I have two datagridviews (parentDatagridview and childDatagridView). The parentDatagridview datasource is Bindingsource1 and childDatagridview datasource is Bindingsource2. Thanks to jmcilhinney for the Master/Detail code.

The form is used to monitor transactions of users (no add, edit and deletes). The parentDatagridview is a listing of Users and the childDatagridview is a listing of user transactions.

Question: I will have a refresh button that will refresh the childDatagridview to see if there where transactions added to a user. How do I refresh the bindingsource2?

Any help is highly appreciated.
