如果您能帮助解决我的代码遇到的一些问题，我将不胜感激. 我正在使用实体框架模型.在LINQ的帮助下，我正在尝试在单个查询中加载实体及其关联的数据(即实现急切的加载). 这是隐藏的代码:

I will appreciate it if you help me with some problems I encountered with my code. I am working with the Entity Framework model. With the help of LINQ, I am trying to load entities and their associated data in a single query (i.e. to implement eager loading). Here''s the code-behind:

protected void btn5_Click(object sender, EventArgs e) { using (EStoreEntities ctx5 = new EStoreEntities()) { var query =(from o in ctx5.Order_Details.Include("Order") select o); //Order-navigation property tb5.Text = (queryas ObjectQuery).ToTraceString(); gv5.DataSource = query; gv5.DataBind(); } }

我正在使用以下ASP代码:

I''m using the following ASP code:

<asp:Button ID="btn5" runat="server" Text="Button" onclick="btn5_Click" /> <asp:GridView ID="gv5" runat="server"></asp:GridView> <asp:TextBox ID="tb5" runat="server" TextMode="MultiLine"></asp:TextBox>

如何修复代码以使Order表内容显示在GridView控件中? 预先谢谢您.
