Need Help ASAP with Binding Sublevel Items

[Joshua]

I'm using RadMenu skin object in DNN.

For page that are level 3, I want to insert them under their level 2 parent as an undordered, bulleted list. (Please see attachment.)

How do I accomplish this dynamically?

I've tried using an itemTemplate, but that doesn't seem to be doing anything.  Perhaps, I'm going about this the wrong way.  Any immediate insight would be appreciated.

protected void Page_Load(object sender, EventArgs e)
{
    UnorderedListTemplate template = new UnorderedListTemplate();
    RadMenu menu = dnnMenu.FindControl("RadMenu1") as RadMenu;
    foreach (RadMenuItem item in menu.Items)
        template.InstantiateIn(item);
}

class UnorderedListTemplate : ITemplate
{
    public void InstantiateIn(Control container)
    {
        RadSiteMap rsMap = new RadSiteMap();
        rsMap.ID = "radSiteMap";
        rsMap.DataBinding += new EventHandler(MenuItem_DataBinding);
        container.Controls.Add(rsMap);
    }

    private void MenuItem_DataBinding(object sender, EventArgs e)
    {
        RadSiteMap target = (RadSiteMap)sender;
        RadMenuItem item = (RadMenuItem)target.BindingContainer;
        target.DataSource = (RadMenuItemCollection)DataBinder.Eval(item, "Items");
    }
}

Hello Joshua,

The desired appearance from the attached image resembles RadPanelBar. With RadPanelBar you should use ContentTemplate. Here is a help topic how to add templates dynamically. The Content template requires a little tweak, so here is na example:

public partial class DynamicContentTemplate : 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();
            template.InstantiateIn(item);
            item.DataBind();
        }
    }
}

class CustomContentTemplate : ITemplate
{
    public void InstantiateIn(Control container)
    {
        Label label1 = new Label();
        label1.Font.Bold = true;
        label1.DataBinding += new EventHandler(label1_DataBinding);
        container.Controls.Add(label1);
    }

    private void label1_DataBinding(object sender, EventArgs e)
    {
        Label target = (Label)sender;
        RadPanelItem item = (RadPanelItem)target.BindingContainer;
        target.Text = item.Value;
        //Alternative way:
        //string itemText = (string)DataBinder.Eval(item, "Value"); target.Text = itemText;
    }
}
