detect row changes

Summary:

Content (required):

I have an editable table in which I add editable rows and within the row I can record the data. I have a SAVE button that reads all the lines in the table and sends them to an OIC service. I want to know which of those rows have changed their original values. Is there a way to do that?

I know there is a RowEditEndChain event to save the edit, but that doesn't guarantee if the original values ​​have been changed.
