asp.net - What is the intended use case of a RadAjaxManager w/ Ajax requests versus an UpdatePanel/RadAjaxPanel -

i'm confused @ benefits of using radajaxmanager ajax requests versus using , updatepanel/radajaxpanel. have both in solution , creating havoc. design methodologies typically deemed best (a bit subjective realize)

should perform data operations using ajax , gui updates using updatepanels/radajaxpanels?

currently updating controls via ajax manager triggered ajax request , control postback entirely. if decide via ajax, have make sure nothing ever posts back?

check official statement. think mixing ms ajax telerik not idea.
