WPF中动态实体数据的属性失效的处理方法

WPF的datagrid 不能直接支持动态实体数据的属性设置，很让人郁闷。要知道这意思着，我们要写好多代码在前台去绑定，在后台去写事件。翻遍了网络也没找到好的解决方式，最后只好自己动手了，希望也能帮助到别人。

MainWindow.xaml:

 x:Class="DataGridDisplayNameTest.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525"
        xmlns:dg="clr-namespace:System.Windows.Controls;assembly=PresentationFramework">
    
       x:Name="theGrid" AutoGenerateColumns="True" AutoGeneratingColumn="dg_AutoGeneratingColumn">
