自定义Web控件html渲染

Question

This is my code , i created my custum radiobuttonlist. And it works but.. take a look at the code guys. Im using umbraco and C#

    using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Linq;
using System.Text;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using umbraco;
using umbraco.BusinessLogic;
using umbraco.cms.businesslogic.member;
using System.Web.Security;
using umbraco.cms.businesslogic.web;
using System.Collections;

namespace RadioButtonList
{

    [DefaultProperty("Text")]
    [ToolboxData("<{0}:RadioButtonList runat=server></{0}:RadioButtonList>")]
    public class RadioButtonList : System.Web.UI.WebControls.RadioButtonList
    {
        [Bindable(true)]
        [Category("Appearance")]
        [DefaultValue("")]
        [Localizable(true)]

        private void populate()

    {
        foreach (umbraco.cms.businesslogic.Dictionary.DictionaryItem d in umbraco.cms.businesslogic.Dictionary.getTopMostItems)
        {
            if (d.hasChildren)
            {
                foreach (umbraco.cms.businesslogic.Dictionary.DictionaryItem d1 in d.Children)
                {
                    if (d1.hasChildren)
                    {
                        if (d1.Value(1) == "Target Groups")
                        {
                            SortedList list = new SortedList();
                            foreach (umbraco.cms.businesslogic.Dictionary.DictionaryItem d2 in d1.Children)
                            {
                                string translation;
                                int lang = umbraco.library.GetCurrentDomains(umbraco.presentation.nodeFactory.Node.GetCurrent().Id)[0].Language.id;
                                translation = "";
                                translation = new umbraco.cms.businesslogic.Dictionary.DictionaryItem(d2.key).Value(lang);

                                list.Add(translation, d2.key);



                            }
                            this.DataSource = list;
                            this.DataValueField = "value";
                            this.DataTextField = "key";
                            this.DataBind();


                        }

                    }
                }

            }
        }
    }


        protected override void OnPreRender(EventArgs e)

        {

            base.OnPreRender(e);

            populate();

        }

    }

It works i can get the new web control but i want to "control" the render html. My RadioButtonList renders a span but i dont want it cause it create some issues. I already tryed this

protected override void Render(HtmlTextWriter writer)
{
RenderContents(writer);
}

But when i use this my radiobuttonlist disappears and i cant see it anymore. I really need help cause im new to this and its my 1st time using custum server controls.

You need to set the RepeatLayout Property on it. Anything but Flow will get rid of the span, but it depends what you want to replace it with as to what value you want.
