在gridview中编辑记录，如何利用ObjectDataSource更新 <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
                        DataSourceID="ObjectDataSource1" AllowSorting="True" GridLines="None" 
                        DataKeyNames="ID">
                        <Columns>
                            <asp:TemplateField HeaderText="序号">
                                <ItemTemplate>
                                    <%# Container.DataItemIndex + 1%>
                                </ItemTemplate>
                                <HeaderStyle CssClass="first" Width="50px" />
                                <ItemStyle CssClass="first" Width="50px" />
                            </asp:TemplateField>
                            <asp:TemplateField HeaderText="单位名称" SortExpression="UnitName">
                                <EditItemTemplate>
                                    <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("UnitName") %>'></asp:TextBox>
                                    <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="TextBox1"
                                        ErrorMessage="*" ForeColor="Red">*</asp:RequiredFieldValidator>
                                </EditItemTemplate>
                                <ItemTemplate>
                                    <asp:Label ID="Label1" runat="server" Text='<%# Bind("UnitName") %>'></asp:Label>
                                </ItemTemplate>
                            </asp:TemplateField>
                            <asp:TemplateField HeaderText="排序" SortExpression="SortIndex">
                                <EditItemTemplate>
                                    <asp:TextBox ID="TextBox2" Width="30px" runat="server" Text='<%# Bind("SortIndex") %>'></asp:TextBox>
                                    <asp:CompareValidator ID="CompareValidator1" runat="server" ControlToValidate="TextBox2"
                                        ErrorMessage="*" ForeColor="Red" Operator="DataTypeCheck" Type="Integer">*</asp:CompareValidator>
                                </EditItemTemplate>
                                <ItemTemplate>

                                </ItemTemplate>
                            </asp:TemplateField>
                            <asp:CommandField ShowEditButton="True" />
                                                   </Columns>
                        <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？

Answer 1

你的Bind不就是对应起来了么。

Answer 2

 在哪里对应？PropertyName="？？？？？"
Name="unitName" 这个是写入数据库方法的参数名

Answer 3

UpdateUnitInfo是你自己写的么？DataSourceID="ObjectDataSource1" 是你自己写的么？如果只是重复，你能否完成教程再上csdn问这类问题呢？否则任何社会培训班你都难以毕业。
