query regr.. radiobuttons

[srivalli]

i have 2 radiobuttons in a group box1.

and i have one more group box in which i place 2 radiobuttons.

when i select one of the radiobutton in groupbox1 , the second radiobutton(radiobutton2) in groupbox1 should be made disabled,i mean not the control but the checked portion should be made read only and
one of the radiobutton in groupbox2 should be made readonly.

which event should i take to do some calculations when i select any one of the radiobuttons.

suggest.

The CheckedChanged event is most likely what you're looking for. If you double click the RadioButton, an eventhandler will be created for the RadioButton's CheckedChanged event.
I'm not really following the logic behind making one of the radioButtons disabled/readonly. Are you trying to make the selection of a choice a one time only thing?
