Reset Button clears everything except RadioButton

Posted by Lionel on March 14, 2006

I have a Button set up on my form as a "Reset" button. Its purpose is to clear everything for another run or another calculation.
I am clearing the Edits with   Edit1.Text := '0'
and the labels with   Label1.Caption := '0'
and the ListBox with   ListBox1.Clear

I have not found a way to include a clear statements for the two RadioButtons being used to make a selection.
-----------------------------------------
My Reset Button clears the following:

Edit1.Text:='0';
Label1.Caption:='0';
ListBox1.Clear;
------------------------------------------
I tried "RadioButton1.Clear" but that is not working so when I run another calculation one of the RadioButtons is already checked.
