Master-detail pages for products

Hello,

I have a page for products which links to another page for a more detailed page for a specific product the user selects.

In design view, I've attached a objectdatasource and datalist in design view on the detailed page. Sonething like this:

Code:

---

    <asp:DataList ID="DataList1" runat="server" DataSourceID="ObjectDataSource1">
        <ItemTemplate>
            <div class="productDetail">
                <img src="<%=ResolveClientUrl("~/images/")%><%#Eval("LargeImage")%>" />

                <div>
                    <h1><%#Eval("Name")%></h1>
                    <p><%#Eval("Description")%></p>
                    <span>£<%#Eval("Price")%></span><asp:RadioButton ID="standardDeliveryRb" runat="server" GroupName="deliveryGroup" Checked="true" Text=" Standard Delivery - £4.99" />
                    <br />
                    <br />
                    <asp:RadioButton ID="NextDayDeliveryRb" GroupName="deliveryGroup" runat="server" Text=" Next Day Delivery - £7.99" />
                    <br />
                    <br />
                    <br />

                    <asp:Button
                        ID="addToCartBtn"
                        runat="server"
                        Text="Add to Cart"
                        OnClick="addToCartBtn_Click" />
                </div>
            </div>     
        </ItemTemplate>
    </asp:DataList>

Obviously, as its the detail view I only want a single record so a list type control is too much but I couldn't find an alternative, is there one?

Also, when the user clicks on a button I want it to redirect to a page and pass the productId in the url header. How can I access the datasource from the code behind, the way it's done using eval on the front end without running another database query.

Thanks
