DataKeyNames问题与我的GridView

Question

我一直有这个问题，我的DataKeyNames值。每行的主键是GameID，但每当我设置DataKeyNames等于GameID，它都不起作用。

我在我的gridview中启用选择，因为我想额外的信息放在formview上。所以，当用户点击Select时，formview会显示该行的附加信息。

<asp:GridView ID="GridView1" runat="server" AllowPaging="True" 
    AutoGenerateColumns="False" CellPadding="4" DataSourceID="SqlDataSource1" DataKeyNames="Team, Opponent" 
    ForeColor="#333333" GridLines="None" Height="360px" Width="641px" 
    onselectedindexchanged="GridView1_SelectedIndexChanged" > 
<AlternatingRowStyle BackColor="White" /> 

<Columns> 
    <asp:BoundField DataField="Team" HeaderText="Team" SortExpression="Team" /> 
    <asp:BoundField DataField="Opponent" HeaderText="Opponent" 
     SortExpression="Opponent" /> 
    <asp:BoundField DataField="Date" HeaderText="Date" SortExpression="Date" /> 
</Columns> 

<FooterStyle BackColor="#990000" Font-Bold="True" ForeColor="White" /> 
<HeaderStyle BackColor="#990000" Font-Bold="True" ForeColor="White" /> 
<PagerStyle BackColor="#FFCC66" ForeColor="#333333" HorizontalAlign="Center" /> 
<RowStyle BackColor="#FFFBD6" ForeColor="#333333" /> 
<SelectedRowStyle BackColor="#FFCC66" Font-Bold="True" ForeColor="Navy" /> 
<SortedAscendingCellStyle BackColor="#FDF5AC" /> 
<SortedAscendingHeaderStyle BackColor="#4D0000" /> 
<SortedDescendingCellStyle BackColor="#FCF6C0" /> 
<SortedDescendingHeaderStyle BackColor="#820000" /> 
</asp:GridView> 

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:ConnectionString %>" 
    SelectCommand="SELECT [Team], [Opponent], [Date] FROM [game] WHERE ([Team] = @Team)"> 
    <SelectParameters> 
     <asp:ControlParameter ControlID="GridView1" DefaultValue="Arsenal" Name="Team" 
      PropertyName="SelectedValue" Type="String" /> 
    </SelectParameters> 
</asp:SqlDataSource> 

Answer 1

你的意思的
DataKeyNames="Team, Opponent"到DataKeyNames="GameID"变化？如果是这样，您还必须将GameID添加到SqlDatasource的选择查询中。你的粘贴代码只出现Team和``对手。

变化
SelectCommand="SELECT [Team], [Opponent], [Date] FROM [game] WHERE ([Team] = @Team)">
到
SelectCommand="SELECT [GameID], [Team], [Opponent], [Date] FROM [game] WHERE ([Team] = @Team)">

假设条件是，在表中字段的名称，是游戏ID。
