View 2 RepliesWeb Forms :: Regular Expression Validator For Both English And Chinese
May 7, 2015Earlier 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 1 Replies.net - Regular Expression Multiline Validator?
Feb 23, 2010I 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.

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.

View 1 RepliesHow To Validate The Length Of A Textarea Using A Regular Expression Validator
May 19, 2010I'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.

View 1 RepliesWeb Forms :: Regular Expression For Empty TextBox
Nov 20, 2010I am using regex for server side validations.
I am facing a problem with regex. I want to check for sepecial characters like ><*&()%$@!~+...
I need to filter these special charecters...but the problem is in my 10 textboxes there only 3 are required...
I can submit the form without entering anything...but my regex is not allowing me to submit the form without giving a space from keyboard...
I just want to check for special charecters and empty textbox without giving a spacebar...
I just check these sites(http://regexlib.com/ and http://www.regular-expressions.info/) and read some documentation on regex...its kind of confusing....
Here is my regex for Middlename: ^[a-zA-Z''-'s]|[ ]{1,40}$ its worked but its not correct....then I changed it to ^[a-zA-Z''-'sd*]{1,40}$ this also not taking emptytextbox without giving a space...
My Goal:
In most of the textboxes I need to allow only numbers and - # _ in some textboxes....
For Address: need to allow alphabets and numbers and #-_' "
City: numbers and alphabets no special chars...
Main problem is I can write regex for most of these stuff but need to all textboxes without entering anything (empty textboxes).My work got stoped due to this.
