Hide Validator Message On Text Changed Event

[John]

Hi there,

I have a textbox, button and a RegularExpressionValidator control on a page
to check for an email address. This works fine.....ie I get a message
appearing if the textbox is not valid, but how can I clear the message when
the user changes the textbox?

I've tried : "Me.RegularExpressionValidator1.Visible = False" within a
TextChanged event, but it doesn't seem to be working.

Any clues?

Thanks

John
