Question

我正在网站上购买购物车，并且我在arraylist中有我的商品（已添加到购物车中）。使用这些值我已经从db中读取了其余的值，并且已成功填充在gridview上。

        if (d1.Read())
        {
            d1.Close();
            sda.SelectCommand = searchResult;
            sda.Fill(dt);
            GridView2.DataSource = dt;
            GridView2.DataBind();
        }

如何在此gridview中添加名为“Quantity”的其他列以及文本框，以便用户可以为gridview中显示的每个项目输入qunatity的值？

非常感谢任何帮助/建议/链接。

感谢，

您可以添加模板字段并将文本框放在ItemTemplate中：

<asp:TemplateField>
            <ItemTemplate>
                <asp:TextBox ID="TextBox1" runat="server" Text=""></asp:TextBox>
            </ItemTemplate>
        </asp:TemplateField>

[编辑]这是一个更完整的网格：

<asp:GridView ID="GridView1" runat="server">
    <Columns>
        <asp:BoundField />
        <asp:BoundField />
        <asp:TemplateField>
            <ItemTemplate>
                <asp:TextBox ID="TextBox1" runat="server" Text=""></asp:TextBox>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

请注意，只要我决定将其放在列列表中，TemplateField就会显示出来。如果这仍然不适合你，你可以发布你的GridView标记，这样我就可以看到你有什么？

[编辑2]这是您网格的更新版本。您只需要设置BoundFields以绑定到您需要的数据集中的任何值。

<asp:GridView ID="GridView2" runat="server" BackColor="#388AD0" BorderColor="Black"
    BorderStyle="Solid" BorderWidth="1px" CellPadding="3" ForeColor="Black" GridLines="Vertical"
    Height="160px" Style="left: 72px; position: relative; top: 8px" Width="504px"
    AllowPaging="True" PageSize="5">
    <Columns>
        <asp:BoundField />
        <asp:BoundField />
        <asp:TemplateField>
            <ItemTemplate>
                <asp:TextBox ID="TextBox1" runat="server" Text=""></asp:TextBox>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
    <FooterStyle BackColor="#E0E0E0" />
    <PagerStyle BackColor="Silver" ForeColor="Black" HorizontalAlign="Center" />
    <SelectedRowStyle BackColor="#388AD0" Font-Bold="True" ForeColor="White" />
    <HeaderStyle BackColor="Black" Font-Bold="True" ForeColor="White" />
    <AlternatingRowStyle BackColor="#388AD0" />
    <PagerSettings Mode="NextPrevious" />
</asp:GridView>
