Problem with RadioGroup.ControlCount in Delphi 2010

Question

I\'d like to set RadioButton properties in runtime in procedure InitRadioGroup(). It fails because RadioGroup.ControlCount is 0, although there are 3 RadioButtons in RadioGroup

Answer 1

I assume that the RadioGroup is not visible when your procedure is called. So the RadioButtons may not be created then.

A call to RadioGroup.HandleNeeded should fix this for you.
