RadMenu loading user controls not working

[Ashley]

I am attempting to load user controls inside a PlaceHolder using a RadMenu. Ajax manager is updating both the menu and the placeholder. When I click on the menu item nothing happens. Initially, when the page loads the homeview.ascx user control does load, but it is not updated on menuitem click.

 ASPX Page

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
                        <AjaxSettings>
                            <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
                                <UpdatedControls>
                                    <telerik:AjaxUpdatedControl ControlID="MainNav" />
                                    <telerik:AjaxUpdatedControl ControlID="BodyContent" LoadingPanelID="RadAjaxLoadingPanel1" />
                                </UpdatedControls>
                            </telerik:AjaxSetting>
                        </AjaxSettings>
                    </telerik:RadAjaxManager>
                <!-- Main Menu -->
                    <div class="menu-wrapper" style="border-top: solid 40px #b1ddab;">
                        <telerik:RadMenu runat="server" ID="MainNav" EnableEmbeddedSkins="false" OnItemClick="MainNav_OnItemClick" CssClass="desktop_nav_menu" >
                            <Items>
                                <telerik:RadMenuItem Text="<%$ Resources:Main, MasterHome %>" />
                                <telerik:RadMenuItem Text="<%$ Resources:Main, MasterTraining %>" />
                                <telerik:RadMenuItem Text="<%$ Resources:Main, MasterSupport %>" />
                            </Items>
                        </telerik:RadMenu>
                    </div>
                <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server"></telerik:RadAjaxLoadingPanel>
                <asp:PlaceHolder ID="BodyContent" runat="server">

                </asp:PlaceHolder>

Code Behind

protected void Page_Load(object sender, EventArgs e)
    {
        this.LoadView();
    }

private string LoadedControlName
    {
        get
        {
            return (this.ViewState[ViewStateKeys.LoadedControlName] as string) ?? defaultContentControl;
        }
        set
        {
            this.ViewState[ViewStateKeys.LoadedControlName] = value;
        }
    }

private void LoadView()
    {
        this.LoadView(this.LoadedControlName);
    }

    private void LoadView(string viewName)
    {
        Control control = this.LoadControl(string.Concat(SitePaths.Views, viewName));
        control.ID = viewName;
        this.LoadedControlName = viewName;
        this.BodyContent.Controls.Clear();
        this.BodyContent.Controls.Add(control);
    }

    public void MainNav_OnItemClick(object sender, RadMenuEventArgs e)
    {
        RadMenuItem currentItem = e.Item;
        string currentItemText = currentItem.Text;
        string controlPath = string.Empty;
        switch (currentItemText)
        {
            case ("Home"):
                controlPath = DefaultViews.Home;
                break;
            case ("Training"):
                controlPath = DefaultViews.Training;
                break;
            case ("Support"):
                controlPath = DefaultViews.Support;
                break;
            default:
                break;
        }
        if (!String.IsNullOrEmpty(controlPath))
        {
            this.LoadView(controlPath);
        }
    }

View Constants

public class SitePaths
{
    public const string Views = "~/Views/";
}

public class ViewStateKeys
{
    public const string LoadedControlName = "LoadedControlName";
}

public class DefaultViews
{
    public const string Home = "HomeView.ascx";
    public const string Training = "TrainingView.ascx";
    public const string Support = "SupportView.ascx";
}

I figured it out myself.

I had the radmanager configuration wrong.

Corrected Code

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="RadAjaxLoadingPanel1">
                        <AjaxSettings>
                            <telerik:AjaxSetting AjaxControlID="MainNav">
                                <UpdatedControls>
                                    <telerik:AjaxUpdatedControl ControlID="BodyContent"/>
                                </UpdatedControls>
                            </telerik:AjaxSetting>
                        </AjaxSettings>
                    </telerik:RadAjaxManager>
