I have a business object called Companies which contains a list of Department objects each of which contains list of Employee objects.

On a form I have a combobox to display the companies, combo box to display the departments, and finally a list box to display the employees.

I created a data provider for the companies which the Companies combobox displays. Is it possible, without using event handlers for selection changed, to bind the department combobox with the "Selected" company.Departments and the Employee combobox with the "Selected" department.Employees?

Any clue on how to do this would be appreciated!
