MVVM Light DataGrid binding - wpf

Question

I'm developing a WPF with C#, .NET Framework 4.5.1, MVVM Light framework and Entity Framework 6.1.3.
I have this DataGrid in a window:
<DataGrid x:Name="LevelConfigurationDataGrid" Grid.Column="1" Grid.Row="1" Margin="20,0" ItemsSource="{Binding LevelConfigs}">
<DataGrid.Columns>
<DataGridTextColumn Binding="{Binding CODE_LEVE}" Header="Nivel"/>
<DataGridTextColumn Binding="{Binding CODE_NAME}" Header="Nombre"/>
<DataGridTextColumn Binding="{Binding IS_ACTIVE}" Header="¿Activa?"/>
<DataGridTextColumn Binding="{Binding CODE_TYPE}" Header="Tipo de código"/>
<DataGridTextColumn Binding="{Binding CODE_SOURCE}" Header="Origen del código"/>
<DataGridTextColumn Binding="{Binding HELPER_CODE_TYPE}" Header="Tipo de Helper Code"/>
<DataGridTextColumn Binding="{Binding HELPER_CODE_SOURCE}" Header="Origen del helper code"/>
<DataGridTextColumn Binding="{Binding QUANTITY}" Header="Cantidad"/>
<DataGridTextColumn Binding="{Binding REMAINING_CODES}" Header="Restantes"/>
<DataGridTextColumn Binding="{Binding TRZ_ENDPOINT}" Header="TRZ IP"/>
<DataGridTextColumn Binding="{Binding TRZ_ENDPORT}" Header="TRZ Puerto"/>
</DataGrid.Columns>
</DataGrid>
And on MainViewModel:
public ObservableCollection<CODE_LEVEL_CONFIGURATION> LevelConfigs
{
get { return m_LevelConfigs; }
set
{
m_LevelConfigs = value;
RaisePropertyChanged("LevelConfigs");
}
}
And on CODE_LEVEL_CONFIGURATION:
public class CODE_LEVEL_CONFIGURATION
{
public byte CODE_LEVEL { get; set; }
public string LEVEL_NAME { get; set; }
public bool IS_ACTIVE { get; set; }
public byte CODE_TYPE { get; set; }
public byte CODE_SOURCE { get; set; }
public byte? HELPER_CODE_TYPE { get; set; }
public byte? HELPER_CODE_SOURCE { get; set; }
public int QUANTITY { get; set; }
public int REMAINING_CODES { get; set; }
public string TRZ_ENDPOINT { get; set; }
public int? TRZ_ENDPORT { get; set; }
public virtual ICollection<CODES> Codes { get; set; }
public virtual ICollection<HELPER_CODES> HelperCodes { get; set; }
}
But, when I load the data on DataGrid I get more columns that I have defined on XAML. I get my columns and 13 columns more (on for each CODE_LEVEL_CONFIGURATION property).
What am I doing wrong?

Try setting AutoGenerateColumns to False
<DataGrid x:Name="LevelConfigurationDataGrid" AutoGenerateColumns="False"
Grid.Column="1" Grid.Row="1" Margin="20,0" ItemsSource="{Binding LevelConfigs}">
<DataGrid.Columns>
...
</DataGrid.Columns>
</DataGrid>
