Question

在我的GridView中，我有一份员工列表。当我单击删除链接时，我正在调用一个从两个表中删除信息的存储过程。无论如何，第一个表工作正常。第二个表也可以正常工作，但是，如果最初有超过4行数据与给定的EmployeeID相对应，即使所有数据都按预期删除，它也会返回错误。如果我删除第二个删除语句并保持Cities表原样，我没有收到任何错误，所以它必须与该命令有关。由于第二个表中的数据没有出现在GridView中，我不确定为什么会发生这种情况。有什么想法吗？

存储过程：DeleteUser

DELETE FROM Users WHERE ID=@ID
DELETE FROM Cities WHERE ID=@ID

ASPX

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
    DataKeyNames="ID" DataSourceID="SqlDS1" AllowSorting="True">
    <Columns>
        <asp:CommandField ShowDeleteButton="True" />
        <asp:BoundField DataField="ID" HeaderText="ID" 
            SortExpression="ID" ReadOnly="True" />
        <asp:BoundField DataField="Username" HeaderText="Username" 
            SortExpression="Username" ReadOnly="True" />
    </Columns>
</asp:GridView>
<asp:SqlDataSource ID="SqlDS1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:ConnectionString %>" 
    SelectCommandType="StoredProcedure" SelectCommand="SelectUser" 
    DeleteCommandType="StoredProcedure" DeleteCommand="DeleteUser">
    <SelectParameters>
        <asp:Parameter Name="ID" Type="String" DefaultValue="All" />
    </SelectParameters>
    <DeleteParameters>
        <asp:Parameter Name="ID" Type="String"></asp:Parameter>
    </DeleteParameters>
</asp:SqlDataSource>

另外，我应该提一下，如果我直接在SQL中运行DeleteUser存储过程，则所有内容都会按预期从两个表中删除，并且不会返回任何错误。

我在另一个论坛上发现了一个帖子，其中一个人报告设置了AllowPaging =＆＃34; True＆＃34;解决了这个问题。我不确定为什么这应该重要，虽然我继续前进并做了同样的事情，我的问题也得到了解决。我有兴趣了解解决问题的原因，但至少它现在正在运作。
