What do you mean by selected (I assume you mean a radio button or checkbox, not a pushbutton?)? And which button? Why don't you just press the button you want selected rather than a different button?

@Adam: Most likely this is a software for an election machine. ;-)

You can set the 'Value' of another GUI element in the callback of the pressed button. This does not trigger the callback of the changed element.

Please post the code of the callback, such that we can suggest matching code more easily.

'SelectedObject' is the property you want, but you need to set it to the object handle, not the tag. Or you can do some stuff with string comparisons and set the 'Value' I guess to 0 or 1 accordingly I guess (or 1 or 2, I've forgotten if radiobuttons index from 0 or 1)

Hi, i found an answer, maybe it will interest the readers. there is a topic in handles.uipanel which is called children, that give the addresses of the buttons inside the panel. what i did was: Currents_pointer = get(handles.pnlView,'Children'); set(handles.pnlView,'SelectedObject',Currents_pointer(2)); i took the addresses from the panel and then set the SelectedObject to get this address and it worked.
