save all Grid

I want save all the grid in the database. Its posible ? not only the changes?

myDataProcessor = new dataProcessor(save.php); //lock feed url
myDataProcessor.setTransactionMode(“POST”,true); //set mode as send-all-by-post
myDataProcessor.setUpdateMode(“off”); //disable auto-update

myDataProcessor.init(myGrid); //link dataprocessor to the grid

myDataProcessor.sendData();

You may mark all your rows as “updated”, so all of them will be sent to server:
dp.setUpdated(row_id, “updated”);
