在gridview中编辑记录，怎么利用ObjectDataSource更新(3)

                        <RowStyle CssClass="row" />
                                         </asp:GridView>

 <asp:ObjectDataSource ID="ObjectDataSource1" runat="server"                 TypeName="UnitInfo" UpdateMethod="UpdateUnitInfo">
                     <UpdateParameters>
                    <asp:ControlParameter ControlID="GridView1" Name="unitName" 
                        PropertyName="？？？？？" Type="String" />
                    <asp:ControlParameter ControlID="GridView1" Name="sortIndex" 
                        PropertyName="？？？？" Type="String" />
                    <asp:ControlParameter ControlID="GridView1" Name="id" 
                        PropertyName="SelectedDataKey！！！" Type="String" />
                </UpdateParameters>
            </asp:ObjectDataSource>



如何将gridview中文本框中内容和objectdatasource中参数对应起来呢？

你的Bind不就是对应起来了么。
