如何将数据从xml数据源读取到网页的标准控件中 [英] how to read data from xml datasource into a standard controls of a web page

问题描述

我已经在
下创建了一个xml数据源

i have created a xml datasource as under

<Item>
    <id>Motorola Blackflip</id>
    <Description>Motorola Backflip sports a 3.1-inch HVGA capacitive touchscreen</Description>
    <feature>Touchscreen,Wi-Fi,Bluetooth,5 MP Camera,Android OS</feature>
    <price>Rs.18000</price>
    <image>~/Image/Motorola-Backflip.jpeg</image>
  </Item>

并与数据列表绑定，如下所示

and binded with datalist as under

<asp:DataList ID="DataList1" runat="server" Height="498px" Width="566px"

        BackColor="White" BorderColor="#DEDFDE" BorderStyle="None" BorderWidth="1px"

        CellPadding="4" ForeColor="Black" GridLines="Vertical" RepeatColumns="2"

        onitemcommand="DataList1_ItemCommand">
        <AlternatingItemStyle BackColor="White" />
        <FooterStyle BackColor="#CCCC99" />
        <HeaderStyle BackColor="#6B696B" Font-Bold="True" ForeColor="White" />
        <ItemStyle BackColor="#F7F7DE" />
    <ItemTemplate>
        <asp:ImageButton ID="ImageButton1" runat="server" ImageUrl='<%#Eval("image")%>'

         Height="150" Width="150" CommandName="product" CommandArgument='<%#Eval("image")%>'/><br />
        <asp:LinkButton ID="LinkButton2" runat="server" Text='<%#Eval("Description") %>'

        CommandName="id" CommandArgument='<%#Eval("id") %>'></asp:LinkButton>

    </ItemTemplate>

现在使用冒泡事件，我正在读取数据并重定向到其他页面，如下所示

now using bubbled event i am reading data and redirecting to some other page as shown bellow

protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
    {
        if (e.CommandName == "product")
        {
            Response.Redirect("ViewProduct.aspx?img=" + e.CommandArgument.ToString());
        }
        else
        {
            Response.Redirect("Description.aspx?de=" + e.CommandArgument.ToString());
        }
    }
}

现在，在重定向页面中，我希望将剩余的xml数据保存到某些控件中，例如标签，图像等.
请帮助获取剩余数据.

now in the redirected page i want remaining xml data into some controls like label,image etc.
