how to disable parent windows while uploading file like processbox
Hello anujtarun, you can use echo event, look at this: Event_Firing look at te final of link: "Event echoing is useful for implementing a long operation. HTTP is a request-and-response protocol, so the user won't receive any feedback until the request has been served and responsed. Thus, we could send back some busy message to let the user know what has happened, and echo back an event to do the long operation. For more information, please refer to the Long Operations: Use Echo Events section."
