I am using Regular Expression validator for a text box. The below is working fine.It is not performing validation when I enter values like 0000..001.How can I modify validation expression? But it would allow values like 100,...5000 i.e zeros after a number.
<asp:RegularExpressionValidator ID="reg2" runat="server" ControlToValidate="rng2"
ValidationExpression="^[0-9]+" ErrorMessage="*Please Enter a Valid Number for Second Range."
ForeColor="Red" Font-Bold="True"></asp:RegularExpressionValidator>
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?

I need Regular expression validator for validating date format dd/MM/yyyy
View 1 Repliesi have an requirment where an user can enter multiple email address.
The validation should ensure that he should enter address in the format "something@abc.com".
my existing validation ensures that some text is entered before "@" symbol and "abc.com" is the domain.
@"w+([-+.']w+)*@abc.com$";
I would need my regex to check for the delimiter ";" between two mail id's .
valid: a@abc.com |
a@abc.com;b@abc.com|
invalid: a@abc.comm | a@abc.com,b@abc.com | @abc.com |
a@abc.comb@abc.com|

View 2 RepliesEarlier 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è¯%^&
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.

View 5 RepliesI 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.

View 1 Replies 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.
