+## Description
+
+Sometimes, one might want to get a reference to an **iframe** element inside the ItemTemplate of the Rotator
+
+## Solution
+
+The easiest way to get the iframe element would be to attach a handler to the Rotator's [`ItemDataBound`]({%slug rotator/server-side-programming/events%}) server-side event and find the target iframe element in the current item:
+
+````ASP.NET
+<telerik:RadRotator RenderMode="Lightweight" ID="RadRotator1" runat="server" OnItemDataBound="RadRotator1_ItemDataBound">
+    <ItemTemplate>
+        <iframe id="iframe1" runat="server">
+            <asp:Image runat="server" ID="image1" />
+        </iframe>
+    </ItemTemplate>
+</telerik:RadRotator>
+````
+
+````C#
+private void Page_Load(object sender, System.EventArgs e)
+{
+    if (!IsPostBack)
+    {
+        RadRotator1.DataSource = GetRotatorDataSource();
+        RadRotator1.DataBind();
+    }
+}
+
+private string[] GetRotatorDataSource()
+{
+    string[] clients = { "ANATR", "ANTON", "BOTTM", "CACTU", "CENTC", "ERNSH", "LAUGB", "MAISD", "MEREP", "OCEAN" };
+    return clients;
+}
+
+protected void RadRotator1_ItemDataBound(object sender, RadRotatorEventArgs e)
+{
+    HtmlIframe iframe = e.Item.Controls[1] as HtmlIframe; // Find the iframe server control
+}
+````
