我已经为此工作了一段时间，并意识到我的 DetailsView 本身实际上可以正常工作（我在另一个页面上对其进行了测试）。

但是当我把它放在页面的选项卡布局中，然后单击编辑时，它会在更新时清除数据库中具有空值的所有值。

例如这里的页面：http ://pactlegacy.com/sentinel/employeeprofile.aspx?curEmp=3

这是详细信息视图：

<div id="tab-general" class="tabs-content">

                            <div class="avatar">
                                <h3>General Information</h3>
                            </div>

                            <fieldset class="grey-bg">
                                <legend>Required fields</legend>

                                <div class="colx3-left-double">

                                    <asp:DetailsView ID="DetailsView1" runat="server" Height="50px" Width="125px"
                                        AutoGenerateRows="False" DataKeyNames="ID" DataSourceID="SqlDataSource1">
                                        <Fields>
                                            <asp:CommandField ShowEditButton="True" ButtonType="Button"/>

                                            <asp:BoundField DataField="FirstName" HeaderText="First Name"
                                                SortExpression="FirstName" />
                                            <asp:BoundField DataField="LastName" HeaderText="Last Name"

                                            <asp:BoundField DataField="JobID" HeaderText="JobID" SortExpression="JobID" />
                                            <asp:BoundField DataField="SupervisorID" HeaderText="SupervisorID"
                                                SortExpression="SupervisorID" />
                                            <asp:BoundField DataField="HireDate" HeaderText="Hire Date"

                                    </asp:SqlDataSource> 

                                </div>







                            </fieldset>

                        </div>

有谁知道为什么会这样？为了让我的 DetailsView 在我的选项卡布局中正确更新，我需要更改什么？

您需要在 DetailsView 中添加一个 ID 字段，如下所示：

 <asp:BoundField 
         DataField="ID" 
         HeaderText="ID" 
         InsertVisible="False" 
         ReadOnly="True" 
         SortExpression="ID" />

这是您在 DetailsView 中缺少的主键。
