windows forms datagridview example with add new record, update, delete

Does any one know a book or a website with a good tutorial example that shows the following?

A windows forms application (either using C# or VB) that uses sql server table.

It could be using the Northwind database and the Employees table from this database.


So the windows forms shows different employees in a ComboBox control.

When I select one employee then it shows the table columns for that employee in a datagridview.

So the datagridview allows add new employee, update, delete.
