RequiredFieldValidator

[aspamit]

I have a Dropdownlist which I kept enabled or disabled depending on case.I want to check that if that dropdownlist is enabled then something must be selected and if it is not enabled then it may proceed.
I use RequiredField Validator but it doesn't work as I want.It checks even if that dropdown is disabled.
How can I resolve this?
Any help is appreciated.
