A Linq way:

foreach (Control c in parentForm.Controls.Where(x=>x is TextBox))
>            {
>                ((TextBox)c).CharacterCasing = CharacterCasing.Upper;
>            }

Thank you, Viv.
I couldn't think of this syntax.

((TextBox)c).CharacterCasing = CharacterCasing.Upper;

The one I used worked but I prefer this one and I substituted it.
