显示LINQ的结果XML查询中的GridView(Displaying results of a L

我查询在LINQ XML文档并希望显示在gridview的结果，允许用户从列表中选择。

查询是作为用户输入的结果。

下面是我的XML的副本。

你应该能够做到这一点。这里有几样：

http://vstoolsforum.com/blogs/vbnet/archive/2008/08/26/linq-to-xml-with-asp-gridview-in-vb.aspx

它看起来像你的XML是从已保存到XML的数据集。如果是这样的话，你也可以使用此链接中的信息重新加载数据集：

从那里，你可以筛选出数据视图数据集的结果。

您也可以在LINQ的数据集：
