radio button - ASP.NET Radiobutton list set to autopostback but not posting back if selected item changes -

-

i have radiobuttonlist have set autopostback, when user clicks button, there no postback.

any suggestions?

i assume "when user clicks button" mean when user clicks 1 of radio button options. without seeing code, 2 common scenarios be:

  1. a script error occurring preventing postback (script errors can detected in ie or via firefox , firebug extension 2 diagnostic options)
  2. updatepanels involved, , attempting use autopostback refresh updatepanel

if latter scenario , using updatepanels, try putting radiobuttonlist inside own updatepanel, autopostback set true on radiobuttonlist , updatemode on updatepanel set "always" (the default value).
