validation

[Guest]

I have a AutoCompleteExtender and I bound it to a textbox. It is the list of
all email address and last name and first name

(e-mail address removed) (nancy Multani)

(e-mail address removed) (babay Gill)

I want to validate this text box. I want to create new validation control
the text box I type only that item which appear in drop down list or select
valid item or type whole string.

How can I do that.

use a custom validator, on submit check the value in the text box and
set the validator to false if it isn't in the required list.
