Hi Guys,
I noticed that the error message of my regularexpressionvalidator dissapears when the postback happens.
Ideally I dont want that a postback is possible as long as an error is there. How can I do this?
The regularexpressionvalidator:
<asp:RegularExpressionValidator ID="RegularExpressionValidatorForEmailAdddress"
runat="server" ControlToValidate="Email"
ErrorMessage="bbbbbb."
ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"></asp:RegularExpressionValidator>
the checking on postback (checking user names and if they are already used) - is there a different way to do this?
