  <   asp：超链接    ID   =  ModelLabel    href   =  Details.aspx    runat   =  server   文字  ='  <％ #Eval（ 模型）％> '      /  >  
 <   br     /  >  
 <   br     /  >  
 <   / ItemTemplate  >  
 <  < span class =code-leadattribute> / asp：DataList  >  

解决方案

在 SelectedIndexChanged 内事件，获取所选行并将一些键值作为 QueryString 参数传递给下一页。



On下一页，阅读 QueryString 值并从 DataSource 获取必要的详细信息并绑定的DetailsView

<asp:DataList ID="DataList1" runat="server" DataKeyField="Model" DataSourceID="SqlDataSource1" RepeatColumns="5" RepeatDirection="Horizontal" Cellpadding="10" CellSpacing="10" GridLines="Horizontal" OnSelectedIndexChanged="DataList1_SelectedIndexChanged">
        <ItemTemplate>
            <asp:Label ID="BNameLabel" runat="server" Text='<%# Eval("BName") %>' />
            <br />
            <asp:Image ID="MImage" runat="server" Image='<%# Eval("MImage") %>' Height="150px" Width="100px" />
            <br />
            <asp:Hyperlink ID="ModelLabel" href="Details.aspx" runat="server" Text='<%# Eval("Model") %>'  />
            <br />
            <br />
        </ItemTemplate>
    </asp:DataList>

解决方案

Inside the SelectedIndexChanged Event, get the selected row and pass some key value to the next page as a QueryString Parameter.

On next page, read the QueryString value and get the necessary details from the DataSource and bind the DetailsView.
