validation problem

I'm using asp.net 2005.(C#)

In my web page there are lot of compulsary fields. so I used requiredfield validators.

before submit and fill compusary fields I get a ID from DB by clicking a button. but until I fill all that required filds I cant do that.that is a problem.

second problem is I cant clear page after submiting coz password and confim password fields get cleared afeter submiting.I set password field as required field.

can I avoid these two problems.

can I clear validors also.

plz help .
