jQuery Grid Plugin - jqGrid

I have a doubt about form editing.

In the inline editing, before the editing be made, it creates internally an array (savedRow) and fill it with the values of the fields that are being editable, so I can access this values.

I'd like to know if in the form editing it has something similar to this, because I need to access the values of the fields before the editing will be completed to do a validation before the fields are "saved" in the database.

Someone could help me?

Thanks in advance!

Best Regards!
