C# SqLite EntityFramework表更新操作落后一步

如标题所示，当我更新SQLite db中任何表中的记录时，更新“落后一步”

我使用的是datagrid，在

CellEditEnding

事件中，我调用以下方法：

private void CellEdited(object sender, DataGridCellEditEndingEventArgs e)
{
  Marcatore edited = (Marcatore)e.Row.Item;
  MainWindow._DbContext.Entry(edited).State = System.Data.Entity.EntityState.Modified;
  MainWindow._DbContext.SaveChanges();
}

DataGrid的加载方式如下：

private void Windows_Loaded(object sender, System.Windows.RoutedEventArgs e)
{
    dataGrid.ItemsSource = MainWindow._DbContext.Marcatore.ToList();
}

xaml如下所示：

<DataGrid x:Name="dataGrid" AutoGenerateColumns="False" EnableRowVirtualization="True" ItemsSource="{Binding}" RowDetailsVisibilityMode="VisibleWhenSelected" CellEditEnding="CellEdited">
    <DataGrid.Columns>
        <DataGridTextColumn x:Name="idColumn" Binding="{Binding ID}" Visibility="Hidden"/>
        <DataGridTextColumn x:Name="modelColumn" Binding="{Binding Model}" Header="Marker Model" Width="Auto"/>
        <DataGridTextColumn x:Name="comInterfaceColumn" Binding="{Binding ComInterface}" Header="Communication Interface" Width="Auto"/>
    </DataGrid.Columns>
</DataGrid>

我要编辑的表：

[Table(Name = "Marcatore")]
public class Marcatore    
{
    [Column(Name = "ID", IsDbGenerated = true, IsPrimaryKey = true, DbType = "INTEGER")]
    [Key]
    public int ID { get; set; }

    [Column(Name = "Model", DbType = "TEXT")]
    public string Model { get; set; }

    [Column(Name = "ComInterface", DbType = "TEXT")]
    public string ComInterface { get; set; }
}

除了执行两次

Savechanges

之外，还有什么办法解决这个问题吗

public class SQLiteConfiguration : DbConfiguration
{
    public SQLiteConfiguration()
    {
        SetProviderFactory("System.Data.SQLite", SQLiteFactory.Instance);
        SetProviderFactory("System.Data.SQLite.EF6", SQLiteProviderFactory.Instance);
        SetProviderServices("System.Data.SQLite", (DbProviderServices)SQLiteProviderFactory.Instance.GetService(typeof(DbProviderServices)));
    }
}

[Table(Name = "Marcatore")]
public class Marcatore    
{
    [Column(Name = "ID", IsDbGenerated = true, IsPrimaryKey = true, DbType = "INTEGER")]
    [Key]
    public int ID { get; set; }

    [Column(Name = "Model", DbType = "TEXT")]
    public string Model { get; set; }

    [Column(Name = "ComInterface", DbType = "TEXT")]
    public string ComInterface { get; set; }
}
