RegularExpressionValidator and form submission
I have a form that has some fields that I want to validate using regularexpressionvalidator and requiredfieldvalidator. I dont want the form to submit if any of the validations fail. However I am having trouble with the RegularExpressionValidator if I put any values in there the form submits, even if a) it doent fit into the validation i put in
and b) the other required fields are not even filled in.
Can someone help me with this?
here is my code:
Code:
<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="JobInfo.aspx.vb" Inherits="AjaxUploader.JobInfo1" %>

Re: RegularExpressionValidator and form submission
Is this right?
^[0-9]*${10}
It means "I want a number, 0 or more times, 10 times". So that should match up with a blank string, shouldn't it?
Try
[0-9]{10}

Re: RegularExpressionValidator and form submission
Do you, anywhere in markup or code, change the causesvalidation property of the button? The button's CausesValidation property should be set to true.

Re: RegularExpressionValidator and form submission
The "causeValidation" property is True.
I tried changing the regular expression as you described and I am still running into the same strange problem. Again what happens is, if the fields are empty then it wont submit, as soon as I put any text into the box of the "RegularExpressionValidator" then the form submits even though the other fields are still empty.
I already pasted my code in the original post.
Any help with this would be appreciated.
Thanks.

Re: RegularExpressionValidator and form submission
Strange problem - maybe strange markup.
You have javascript events firing onChange ="FillHidPhone()" on many text boxes that change the textbox your refering to "hidPhone" like document.forms[0].hidPhone....... and there is another javascript function refering to hidPhone at the bottom of the page and your wanting to use required & regex validators on it aswell.....
What are you trying to achieve ?

Re: RegularExpressionValidator and form submission
I have 3 text boxes for the phone number. I want to do a validation check on the entire phone number (all three textboxes) someone gave me the idea of putting all the textboxes together into one hidden texbox and then validating the hidden textbox. do you think the javascript could be what is causing the problem?

Re: RegularExpressionValidator and form submission
Now I see what your trying to achieve. Without testing it I'd say the javascript will be the problem, as well your regex expression is not correct.
You may be able to find a combination of JS and validation controls that works. Personally because what your doing is "outside the box" or specalized I'd just use javascript.
The best/simplest solution could be to use 1 textbox (not 3) a required & regex validator.

Re: RegularExpressionValidator and form submission
Your form is starting to make sense now, but is unnecessarily complicated. You can go for 1 textbox with a phone regex, or if you stick to three textboxes, then validate them together using a custom validator. A custom validator control lets you specify a javascript method that you can call when validating client side, as well as a server side validating method.
