+## Description
+
+I want to add a text link to the right of specific RadTreeNode elements in my [RadTreeView](https://docs.telerik.com/devtools/aspnet-ajax/controls/treeview/overview) while loading data from an XML file. I need a solution that allows me to include the link URL and text as part of the XML structure and manipulate the nodes to display the links dynamically.
+
+This knowledge base article also answers the following questions:
+- How to add a hyperlink next to RadTreeNode elements in RadTreeView?
+- How to customize RadTreeNode with a link using XML data?
+- How to use NodeDataBound for adding links dynamically?
+
+## Solution
+
+To achieve this, extend the XML structure to include the link properties (e.g., URL) using the `NavigateUrlField` property. Use a `NodeTemplate` to render the link alongside the RadTreeNode text.
+
+### XML Structure Example
+
+Update your XML file to include the URL for each node where you want the link to appear:
+
+````XML
+<Tree>
+	<Node Text="Desktop" Expanded="True" ToolTip="Desktop" Url="Default2.aspx">
+		<Node Text="Administrator" Url="Default3.aspx" Expanded="True">
+			<Node Text="AppData" Url="Default4.aspx">
+				<Node Text="Microsoft"  Url="Default5.aspx"/>
+			</Node>
+			<Node Text="Contacts" />
+			<Node Text="Downloads"  Url="Default6.aspx"/>
+		</Node>
+	</Node>
+</Tree>
+````
+
+Use the following configuration for your RadTreeView control:
+
+````ASP.NET
+<telerik:RadTreeView ID="RadTreeView2" runat="server" DataSourceID="XmlDataSource1" OnNodeDataBound="RadTreeView1_NodeDataBound">
+    <NodeTemplate>
+        <%# DataBinder.Eval(Container, "Text") %>
+        <asp:HyperLink ID="SectionLink" runat="server" Visible="false"></asp:HyperLink>
+    </NodeTemplate>
+    <DataBindings>
+        <telerik:RadTreeNodeBinding DataMember="Node" TextField="Text" NavigateUrlField="Url" ExpandedField="Expanded"></telerik:RadTreeNodeBinding>
+    </DataBindings>
+</telerik:RadTreeView>
+
+<asp:XmlDataSource runat="server" ID="XmlDataSource1" DataFile="TreeView.xml" XPath="/Tree/Node"></asp:XmlDataSource>
+````
+
+Use the `NodeDataBound` event to dynamically set the properties of the link:
+
+````C#
+protected void RadTreeView1_NodeDataBound(object sender, RadTreeNodeEventArgs e)
+{
+    string url = e.Node.NavigateUrl;
+
+    if (!string.IsNullOrEmpty(url))
+    {
+        HyperLink link = (HyperLink)e.Node.FindControl("SectionLink");
+
+        if (link != null)
+        {
+            link.Text = url;
+            link.NavigateUrl = url;
+            link.Visible = true;
+            link.Style.Add("margin-left", "10px");
+        }
+    }
+}
+````
+
+This approach allows you to control which nodes display a link dynamically based on the XML data while keeping the structure data-driven.
