I have a radiogroup box which is empty at design time but becomes populated at run time. When I pupulate it the item index is always -1 which means that no buttons are checked.

I can't find a way to set the dirst radio button as checked in code. I can set the item index, but this does nothing for the checked status of the button.

Any ideas

Hi mike_tipping,

to set radio button checked:
   RadioGroup1.ItemIndex := nn;
to clear checked button you should check another button

to clear all buttons set
  RadioGroup1.ItemIndex = -1;

Hi,

You might find that you are better off using a GroupBox and indiviual TRadioButtons in the GroupBox. RadioButtons in a GroupBox are mutually exclusive just as they are in a TRadioGroup, but you have the advantage of setting the Checked value of a specific radio button and having the OnClick event for the RadioButtons.
