data binding - How to refresh a WPF DataGrid?

Question

I have a WPF DataGrid with some data. You can add rows through a separate window. The DataContext is the same, a LINQ-to-SQL object. Binding is also the same, I bind the ItemsSource property to a table.

In the other window, when the user clicks on Save, I create a row programmatically and add it using InsertOnSubmit. After that I use the DataContext's SubmitChanges method.

My problem is that the DataGrid isn't updated. If I restart the application I can see the new row, so it's in the database, but I couldn't find a way to refresh the DataGrid.

So far I've tried to use UpdateTarget on the BindingExpression of the DataGrid, but it didn't help. I've also tried dataGrid.Items.Refresh() — same result. How can I fix this?
