I have a page with required field and regular expression validators. I noticed recently that some of the regular expression validators (the regex validators on the Date fields) are not firing. What should I be looking at to troubleshoot this?

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+)*
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>
here is waht i am trying to achieve.
first character is in caps and the rest of the name is in small for Firstname Space
first character is in caps and the rest of the name is in small for lastname
ex: Ajay Kumar Bakshi
expression: ^[A-Z]{1}[a-z]*[s]{1}[A-Z]{1}[a-z]*$
what is the regular expression validator for letters only?. I have tried this"[a-zA-Z]" and "[a-z][A-Z]" with no luck..
View 4 RepliesWhen I added Regular Expression validator on FileUpload Control, Page.IsValid returns false & Data is not Saved. I had used Regular Expression Validator like this:
asp:RegularExpressionValidator
ID="REVFileType"
runat="server"
ErrorMessage="*Invalid File(.bmp)"
ControlToValidate="FileUpload1"
Font-Bold="True"
SetFocusOnError="True"
ValidationExpression="^(([a-zA-Z]:)|(\{2}w+)$?)(\(w[w].*))(.jpg|.JPG|.gif)$"></asp:RegularExpressionValidator>.
I had used it to check if uploaded file is of extension .jpg|.JPG|.gif

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.
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?

View 1 RepliesI need Regular expression validator for validating date format dd/MM/yyyy
View 1 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.

I'm having a hard time trying to create a right regular expression for the RegularExpressionValidator control that allows password to be checked for the following:- Is greater than seven characters.- Contains at least one digit.- Contains at least one special (non-alphanumeric) character.Cant seem to find any results out there too.
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.

View 1 RepliesI'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 RepliesI 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}$"></asp:RegularExpressionValidator>
I want to maintain the consistency of my database, I want the first letter and every letter after a space to be capitalized before the record can be entered into the database. Currently my validator expression (^[A-Z]+[a-zA-Z]*[0-9]*[^f
v]*$) can achieve only the first capital letter and it can't check on the letter after every space, so what is the expression to achieve that?
i have to check if an input string is valid based on the given regular expression.. this is the regular expression.
(a(bb+aaa+((ab)*bb+(aba)*aa)(a+b)*) + (b(aa+bbb+((ba)*aa+(bab)*bb)(a+b)*)
+ is an OR
* is a LOOP, it is optional, it may be done as many as a user wants.
