如图，想请教一下大家，我有一个作业，要求我们做一个简单的购物网站，在商品列表这，我用了ACCESSDATASOURCE，然后用REPEATER弄了个表格，并设计了一个直接添加到购物车的按钮，其他的没问题了，就是不知道怎么获取amount列的textbox里的值，希望大家赐教该怎么做，我是用VB写网页的

对了，忘了附上代码了，补上补上   

<asp:Repeater ID="Repeater1" runat="server" DataSourceID="AccessDataSource1">
    <HeaderTemplate>
        <table border="1" cellpadding="0" cellspacing="0">
           <tr>
              <td colspan="6" align="center">   Product List
              </td>
           </tr>
           <tr>
              <td>
                 product id
              </td>
              <td>
                 product name
              </td>
              <td>
                 price
              </td>
              <td>
                 catalogue
              </td>
              <td>
                 amount
              </td>
              <td>
                 manipulation
              </td>
           </tr>
    </HeaderTemplate>
    <ItemTemplate>
        <tr>
           <td>
              <%#Eval("productid")%>
           </td>
           <td>
              <%#Eval("product_name")%>
           </td>
           <td>

           </td>
           <td>
              <%#Eval("catalogueid")%>
           </td>
           <td>
               <asp:TextBox ID="TextBoxamount" runat="server" Text="1" Width=40 MaxLength=6></asp:TextBox>
           </td>
           <td>
               <asp:Button ID="Buttondetail" runat="server" Text="detail" CommandName="detail" CommandArgument='<%#Eval("productid") %>'/>
               <asp:Button ID="Buttonputincart" runat="server" Text="put in cart" CommandName="put in cart" CommandArgument='<%#Eval("productid") %>'/>
           </td>
