Asp.net 中继器内部的网格视图

我的页面上有一个中继器，与一个数据源链接，该数据源用团队填充中继器。我的目标是为每个团队创建一个标题，为每个团队创建一个gridview来修改每个团队中的球员

问题：gridview的数据源需要团队的PK才能从数据库中找到合适的玩家。我怎样才能通过他们

            <%# Eval("st_max") %>
            players.</h1>

我知道我曾经使用过的一种变通方法

首先，将隐藏字段放入中继器并绑定id，然后在gridview数据源中提供一个隐藏字段控件作为选择参数：

 <h1>
        <%# Eval("name") %>
        with maximum of
        <%# Eval("st_max") %>
        players.</h1>
<asp:HiddenField runat="server" ID="hdfId" Value='<%# Eval("TeamId") %>' />

    <asp:ObjectDataSource ID="odsTeam" runat="server" OldValuesParameterFormatString="original_{0}"
        OnSelecting="odsTeam_Selecting" SelectMethod="GetTeamsByDelegationID" TypeName="TeamBLL">
        <SelectParameters>
             <asp:ControlParameter PropertyName="value" Name="delegation_id" ControlID="hdfId" Type="Int32" />
        </SelectParameters>
    </asp:ObjectDataSource>

谢谢！还有一个问题：有没有办法在设计模式下修改gridview，因为在VS2008:Dno中中继器在设计模式下不显示gridview您不能在中继器中这样做。但有一种方法，您可以将此gridview转到另一个页面，并在那里进行修改，然后再次将该源文件从那里复制到此页面。
