如何在DataGrid绑定中指定对象？我的数据网格有 ItemsSource="{Binding Source=TripsCollection}" 和 AutoGenerateColumns="False" ，列设置为：
<DataGrid.Columns>
<DataGridTextColumn Header="ID" Binding="{Binding TripID}" IsReadOnly="True"></DataGridTextColumn>
...
</DataGrid.Columns>
但有错误：
System.Windows.Data错误：40：BindingExpression路径错误：'对象'''Char'（HashCode = 7209070）'上找不到'TripID'属性 . BindingExpression：路径= TRIPID; DataItem ='Char'（HashCode = 7209070）; target元素是'TextBlock'（Name =''）; target属性是'Text'（类型'String'） .
如何将对象设置为Trip对象？
DataContext类：
private ObservableCollection<Trip> _tripsCollection;
public ObservableCollection<Trip> TripsCollection
{
get { return _tripsCollection; }
set { _tripsCollection = value; NotifyPropertyChanged("TripsCollection"); }
}
旅行课：
[Table(Name="Trips")]
public class Trip
{
private uint _tripID;
private string _start;
private string _end;
private DateTime _date;
private double _length;
private string _note;
private uint _carID = 0;
private EntityRef<Car> _Car;
..and properties for this fields..
}
设置DataContext
public MainWindow()
{
InitializeComponent();
string connString = @"Data Source=.\SQLEXPRESS; Integrated security=SSPI; Connect Timeout=30"; // User Instance=True";
conn = new SqlConnection(connString);
conn.Open();
LogBookViewModel lbvm = new LogBookViewModel(conn);
DataContext = lbvm;
}
