首先Model层，建立实体Menu

public 
class Menu
   {
      public
int ID
      {
          get;
          set;
      }
      public
string ClassName
      {
          get;
          set;
      }
      public
int ParentID
      {
          get;
          set;
      }
      public
int OrderID
      {
          get;
          set;
      }
   }

然后再建立Menu的集合类Menus

public 
class Menus
   {
       public
List<Menu> menu;
       public
List<Menu> getMenu()
       {
           menu =
new List<Menu>{
               new
Menu{ID=1,ClassName="菜单1",ParentID=0,OrderID=1},
               new
Menu{ID=2,ClassName="菜单2",ParentID=0,OrderID=2},
               new
Menu{ID=3,ClassName="菜单3",ParentID=0,OrderID=3}
           };
           return
menu;
       }
   }

接着View层，建立MenuPage.xaml页面

<DataGrid AutoGenerateColumns="True"  
ItemsSource="{Binding Human}"
SelectedItem="{Binding GetOne,Mode=TwoWay}"
HorizontalAlignment="Left"  
Name="dataGrid1"
>
            
       </DataGrid>
       <TextBox Text="{Binding GetOne.ID,Mode=OneWay}"
Height="23" 
HorizontalAlignment="Left" 
Margin="247,149,0,0" 
Name="textBox1" 
VerticalAlignment="Top" 
Width="120" 
/>
       <TextBox Text="{Binding GetOne.ClassName,Mode=OneWay}"
Height="23" 
HorizontalAlignment="Left" 
Margin="247,191,0,0" 
Name="textBox2" 
VerticalAlignment="Top" 
Width="120" 
/>

最后ViewModel层，建立MenuViewModel类

public 
class MenuViewModel : INotifyPropertyChanged
   {
       public
event PropertyChangedEventHandler PropertyChanged;
       public
List<Menu> Human { get;
set; }
       private
Menu _getOne;
       public
Menu GetOne
       {
           get
{ return 
_getOne; }
           set
           {
               _getOne = value;
               if
(PropertyChanged != null)
               {
                   PropertyChanged(this,
new PropertyChangedEventArgs("GetOne"));
               }
           }
       }
       public
MenuViewModel()
       {
           Human =
new Menus().getMenu();
       }　　　　
   }
