请教关于动态生成控件的问题？

foreach (SubTitleEntity se in sl)
            {
                div1.InnerHtml += "<tr><th colspan='2' style='font-size:x-large;'>" + se.SubName + "</th></tr><tr><td colspan='2'></td></tr>";
                IList<QuesionEntity> ql = qs.GetQuestionBySubID(se.SubID);
                foreach (QuesionEntity qe in ql)
                {
                    if (qe.Qtype.ToString() == "2")
                    {
                        div1.InnerHtml += ("<tr><td style='width:28%'>Q" + i + "  " + qe.Qname + "</td><td> <input type='text' /></td></tr>");
                    }
                    else if (qe.Qtype.ToString() == "1")
                    {
                        div1.InnerHtml += ("<tr><td style='width:28%'>Q" + i + "  " + qe.Qname + "</td><td><input type='checkbox' /> </td></tr>");
                    }
                    else
                    {
                        div1.InnerHtml += ("<table width='100%'><tr><td colspan='2'>Q" + i + "  " + qe.Qname + "</td></tr>");
                    }
要用textbox代替红字部分，不知道该怎么做，请各位高手教教我，谢谢！如果是一组radio呢？
