显示嵌套的匿名类型 [英] displaying nested anonymous type

问题描述

如果您能帮助我解决问题，我将不胜感激.我试图在GridView控件中显示嵌套的匿名类型.但是GridView控件仅显示OrderID和OrderDate字段(即它不显示嵌套类型).
我正在使用以下代码:

I would be grateful if you could help me to solve the problem. Im trying to display a nested anonymous type in a GridView control. But the GridView control displaying only OrderID and OrderDate fields (i.e. it doesn''t display nested type).
I''m using the following code:

protected void btn2_Click(object sender, EventArgs e)
                   {
                      var query = (from o in ctx2.Orders 
                                      select new 
                                      {o.OrderID, o.OrderDate,
                                         nest_anon = new {          
                                             o.Customer,
                                             o.ShipAddress,
                                              o.Status }});
 tb2.Text = (query as ObjectQuery).ToTraceString(); 
 gv2.DataSource=query;
 gv2.DataBind();

我应该在代码中解决什么才能在GridView中显示匿名和嵌套的匿名类型?预先谢谢您.

推荐答案

好，现在我明白了您的意思.

您所要做的就是将gridview的AutoGenerateColumns属性设置为false.然后应用列模板.您需要在这一行上编辑aspx.

ok, now I get what you mean.

All you have to do is set the AutoGenerateColumns property of the gridview to false. Then apply a column templates. You need to edit your aspx on this one.

<asp:GridView ID="grdMain" runat="server" AutoGenerateColumns="False">
  <columns>
    <asp:BoundField DataField="OrderID" HeaderText="OrderID" />
    <asp:BoundField DataField="OrderDate" HeaderText="OrderDate" />
    <asp:BoundField DataField="nest_anon" HeaderText="Nested Type" />
  </columns>
</asp:GridView>

我不确定您要做什么，您是否尝试过:

I''m not really sure what you''re trying to do, have you tried:

gv2.DataSource = query.ToList();
