帮助 ASP.NET ObjectDataSource

Question

我有一个带有 Load 方法的 User 对象，该方法接受 UserId 参数并将用户数据加载到对象成员变量中。

现在我想做的是使用ObjectDataSource 将此数据加载到DetailsView 控件，但我不知道如何操作。

首先，我不确定我是否已正确设置代码以将参数 (UserID) 传递给SelectMethod (cUser.Load)。其次，我不知道如何将这些数据加载到DetailsView，因为我实际上并没有从Load 方法返回结果，我只是用数据加载对象......这是我的代码..

<asp:GridView runat="server" ID="gvUsers" DataKeyNames="UserID" BackColor="#eeeeee"     Width="85%"
                    HorizontalAlign="Center"
                    Font-Bold="True" Font-Names="Verdana"
                    Font-Size="10pt" AutoGenerateColumns="False"
                    OnRowDataBound="GridView1_RowDataBound"
                    OnRowDeleting="GridView1_RowDeleting"
                    OnSelectedIndexChanged="IndexChanged" >
            <HeaderStyle BackColor="Black" ForeColor="White"
                   Font-Bold="True" HorizontalAlign="Center" />
            <SelectedRowStyle BackColor="yellow" ForeColor="blue" />
            <AlternatingRowStyle BackColor="#ffffff" />

                             CommandArgument='<%# Eval("UserID") %>'
                             CommandName="Delete" runat="server">
                             Delete</asp:LinkButton>
                         </ItemTemplate>
                       </asp:TemplateField>
                    </Columns>
              </asp:GridView><br /><br />

                    <asp:CommandField ShowDeleteButton="False" ShowEditButton="True"     ShowInsertButton="True" />
>
                </Fields>
            </asp:DetailsView>
                <asp:ObjectDataSource ID="ObjectDataSource1"
                    runat="server" SelectMethod="Load" TypeName="cUser">
                    <SelectParameters>
                        <asp:ControlParameter ControlID="gvUsers" PropertyName="SelectedValue" Name="iUserID" Type="int32" />
                    </SelectParameters>
                </asp:ObjectDataSource>

有没有办法做我想要实现的目标？如果有，请举例说明吗？

非常感谢。谢谢
