首先你的repeater里要存储ID才行

Answer 4

<asp:Repeater ID="cart" runat="server" OnItemDataBound="cart_ItemDataBound">
                 <HeaderTemplate>
                 </HeaderTemplate>
                <ItemTemplate>
                <tr>
 <td><%# Eval("ID")%></td>                <td><img src="upload/<%# Eval("ProductPic")%>" width="75" height="75"/></td>
                <td class="product"><b><%# Eval("ProductName")%></b></td>
                <td><asp:TextBox ID="num" runat="server" style="width:60px;"></asp:TextBox></td>
                </tr>
                </ItemTemplate>
                <HeaderTemplate>
                </HeaderTemplate>
                </asp:Repeater>

<asp:Repeater ID="cart" runat="server" OnItemDataBound="cart_ItemDataBound">
  <HeaderTemplate>
  </HeaderTemplate>
  <ItemTemplate>
  <tr>
 <td><asp:Label ID="ID"  runat="server" Text='<%# Eval("ID")%>'></asp:Label></td>  <td><img src="upload/<%# Eval("ProductPic")%>" width="75" height="75"/></td>
  <td class="product"><b><%# Eval("ProductName")%></b></td>
  <td><asp:TextBox ID="num" runat="server" style="width:60px;"></asp:TextBox></td>
  </tr>
  </ItemTemplate>
  <HeaderTemplate>
  </HeaderTemplate>
  </asp:Repeater>  for (int i = 0; i < this.cart.Items.Count; i++)
            {
               Label ID= (Label)this.cart.Items[i].FindControl("ID");
               string strID=ID.Text;
                TextBox txt = (TextBox)this.cart.Items[i].FindControl("num");
                string num= txt.Text; 
            }
