WPF Toolkit datagrid /doesn’t refresh data

H I use SQL CE and LINQ. I bind p开发者_JAVA技巧roperty typeof Table on ItemSource of Datagrid control from WPF Toolkit.

Something like this.

    public Table<TestNick>  MySource
    {
        get { return _tab; }
        set
        {
            _tab = value;
            NotifyPropertyChanged("MySource");

        }
    }


    <Controls:DataGrid Name="Dg" 
                       ItemsSource="{Binding Path=MySource, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}"
                       Grid.Row="0"/>

I retrieve data from DB with LINQ:

        const string connStr = @"Spiri_SQL_CE_DB.sdf";
        _dc = new Spiri_SQL_CE_DB(connStr);
        MySource = _dc.TestNick;

If I add a breakpoint on last line I see all values from tables TestNick, but it doesn’t load this data in DataGrid.

What is bad?

EDITED:

I check the ItemSource of DataGrid control in code behind, the item source is correct but I see in DataGrid (view) "old data".

So binding must be correct, problem is that DataGrid control doesn’t refresh data.

• Make sure datagrid autogeneratecolumns is true
• While running check the output window if there are any binding issues
• Another trick is to put a button on the view and write a code behind function on click of that button to debug whats the datagrid itemsource, if its empty try to invoke viewModel/Model's getDatagridData function and then see if it loads, in case it loads that means your NotifyPropertyChanged is not yet functional
