Q: CompareValidator

[Soul]

Hi,

I am trying to use CampareValidator to validate two text fields so that they
cannot be enter with same text. Can I know is there a way to make
CompareValidator become validate character case as well? I understand that
task can be easily done by using CustomValidator, but I have been force to
use CompareValidator. Or is there a way to force TexBox to change case while
user typing? I think CharacterCasing property only available for WinForm but
nor ASP.Net...

Thank you.
