When i want to add new i click new on the MaintenanceFormToolStrip  , which puts the controls bound to the parent bo in editable state. When i am entering values in the third control the bo suddenly navigates to next record and the state of the row changes from added to unchanged and then to modified. And the controls are filled with the next record values.When the BO navigates to the next record it does not invoke any events(navigating or navigated).
