Question

我在gridview中有一个名为status的字段我想要它，这样当用户点击gridview在textfield的位置更新时，会有一个带已发布和未发布选项的下拉列表。这是代码

        <asp:GridView ID="GridView1" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" DataKeyNames="Id" DataSourceID="SqlDataSource3">
            <Columns>
                <asp:CommandField ShowDeleteButton="True" ShowEditButton="True" />
                <asp:BoundField DataField="name" HeaderText="name" SortExpression="name" />
                <asp:BoundField DataField="info" HeaderText="info" SortExpression="info" />
                <asp:BoundField DataField="productcode" HeaderText="productcode" SortExpression="productcode" />
                <asp:BoundField DataField="status" HeaderText="status" SortExpression="status" />
                <asp:BoundField DataField="price" HeaderText="price" SortExpression="price" />
            </Columns>
        </asp:GridView>
        <asp:SqlDataSource ID="SqlDataSource3" runat="server" ConnectionString="<%$ ConnectionStrings:DefaultConnection %>" DeleteCommand="DELETE FROM [product_tbl] WHERE [Id] = @Id" InsertCommand="INSERT INTO [product_tbl] ([Id], [subcat], [name], [info], [brandid], [gender]) VALUES (@Id, @subcat, @name, @info, @brandid, @gender)" SelectCommand="SELECT * FROM [product_tbl]" UpdateCommand="UPDATE [product_tbl] SET [subcat] = @subcat, [name] = @name, [info] = @info, [brandid] = @brandid, [productcode] = @productcode, [gender] = @gender WHERE [Id] = @Id">
            <DeleteParameters>
                <asp:Parameter Name="Id" Type="Int32" />
            </DeleteParameters>
            <InsertParameters>
                <asp:Parameter Name="Id" Type="Int32" />
                <asp:Parameter Name="subcat" Type="Int32" />
                <asp:Parameter Name="name" Type="String" />
                <asp:Parameter Name="info" Type="String" />
                <asp:Parameter Name="brandid" Type="Int32" />
                <asp:Parameter Name="gender" Type="Int32" />
            </InsertParameters>
            <UpdateParameters>
                <asp:Parameter Name="subcat" Type="Int32" />
                <asp:Parameter Name="name" Type="String" />
                <asp:Parameter Name="info" Type="String" />
                <asp:Parameter Name="brandid" Type="Int32" />
                <asp:Parameter Name="productcode" Type="Int32" />
                <asp:Parameter Name="gender" Type="Int32" />
                <asp:Parameter Name="Id" Type="Int32" />
            </UpdateParameters>
        </asp:SqlDataSource>

对于下拉列表，您需要放置templatefield

             <asp:TemplateField HeaderText="Status">
                    <EditItemTemplate>
                        <asp:DropDownList ID="ddlStautus" runat="server"> 
                           <asp:ListItem>published</asp:ListItem>
                           <asp:ListItem>unpublished</asp:ListItem>
                        </asp:DropDowList>
               </asp:TempLateFeild>

并将您的gridview绑定在
