jQuery Grid Plugin - jqGrid

Hi there.  I used the grid and the select row function to update another part of a web page where there is extensive data processing options.  So there are one or two buttons that I would like to kick off a process where either the grid reloads but retains the page it was on and the row that was selected OR being able to just update the values in the one or two cells that were updates via javascript calls from the other form.  What do you guys recommend?
