i have a login page.
i am using requiredfieldvalidtaor and reularexpression validator on the same textbox.

The problem is that ,only requiredfield validator is getting fired. and not the regular expression.

For Example:

email: left empty.hence requiredfield will fire

email: abc@dfbmw regularexpression will not fire.

Both are working fine if used seperatly but when used together,the problem arises.
