Have a look at the help file under "Common Business Object Tasks" / "Adding Editing & Deleting Records".
Also, have you gone through the Tutorials "Creating a WinForms App" ? That will give you a general idea of things. After that, studying the StrataFlix Sample will help you a lot too.
And don't worry about making questions, keep on bringing them.
Never the less I m asking:
I ve done the same example as in the video parent-child relationship management and it worked fine, but I tried to reproduced it using a pre defined Form with some text boxes bounded to the CustomerBO and a button where I putt the source with the CustomerBO1.movelast() and CutomerNotesBO1.newrow() and when I "watch" using the VS tool I dont see the new record, but when I look at the table directly it was created as well.
I tryed the same at the new of the form and did the same.
What am I missing.
Regards.
