Why does ASP.Net RadioButton and CheckBox render inside a Span?

Question

I would expect this:

Answer 1

the best way i think is this:

    public class HtmlTextWriterNoSpan : HtmlTextWriter
    {
        public HtmlTextWriterNoSpan(TextWriter textWriter) : base(textWriter)
        { 
        }

        protected override bool OnTagRender(string name, HtmlTextWriterTag key)
        {
            if (name == HtmlTextWriterTag.Span)
            {
                return false;
            }

            return base.OnTagRender(name, key);
        }
    }

to use it in custom control:

    protected override void Render(HtmlTextWriter writer)
    {
        writer = new HtmlTextWriterNoSpan(writer);
        base.Render(writer);
        // HERE MORE CODE
    }
