Dynamic Binding to RadPanelBar Content Template

[Nathan]

I am trying to bind to the Content Template of a RadPanelBar with and object (see below).  I am able to get the Panel Labels to display but the panel items are not expandable and they don't show the Rad Text Box inside the content. 

 

 

 <telerik:RadPanelBar  RenderMode="Lightweight" ID="RadPanelBar1" Runat="server"  Width="75%">
            <Items>
                <telerik:RadPanelItem runat="server">
                    <ContentTemplate>
                         <telerik:RadTextBox ID="RadTextBox1" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "DetailMessage") %>'></telerik:RadTextBox>
                    
                    </ContentTemplate>
                </telerik:RadPanelItem>
            </Items>
            </telerik:RadPanelBar>

        public class DetailInfo
        {
            public string DetailMessage { get; set; }
        }
        public class PanelInfo
        {
            public int PanelId { get; set; }
            public string PanelLabel { get; set; }
            public DetailInfo Details { get; set; }
            public string DetailMessage {get; set; }
        }

        protected void Page_Load(object sender, EventArgs e)
        {
            List<PanelInfo> PanelLabels = Enumerable.Range(1, 10).Select(m =>
                 new PanelInfo
                 {
                     PanelLabel = String.Format("Panel {0}", m),
                     PanelId = m,
                     Details = new DetailInfo { DetailMessage = string.Format("Detail {0}", m) },
                     DetailMessage = String.Format("Message {0}", m),
                 }
               ).ToList();

            RadPanelBar1.DataSource = PanelLabels;
            RadPanelBar1.DataTextField = "PanelLabel";
            RadPanelBar1.DataValueField = "PanelId";
            RadPanelBar1.DataBind();
          
        }

Hello Nathan,

The ContentTemplate used in the provided code snippet is only for the specific item. Using the server-side binding provided in the code snippet creates new items which does not have ContentTemplate. 

In order to achieve setting the ContentTemplate for all items, one option is to use Server Templates and the OnTemplateNeeded event. 

Please find attached a sample project we prepared based on the provided code snippets.
