    Hi Team, 
     My Requirement is to open PDF File in Rad Panel Item. When I do it from design mode it is working fine, but I am unable to add Iframe from code behind.
    When I used Iframe from design mode : 
                     <telerik:RadPanelBar ID="radSample" runat="server">
                               <iframe id="sample123" runat="server" src="~/UpLoadedImages/abc.pdf"></iframe>
      when I used like this it is working fine and pdf is opening in Iframe but now i need to add rad panel items dynamically,
    but as per my requirement i may have add number of rad panel items  so for that,     
    count = no. of items;
    foreach(int i=0 ; i < count; i++)
                             RadPanelItem myItem= new RadPanelItem();
     System.Web.UI.HtmlControls.HtmlGenericControl Iframe1 = new System.Web.UI.HtmlControls.HtmlGenericControl();
                            Iframe1.Attributes["src"] = "~/UpLoadedImages/abc.pdf";
    Now IFrame is adding like a span tag and not working as expected.

    Can you help me how to add Iframe control to Rad Panel Item dynamically....

     Thanks in Advance..

    Hi Santhosh,

    Here is an example of how you can add an iframe in a ContentTemplate of a RadPanelBar control using code behind:
    public partial class PanelBar_PanelBar1 : System.Web.UI.Page
        protected void Page_Load(object sender, EventArgs e)
            CustomContentTemplate template = new CustomContentTemplate();
            foreach (RadPanelItem item in RadPanelBar1.Items)
                item.ContentTemplate = new CustomContentTemplate();
        class CustomContentTemplate : ITemplate
            public void InstantiateIn(Control container)
                var Iframe1 = new HtmlGenericControl("IFRAME");
                Iframe1.Attributes["height"] = "300px";
                Iframe1.Attributes["width"] = "300px";
                Label label1 = new Label();
                label1.Text = "neeeew";
                label1.Font.Bold = true;

    <telerik:RadPanelBar ID="RadPanelBar1" runat="server">
              <telerik:RadPanelItem runat="server" Text="Root RadPanelItem1" Value="A">
              <telerik:RadPanelItem runat="server" Text="Root RadPanelItem2" Value="B">
              <telerik:RadPanelItem runat="server" Text="Root RadPanelItem3" Value="C">
