动态控件问题~~~

Question

这是HTML的DIV
<div id="Vip_grade" runat="server"></div>
在后台调用程序
public void vVipGrade()
{
Core cUserGrade=new Core();
ArrayList aBase=new ArrayList();
aBase=cUserGrade.aUsergrade(Server.MapPath("../AdminXml_Data.xml"),"Barbarism_Attribute/Grade_Configure/Vip_UserInfo");
for(int i=0;i<aBase.Count;i++)
{
string[] sVipGrade=aBase[i].ToString().Split(",".ToCharArray());
this.Vip_grade.InnerHtml=this.Vip_grade.InnerHtml+"<tr>"+
"<td class='domaint4' bgColor='#efefef' height='28'>VIP等级："+sVipGrade[0]+"</td>"+
"<td bgColor='#efefef' height='28' id='Table_td_"+sVipGrade[0]+"'><input id='Vip_"+sVipGrade[0]+"' type=text value='"+sVipGrade[2].Trim()+"' size='20'></td>"+
"<td class='Systemadmin_06' bgColor='#efefef' height='28'>&nbsp;<img src='../img/Upadmin/Upusergrade/"+sVipGrade[1]+"'></td>"+
"</tr>";
}
}生成INPUT后，我想单击按钮来获取INPUT的值，麻烦大家有什么好的解决方法吗？
