thanks Brian, your reply made me try the js bind again*, and this time i managed to make it work... well, sort of...
* = i have tried it before but gave up after a lot of js and ajax debugger errors... i was just not passing the data to my grid properly. i have corrected and added a few lines of js and it works - it does populate the grid with data AND populates my div with totalrecords - BUT... it also always pops up an annoying 'CFGRID: Response is empty' alert!!! if i use ?cfdebug, it does not pop the alert up (but does log it in debugger)... it also keeps popping up same alert when i try re-sorting the grid by clicking on column headers AND when i use the pagination controls!!! and that's when the data is in the grid already! what can i do??? how can i make it NOT mind the absence of response/data? or how can i suppress/disable this pop-up alert? i have tried bindonload=false with another ajaxonload() call to refresh the grid and all sorts of combinations of the two, i have tried adding a row to the grid with <cfgridrow...> nothing worked so far... any ideas? really appreciate all the help.
