代码如下:
<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AllowSorting="True"
            AutoGenerateColumns="False" CssClass="table001" DataKeyNames="sortsid" DataSourceID="SqlDataSource1"

                            Display="Dynamic" ErrorMessage="请使用数字" ValidationExpression="^[0-9]{1,}$"></asp:RegularExpressionValidator>
                    </EditItemTemplate>
                    <ItemTemplate>
                        <asp:Label ID="Label1" runat="server" Text='<%# Eval("sortsorder") %>'></asp:Label>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:CommandField ShowDeleteButton="True" ShowEditButton="True" />
            </Columns>
            <RowStyle CssClass="table002" Height="20px" HorizontalAlign="Center" />
            <HeaderStyle CssClass="table002" Height="20px" HorizontalAlign="Center" />
        </asp:GridView>
        <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:527ConnectionString %>"
            DeleteCommand="DELETE FROM [sortslink] WHERE [sortsid] = @sortsid" InsertCommand="INSERT INTO [sortslink] ([categoryid], [webname], [linkaddress], [linklogo], [sortsintroduce], [sortsorder], [linktype], [sh], [addtime], [linkalt]) VALUES (@categoryid, @webname, @linkaddress, @linklogo, @sortsintroduce, @sortsorder, @linktype, @sh, @addtime, @linkalt)"

            <DeleteParameters>

            </UpdateParameters>
            <InsertParameters>
                <asp:Parameter Name="categoryid" Type="Int32" />

                <asp:Parameter Name="sh" Type="Boolean" />
                <asp:Parameter Name="addtime" Type="DateTime" />
                <asp:Parameter Name="linkalt" Type="String" />
            </InsertParameters>
        </asp:SqlDataSource>这里我知道搞:
 <asp:TemplateField HeaderText="排序号">
                    <EditItemTemplate>
                        <asp:TextBox ID="TextBox1" runat="server" Text='<%# Eval("sortsorder") %>'></asp:TextBox>
可是更新的时候值为空了.传不过去,怎么搞好呢?

Answer 1

也就是一更新之后这列的值更新成空了.<asp:Parameter Name="sortsorder" Type="Int32"  Direction="Input"/>
这个应是:.<asp:Parameter Name="sortsorder" Type="Int32"/>
[sortsorder] =sortsorder这个就是:[sortsorder] =@sortsorder
这个写错了.不好意思.帮帮忙呀
