I have a relationship between Members and Dues. It is a one to many relationship. I populate the ItemsSource of my grid with Member.Dues, and it displays properly in the gird. When I add a row to the Dues table after the user clicks the Add button on the grid how do I tell the UI to refresh the data binding to show the new row in the grid. If I quit the form and come back in it shows properly.
If I were using an ObservableCollection called Dues I would just inherit from INotifyProperyChanged class.
What do I do when using relationships?
