.net - Regular Expression Multiline Validator?

Feb 23, 2010

I believe it is a simple question. :)

In my ASP.NET Web Form I have a multiline TextBox which should be validated with RegularExpression Validator. Text box should contain one ore more strings "a" (just 'a' char, nothing else).

So far I got these regular expressions for my RegularExpressionValidator object:

(?m:(^a$)+)
(?m:A(^a$)+)
(?m:^a$)

Neither works. :) Guess there is something fundamental I'm not getting yet.

Web Forms :: Regular Expression Validator / Add Wording To Current Expression:  W+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*?

Feb 16, 2010

I'm trying to use the validator to work on a email form to ensure that they enter a valid from email address. That part works. I also want to add to the expression the text that I pre-populate in the txtbox ("Enter your email address") so on postback, after sending the message, I can clear the fields and repopulate that box.

How do I add that wording to the current expression: w+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*

How To Validate The Length Of A Textarea Using A Regular Expression Validator

May 19, 2010

I'm looking to validate the length of a textarea using a regular expression validator. It should allow all characters and crlfs. I'm also concerned about crlfs counting as 1 or 2 characters, I'm concerned it may be different across browsers but I'm hoping ASP.NET regulates it. Also, I'm saving to a mix of varchar and nvarchar fields in MSSQL, do I need to be concerned about the way crlfs are saved there? I'm in a hurry to do this right, so I'll be researching all this on my own but I'm just hoping someone out there might have experience handling such concerns.

Regular Expression Validator Does Not Validate Empty Textbox?

Jun 30, 2010

I would like to validate the textbox for specific text and it must not be blank. But the regular expression validator is not validating if the text box is BLANK. However, it validates if I type something in the text box.

How can I make regular expression to trigger even if the text box is empty?

Should I use Required Validator + Regex Validator at the same time?

<asp:TextBox ID="txtcard" runat="server" MaxLength="16"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator2" runat="server"
ControlToValidate="txtcard" ErrorMessage="Please type credit card no"
ValidationExpression="^d{16}$"></asp:RegularExpressionValidator>

Web Forms :: Regular Expression Validator For Both English And Chinese

May 7, 2015

Earlier my text box was running on this Validation Expression="^[a-zA-Z'.s-]{1,80}$", to allow only alphabets,  ' . s . Now my text box should be capable of taking Chinese characters as well, so I was learnt online to use this p{L} for unicode instead of  a-zA-Z, and set EnableClientScript="false".

asp:RegularExpressionValidator ID="regexpName" runat="server" CssClass="failureNotification" ErrorMessage="No Special Characters allowed"
ControlToValidate="txtName" ValidationExpression="^[p{L}'.s-]{1,80}$" Display="Dynamic" meta:resourcekey="regexpNameResource1" EnableClientScript="false"

I have done both, but it doesn't work. My input values were like

1. John123 2. 汉语%^&

Both of these were accepted without any errors. But I expect only alphabets in english and chinese and ' . s - to be accepted as Name input.

Web Forms :: Right Email Bounces By Default Regular Expression Validator?

Jan 12, 2011

I have this email, which I know is valid:

MyName@MyDomain.info

I am validating an input field with the default asp net email validator expression and it returns the email address as INVALID.

Here is my code:

<asp:RegularExpressionValidator
ID="RegularExpressionValidator1"
runat="server"
ValidationExpression="w+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*"
ControlToValidate="Email"
runat="server"
ErrorMessage=" * "
/>

Is there a better regular expression pattern to validate an email address?

Web Forms :: Regular Expression Validator Does Not Work With Aspx Generated Register Form

Jan 2, 2011

I'm trying to add a regular expression validator to verify the email text box that is within a Create User Wizard. The form that I'm working with is called Register.aspx, and is the form that is auto generated when you start a new web application found under the Account folder.

For some reason the code below is not firing off when I enter an email address that is incorrectly formatted. I have a feeling it's because I manually added the code within the form but that's just my guess.
