Repeater内的Gridviews

Question

我在我的页面上有一个中继器，它与一个用团队填充中继器的数据源链接。我的目标是为每个团队创建一个标题，并为每个团队创建一个GridView来修改每个团队的参与者。

问题：gridview的数据源需要团队的PK来从数据库中获取合适的玩家。我怎么能通过他们？

<asp:Repeater ID="Repeater1" runat="server" DataSourceID="odsTeam"> 
    <ItemTemplate> 
     <h1> 
      <%# Eval("name") %> 
      with maximum of 
      <%# Eval("st_max") %> 
      players.</h1> 

     <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="participant_id" 
      DataSourceID="odsParticipant"> 
      <Columns>

我知道有一个解决办法，我已经使用过一次......

首先把你的隐藏字段在您的中继器，并结合您的ID，然后在你的GridView的数据源提供的隐藏字段控制作为选择参数：

<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>
