Hi, I have an asp.net application and wish to convert the asp menu to a rad menu and need some help with the code behind.  Here is the current asp menu code behind.

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using Vevo;
using Vevo.DataAccessCache;
using Vevo.DataAccessLib;

public partial class Components_CategoryNavMenuList : Vevo.Language.BaseLanguageUserControl
{
    private int _nodeDepth = 0;
    private int _maxNode = 0;
    
    private string CategoryID
    {
        get
        {
            string id = Request.QueryString["CategoryID"];
            if (String.IsNullOrEmpty( id ))
                return "0";
            else
                return id;
        }
    }


    private string CategoryName
    {
        get
        {
            if (Request.QueryString["CategoryName"] == null)
                return String.Empty;
            else
                return Request.QueryString["CategoryName"];
        }
    }

    private void PopulateControls()
    {
        DataTable table = CategoryAccessCache.Instance.GetByParentID(
            CultureUtilities.StoreCultureID, "0", "SortOrder", FlagFilter.ShowTrue );

        uxCategoryNavListMenu.Items.Clear();
        foreach (DataRow row in table.Rows)
        {
            uxCategoryNavListMenu.Items.Add( NewItem( row ) );
            _nodeDepth = 0;
        }

        foreach (MenuItem mi in uxCategoryNavListMenu.Items)
        {
            CategoryItem( mi, CategoryID, CategoryName );
        }
    }

    private void CategoryItem( MenuItem menuItem, string categoryID, string categoryName )
    {
        if (menuItem.Value == categoryID || menuItem.Text == categoryName)

                    return;
                }
                CategoryItem( mi, categoryID, categoryName );
            }
        }
    }

    private void PopulateCategories( MenuItem item, string parentCategoryID )
    {
        DataTable table = CategoryAccessCache.Instance.GetByParentID( CultureUtilities.StoreCultureID, parentCategoryID, "SortOrder", FlagFilter.ShowTrue );

        foreach (DataRow row in table.Rows)

        {
            newItem.NavigateUrl = UrlManager.GetCategoryUrl( row["CategoryID"].ToString(), row["UrlName"].ToString() );

            _nodeDepth++;
            if (_nodeDepth < MaxNode) //Max Tree depth
                PopulateCategories( newItem, row["CategoryID"].ToString() );
            _nodeDepth--;
        }
        else

            newItem.NavigateUrl = UrlManager.GetCategoryUrl( row["CategoryID"].ToString(), row["UrlName"].ToString() );
        }
        return newItem;
    }


    protected void Page_Load( object sender, EventArgs e )
