從gridview刪除行

我有2個表格MachineGroups和Machines。 MachineGroups有列：從gridview刪除行

MachinegroupID 
MachineGroupName 
MachineGroupDesc

和機器中的列：

MachineGroupID (FK) 
MachineID 
MachineName 
Machinedesc

現在我想刪除machinegroup，但不是必須的機器在裏面的人。

DELETE FROM MachineGroups 
WHERE MachineGroupID NOT IN (SELECT DISTINCT MachineGroupID FROM Machines)

這將刪除gridview中沒有的所有行。機器= 0 我要的是隻刪除其刪除鏈接被點擊的行...

@unknown：你需要了解如何正確格式化XML和代碼片段！突出顯示有問題的行，然後單擊編輯工具欄上的「代碼」按鈕（010 101），或者在鍵盤上按下Ctrl-K - 只有代碼正確顯示並且其他人才能看到回答您的問題！ – 2009-09-28 05:49:55

謝謝..我記得下次 – user175084 2009-09-28 05:55:00

沒有測試，但方向應該是正確的：

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:SumooHAgentDBConnectionString %>" 
    SelectCommand="SELECT MachineGroups.MachineGroupID, MachineGroups.MachineGroupName, MachineGroups.MachineGroupDesc, MachineGroups.TimeAdded, MachineGroups.CanBeDeleted, COUNT(Machines.MachineName) AS 'No. of PCs' FROM MachineGroups FULL OUTER JOIN Machines ON Machines.MachineGroupID = MachineGroups.MachineGroupID GROUP BY MachineGroups.MachineGroupID, MachineGroups.MachineGroupName, MachineGroups.MachineGroupDesc, MachineGroups.TimeAdded, MachineGroups.CanBeDeleted" 
    DeleteCommand="DELETE FROM MachineGroups WHERE MachineGroupID = @MachineGroupID"> 
    <DeleteParameters> 
     <asp:Parameter Name="MachineGroupID" /> 
    </DeleteParameters> 
</asp:SqlDataSource>
