Thanks, Naomi

I woke up from my trance and this did it

 foreach (Control c in parentForm.Controls)
            {
                if (c is TextBox)
                {
                    TextBox tb = c as TextBox;
                    tb.CharacterCasing = CharacterCasing.Upper;
                }
            }
