再问gridview与detailsview关联的问题

刚才问了有关gridview与detailsview关联的问题
就是如何选定gridview的一行后在detailsview中显示这行的详细信息
我按着大家给的方法试了一下，将两个控件都绑定到同一个数据源控件，再加上如下代码。但是还有问题<asp:SqlDataSource ID="SqlDataSource1" runat="server"FilterExpression="CproductName='@CproductName'"selectcommand="Select * FROM [product]"...>            <filterparameters>
                <asp:ControlParameter Name="CproductName"
                 ControlId="GridView1" 
                 PropertyName="SelectedValue" />
            </filterparameters>但是在gridview中点了select之后 页面上什么都没有，请问 这是怎么回事啊？
请高手解决！
