WPF MVVM DataGrid查看SelectedCellsChanged

我是新来的WPF MVVM。我想知道如何检测ViewModel中的SelectedCellsChanged事件。没有任何方法可以在没有将任何代码放入代码背后的代码的情况下检测该事件。这是我的代码。WPF MVVM DataGrid查看SelectedCellsChanged

MainWindow.xaml

<Window x:Class="WpfApplication1.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" 
    DataContext="{StaticResource CusVM}"> 

<Grid> 
    <Button x:Name="myButton" Command="{Binding MyButtonClickCommand}" Width="100" Height="50" Content="click" Margin="0,10,417,260" /> 
    <Label Content="{Binding Name}" Margin="105,37,23,251" /> 
    <TextBox x:Name="inputBox1" Width="200" Height="30" Margin="22,74,295,216" Text="{Binding Text1, UpdateSourceTrigger=PropertyChanged}" /> 
    <TextBox Width="200" Height="30" Margin="263,74,54,216" /> 
    <ComboBox HorizontalAlignment="Left" Margin="122,10,0,0" VerticalAlignment="Top" Width="236" ItemsSource="{Binding Addresses}" SelectedItem="{Binding SelectedAddress}" DisplayMemberPath="AddressLine1" > 

    </ComboBox> 
    <DataGrid Margin="0,109,0,10" ItemsSource="{Binding Addresses}"/> 
</Grid>

视图模型：CustomerViewModel

namespace WpfApplication1.ViewModels 
{ 
    public class CustomerViewModel : EventBase 
    { 
    public ICommand MyButtonClickCommand 
    { 
     get { return new DelegateCommand(FuncToCall, FuncToEvaluate); } 
    } 

    private Address selected_address; 

    public Address SelectedAddress 
    { 
     get { return selected_address; } 
     set { selected_address = value; OnPropertyChanged("SelectedAddress"); Name = value.AddressLine1; } 
    } 

    IEnumerable<Address> addresses = new List<Address>(); 

    public IEnumerable<Address> Addresses 
    { 
     get { return addresses; } 
     set 
     { 
      addresses = value; 
      OnPropertyChanged("Addresses"); 

     } 
    } 
    public CustomerViewModel() 
    { 
     fillList(); 
    } 
    private void fillList() 
    { 
     List<Address> addr = new List<Address>(); 
     addr.Add(new Address() { AddressID=1, AddressLine1="test1"}); 
     addr.Add(new Address() { AddressID=2, AddressLine1="test2"}); 
     addr.Add(new Address() { AddressID = 3, AddressLine1 = "test3" }); 
     addresses = addr; 
    } 


    private string text1; 

    public string Text1 
    { 
     get { return text1; } 
     set { 
      text1 = value; 
      OnPropertyChanged("Text1"); 
      Name = text1; 
     } 
    } 



    private string name; 

    public string Name 
    { 
     get { return name; } 
     set { 
      name = value; 
      OnPropertyChanged("Name"); 
     } 
    } 

    private void FuncToCall(object context) 
    { 
     Name = "test result"; 
    } 

    private bool FuncToEvaluate(object context) 
    { 

     return true; 
    } 


} 
}
