MVVM数据网格绑定 [英] MVVM datagrid binding

问题描述

我使用的MVVM为我的项目，我想表从我与一个DataGrid绑定数据库。但是当我运行我的应用程序数据网格是空的。

I'm using MVVM for my project and I'm trying to bind a table from my database with a DataGrid. But when I run my application datagrid is empty.

MainWindow.xaml.cs：

 public MainWindow(){
        InitializeComponent(); 
        DataContext = new LecturerListViewModel()
    }

MainWindow.xaml

 <DataGrid AutoGenerateColumns="False" ItemsSource="{Binding Source=Lecturers}" >
            <DataGrid.Columns>
                <DataGridTextColumn Header="Name" Binding="{Binding Name}"/>
                <DataGridTextColumn Header="Surname" Binding="{Binding Surname}"/>
                <DataGridTextColumn Header="Phone" Binding="{Binding Phone_Number}" />
            </DataGrid.Columns>
 </DataGrid>

LecturerListViewModel.cs：

public class LecturerListViewModel : ViewModelBase<LecturerListViewModel> 
{

    public ObservableCollection<Lecturer> Lecturers;
    private readonly DataAccess _dataAccess = new DataAccess();

    public LecturerListViewModel()
    {
        Lecturers = GetAllLecturers();
    }

和ViewModelBase实现INotifyPropertyChanged。

and ViewModelBase implements INotifyPropertyChanged.

Lecturer.cs

public class Lecturer
{
    public Lecturer(){}

    public int Id_Lecturer { get; set; }
    public string Name { get; set; }
    public string Surname { get; set; }
    public string Phone_Number { get; set; }

我做了什么错？我debuger检查，并DataContext中包含了所有的讲师，但是疗法没有在数据网格中。

What did I do wrong? I checked it with debuger and DataContext contains all lecturers, but ther aren't shown in datagrid.

推荐答案

赛义德·萨阿德以上是正确的。我看到你的设置，这两个赛义德解决两个潜在的问题。

Sayed Saad above is correct. I see two potential problems with your setup, both of which Sayed resolves.

1. 张贴在这个问题DOEN的例子不实现INotifyPropertyChanged


2. 的CLR属性绑定到必须是公共财产。字段将不会工作，因为databindindg通过反射的作品。
