无法在我的gridview上“启用编辑”

我正在尝试将gridview连接到LinqDataSource以选择,更新,插入和删除记录。我能够进入编辑模式并取消编辑模式,但是当我点击更新时没有任何反应。

我发现网上有一些内容可以检查gridview智能标记中的“启用编辑”框,但是当我进入智能标记时,出现的唯一复选框是:启用分页,启用排序和启用选择。其他人没有出现。任何人都看到我在下面做的事情有问题吗?

  <asp:GridView   ID="gv_Personnel" 
                    runat="server" 
                    OnRowDataBound="gv_Personnel_DataBind"
                    AutoGenerateColumns="False" 
                    ShowFooter="True" 
                    DataKeyNames="BudgetLineID"
                    AutoGenerateEditButton="True" 
                    AutoGenerateDeleteButton="True" 
                    DataSourceID="lds_Personnel"
                    >

您是否在不使用匿名类型的情况下尝试了?在代码中,您无法更新anon。数据库中的类型......

看起来这是因为我在LinqDataSoruce上设置了Select值。请参阅以下更新的LDS:

<asp:LinqDataSource ID="lds_Personnel" runat="server" 
    ContextTypeName="nrm.FRGPproposal.FrgpropDataContext" 
    TableName="BudgetLines" 
    Where="ProposalID == @PropNumber &amp;&amp; BudgetLineTypeCode == @BudgetLineTypeCode" 
    EnableDelete="True" EnableInsert="True" EnableUpdate="True">
    <WhereParameters>
        <asp:SessionParameter Name="PropNumber" SessionField="PropNumber" Type="Int32" />
        <asp:Parameter DefaultValue="S" Name="BudgetLineTypeCode" Type="Char" />
    </WhereParameters>
</asp:LinqDataSource>
