DetailsView更新

Question

我有一个显示所有注册用户及其部分信息的GridView，当您选择边上的"select“链接时，它会显示一个包含与该用户相关的所有详细信息的DetailsView。select可以很好地工作，并更新所选用户的详细信息视图，当我尝试编辑DetailsView时，它将更新数据库，并在更改字段时填写为所有用户更新的信息(例如，如果我更改客户的名字，每个注册的人都会得到这个名字)。下面是我的SqlDataSource的aspx代码：

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
        ConnectionString="<%$ ConnectionStrings:ApplicationServices %>" OldValuesParameterFormatString="original_{0}" 
        SelectCommand="SELECT * FROM [UserProfile] ORDER BY [Email], [LastName], [Company]"
        UpdateCommand="UPDATE [UserProfile] SET [LastName] = @LastName, [PartsList] = @PartsList, [UserName] = @UserName, [Question] = @Question, 
                      [Answer] = @Answer, [Role] = @Role 
                      WHERE [FirstName] = FirstName AND [Company] = Company">
            <UpdateParameters>
                <asp:Parameter Name="FirstName" Type="String" />
                <asp:Parameter Name="LastName" Type="String" />
                <asp:Parameter Name="Company" Type="String" />
                <asp:Parameter Name="PartsList" Type="String" />
                <asp:Parameter Name="UserName" Type="String" />
                <asp:Parameter Name="Password" Type="String" />
                <asp:Parameter Name="Email" Type="String" />
                <asp:Parameter Name="Question" Type="String" />
                <asp:Parameter Name="Answer" Type="String" />
                <asp:Parameter Name="Role" Type="String" />                    
            </UpdateParameters>
    </asp:SqlDataSource>

Answer 1

您在Where参数中忘记了@original_

将UpdateCommand更改为：

UPDATE [UserProfile] SET [LastName] = @LastName, [PartsList] = @PartsList, [UserName] = @UserName, [Question] = @Question, [Answer] = @Answer, [Role] = @Role WHERE [FirstName] = @original_FirstName AND [Company] = @original_Company
