从代码隐藏动态填充 RadMenu

Question

我正在尝试在我的后台代码中动态填充 Telerik Radmenu 控件。我真的很难过。我需要能够将我的类别绑定到我的根元素，并将属性绑定到子元素。我真的迷失了。如果有人建议有更好的方法来执行此操作，即使它使用不同类型的菜单，我也很乐意尝试一下。提前致谢。

**编辑我的代码已更改。

protected void createFilter(int categoryid)
{

    // check cateogyrid 

    //get list of proudct id
    List<int> productIds = new List<int>();
    DataRow[] productRow = CategoriesProductsData.Tables["Products"].Select("Category_ID = " + 573);

    productIds = productRow.Select(p => int.Parse(p["Product_ID"].ToString())).ToList();

    //get attributes
    ITCProductService pService = new TCProductServiceClient();
    var productTuples = (pService.GetProductsAttributes(productIds));

    List<Tuple<int, CustomAttribute>> customAttributes = new List<Tuple<int, CustomAttribute>>();
    foreach (var productTuple in productTuples)
    {
        foreach (var attributeTuple in productTuple.m_Item2)
        {
            var customAttribute = new Tuple<int, CustomAttribute>(productTuple.m_Item1, new CustomAttribute(attributeTuple));
            customAttributes.Add(customAttribute);
        }
    }

    List<CustomAttributeCategory> categories = new List<CustomAttributeCategory>();

    var categoryTuples = customAttributes.Select(a => a.Item2).Select(a => a.Attribute.Category).Distinct();
    foreach (var categoryTuple in categoryTuples)
    {
        var category = new CustomAttributeCategory(categoryTuple);
        var attributeByCategory = customAttributes.Select(a => a.Item2).Where(b => b.Attribute.CategoryId == categoryTuple.AttributeCategoryId).Distinct();
        foreach (var attributeTuple in attributeByCategory)
        {

            var attribute = new CustomAttribute(attributeTuple.Attribute);
            var attributeProductIds = customAttributes.Where(a => a.Item2.Attribute.AttributeId == attributeTuple.Attribute.AttributeId).Select(a => a.Item1).ToList();
            attribute.ProductIds = attributeProductIds;


            category.Attributes.Add(attribute);
        }
        categories.Add(category);



        foreach (var cat in categories)
        {                              
            var itemCategory = new RadMenuItem(cat.Category.Name.ToString());
            handsetMenu.Items.Add(itemCategory);

            var itemAttribute = new RadMenuItem(cat.Attributes.ToString());
            handsetMenu.Items.Add(itemAttribute);
        }          
    }
}

 <%--RAD MENU--%>
            <telerik:RadMenu ID="handsetMenu" runat="server" ShowToggleHandle="true">                                  
            </telerik:RadMenu>

我认为 ItemDataBound 不是添加子项的正确位置。

是否要在每个根菜单项下添加相同的子项？

尝试在 DataBound 事件（在所有 itemDataBound 事件完成后触发）中迭代所有 RadMenu 项目。
