You could achieve your goal by hooking the OnRequestStart
event of RadAjaxManager
. This event will be fired just before the request is sent. On this event you could find and disable all the controls that you want.
After, the request has been sent and as soon as the response is received you need to re-enable the controls. You could do that by hooking the OnResponseEnd
event. Here you will need to find once again the controls and set them as enables.
Give this approach a try and check whether it is working for you.
