Kendo Grid proper way of clearing a cell content in an event

If you're using In-Cell editing, this answer is not correct.  Yes model.set() is the proper way to update a model field, but any change to the model field that's being saved in the "save event", will be discarded by the grid.  It seems the Save event is not designed to let you alter the value of the field that's being saved. Changes to other model fields in the save event will work.

Assuming the field is type string and you are using the default editor put in place by the grid, is there a way to alter the value of the model field being saved, and inside the save event?

There's the dataSource change event and checking for action == "itemchange".  Is that the only way to do it?

Thanks.

Thank you.  I should have mentioned that I also use the dataSource "requestStart" event, and if dataSource.hasChanges() reports yes, I prompt the user to save or not.  Regardless of the user choosing OK or cancel, I let the new request continue, but if they choose OK, then I call dataSource.sync().  This lets the changes get saved and then the new request complete (like paging/sorting/filtering on server-side).

When using this technique, calling e.preventDefault() in the grid's save event *does* work and let the screen and model be updated, but when the new requestStart happens, it does not detect any "dirty" rows.

By using the dataSource's change event and checking e.action === "itemchange" && e.field === my field, and using model.set() there, then grid detects a change when the new request starts.
