您需要设置DetailsView的DataKeyNames属性，以便DetteParameter从中获取参数值
<asp:DetailsView ID="DetailsView1" runat="server" Height="50px" Width="125px" DataSourceID="SqlDataSource2" DataKeyNames="ID"
        OnItemDeleted="DetailsView1_ItemDeleted" OnItemInserted="DetailsView1_ItemInserted"
        OnItemUpdated="DetailsView1_ItemUpdated">
    <Fields>
        <asp:CommandField ShowDeleteButton="True" />
    </Fields>
</asp:DetailsView>
