    EnableViewState="true" ShowLineImages="False" EnableEmbeddedSkins="False" Skin="tree_2"
    OnNodeClick="RadTreeView1_NodeClick" OnNodeDataBound="RadTreeView1_NodeDataBound"
    OnClientNodeCollapsed="OnClientNodeCollapsed" OnClientNodeExpanded="OnClientNodeExpanded" OnClientLoad="onLoad">
    <NodeTemplate>
        <small>
            <asp:Label ID="lblnodeText" Text='<%#Eval("Title") %>' runat="server" /><asp:Label
                ID="lblCatId" Text='<%#Eval("Id") %>' runat="server" Visible="false"></asp:Label><asp:Label
                    ID="lblisCustomer" Text='<%#Eval("isCustomer") %>' runat="server" Visible="false"></asp:Label><asp:Label
                        ID="Description" runat="server" Text='<%#Eval("description") %>' Visible="false" /><asp:HiddenField
                            ID="DescriptionVisible" runat="server" Value='<%#Eval("descriptionVisible") %>' />
        </small>
        <small>
<asp:HyperLink ID="HyperLink2" runat="server" NavigateUrl=<%# "javascript:Popup_Window('category_detail','" + DataBinder.Eval(Container.DataItem, "id").ToString() + "')"%> style="text-decoration: none;"><span style="color: #BBBBBB">e</span></asp:HyperLink>
        </small>
    </NodeTemplate>
</telerik:RadTreeView>

Hello Tony,

I prepared a very simplified runnable page that demonstrates the desired approach. I can find the control in the node template and set its visibility property to false. Give it a try and let me know how it goes from your side.
