ItemIndex:=-1 doesn't work

Original Reporter info from Mantis: septem
  • Reporter name:

Description:

«RadioGroup.ItemIndex:=-1» does not work: the first item is always selected.
When I create a RadioGroup, using the components panel, the first item is selected. I can't set «ItemIndex: -1» in the Object Inspector. But I can remove this selection, using «radiogroup.itemindex:=-1;».
However it works only if a radiogroup was created with the components palette. If I create this component dynamically (r:=tradiogroup.create(form1)...), «r.itemindex:=-1;» doesn't work at all.

Additional information:

See an example in the attachment.
