Question

我正在为自行车商店创建一个网站，其中应该有两排自行车（图像和文字）并排在页面上。我试图在gridview中有2行，其中数据是从XML文件填充的。我遇到的问题是每行包含与旁边的数据相同的数据。有谁知道我怎么能解决这个问题 - 即。每行都有新数据？我从来没有使用过gridview或XML文件，所以如果这很明显就道歉了！

 <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
 DataSourceID="XmlDataSource1" AllowSorting="True"  HorizontalAlign="Center"
 Width="800px" AllowPaging="True" AllowCustomPaging="True" GridLines="None">
 <Columns>

    <asp:TemplateField>
        <ItemTemplate>
            <asp:Label ID="ProductName" 
                       runat="server" 
                       Text='<%# XPath("ProductName") %>'></asp:Label>

            <asp:Label ID="ProductDescription" 
                       runat="server" 
                       Text='<%# XPath("Description") %>'></asp:Label>
            <asp:Label ID="Cost" 
                       runat="server" 
                       Text='<%# XPath("Cost") %>'></asp:Label>
            <asp:Image ID="Image1"
                       runat="server" Height="200px" 
                       ImageUrl='<%# XPath("Image") %>' 
                       Width="200px" Align="left"/>
        </ItemTemplate>


    </asp:TemplateField>

       <asp:TemplateField>
        <ItemTemplate>

我对你的建议是不要让你自己处理XML复杂性。

如果您的XML在数据库中，请阅读以下主题：How to loop and parse xml parameter in sql server stored procedure。

如果您的XML在您的计划中，请阅读以下主题：load xelement into a datatable

选择数据后，您可以使用Eval代替XPath，我希望您的问题会被删除

在asp.net中将XML文件中的数据填充到gridview中的行中
