I am trying to fill a Grid periodically (could take a whole day), but I cant decide what method of dhtmlx to use without overloading the browser, and to have the opportunity to pause/continue the process.
In other words, I’m trying to establish a two-way channel between Grid-Server, to maintain continues data flow, yet controllable.
I am wondering if I use Ajax, the Callback func is called from an async call (get/post) every time data (txt,xml) send or after the called php return (terminates) ?
Or, is there any alternative to this?
Thanks in advance,
JL

It will be called when connection closed ( after php return )
>>I’m trying to establish a two-way channel between Grid-Server
Browser has built in limitation on connection live time, so you wouldn’t be able to use same connection longer that default timeout time ( about 5 minutes )
Default server side software also will not support such long live connections by default.
More than that xmlHttpRequest object doesn’t give any signals about data sending - so it is quite complicated to implement real constant link with server.

The only simple solution - is use setInterval and grid.load , it may have a small memory leak in IE, because it doesn’t free used XML objects until page reloading.
Alternatively you can check any of standalone “Comet” solution, which can be used as a separate transport system.
Yes, it is complecated.
Thank you for your advises.
