Using IG 12.2, IgniteUI.igGrid...

I have a grid configured to row edit mode and batch updating.  I have turned off the Done and Cancel buttons.

I like the fact that a row's text turns to italics after the user edits a row.

When the user clicks a button to save the edits, I need to do some validation on the entered values before allowing the save.  I'm trying to do this in Javascript by reading values from the grid's datasource

var grid = $('#myGrid');

var ds = grid.data("igGrid").datasource.dataView()

But I find that the datasource doesn't have the values unless I call commit on the grid.  This commit call clears the italics from the text.

When I finish my validation code, if the rules fail, I don't save the edits, but I would like to have the edited row still show italics.  I have tried calling rollback on the grid to no effect.

Is there a better way to get the edited data without commiting on the grid?

Is there a way to reinstate the italics in the case where I don't call savechanges?

Thanks in advance for any suggestions.
