How to refresh a WPF DataGrid?

wpf data-binding datagrid

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 programatically 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?
