求助，我想在DetailsView中新建记录时，应该如何获得该该控件的值。

如图：点击新建之后:如何获得该控件的值？我用的是FindControl   但是不知道该控件的ID是多少。文件源代码如下：<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %><!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    
    </div>
        <asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateInsertButton="True" AutoGenerateRows="False" Height="50px" OnItemInserting="DetailsView1_ItemInserting" OnModeChanging="DetailsView1_ModeChanging" OnPageIndexChanging="DetailsView1_PageIndexChanging" Width="125px">
            <Fields>
                <asp:BoundField DataField="ID" HeaderText="编号" />
            </Fields>
        </asp:DetailsView>
    </form>
</body>
</html>
