我正在使用列表视图，请告诉我如何从列表视图模板中选择特定项目。在列表视图模板中，我使用了一个名为“添加到购物车”的按钮。以及如何将产品添加到购物车页面。

    <asp:ListView ID="ListView1" runat="server" DataSourceID="SqlDataSource1" 
    GroupItemCount="5">
    <AlternatingItemTemplate>
        <td runat="server" style="background-color:#FFF8DC;">
            <asp:Image ID="Image2" runat="server" Height="101px" 
                ImageUrl='<%# Eval("img") %>' Width="100px" />
            <br />
            Title:
            <asp:Label ID="titleLabel" runat="server" Text='<%# Eval("title") %>' />
            <br />author:
            <asp:Label ID="authorLabel" runat="server" Text='<%# Eval("author") %>' />
            <br />publisher:
            <asp:Label ID="publisherLabel" runat="server" Text='<%# Eval("publisher") %>' />
            <br />price:
            <asp:Label ID="priceLabel" runat="server" Text='<%# Eval("price") %>' />
            <br />
            <asp:Button ID="Button4" runat="server" Text="Add to Cart" 
                OnClick="Button4_Click" PostBackUrl="~/ShoppingCart.aspx" />
            <br />
        </td>
    </AlternatingItemTemplate>

将 Command 与 Button 和 Listviews ItemCommand 事件一起使用。

页面：

<asp:ListView ID="ListView1" runat="server" DataSourceID="AccessDataSource1" 
    GroupItemCount="3"  ItemPlaceholderID="itemPlaceholder" DataKeyNames="Id">

  <asp:Button ID="cartbtn" Text="Add To cart" runat="server" ForeColor="Blue" Font-Underline="true" CommandName="Add" ></asp:Button>

    </ListView>

在后面的代码中：

      protected void ListView1_ItemCommand(object sender, ListViewCommandEventArgs e)
    {       
        if (e.CommandName.ToString()=="Add")
        {
           //Write your code Here
        }
    }
