can not update more than 1 row at a time

my client side dataprocessor set up is as follows:

var dp = new dataProcessor(“getSQLDatav10.asp”);
dp.setTransactionMode(“POST”, true);
dp.setUpdateMode(“off”);
dp.init(mygrid);

i have a button to send the data on the client side

if I update one row at a time it works fine.

if I try to update more than one row then the rows get marked (bolded) that they are to be updated but nothing happens when I send data.

My guess is that I am not parsing the data correctly when it receives the info from the grid and therefore does not return the proper response to the grid.

any help will be greatly appreciated.

thanks.
