I can't simply use the hidden tag, since the server side won't that value belong to which row in my form. Also, hidden tag can't pass in an array form into server, so that all the rows in my form won't be recognize by the processing mechanism from the server
hidden tag can't pass in an array form into server...Very good
That is why you need to develop something that takes the array and makes in a format tat can be passed to the server. Bears idea would have a hidden field in each row that you would update with the new position. Or you take the array, make it into a string and put that value in the hidden element.
