I am using regular expression validator for Numbers, Comma and Decimal.. The expression is given below.
mNumValidator.ValidationExpression = "^(d|,)*.?d*$"
Now I would like to have 5 digits behind decimal.
I need to validate the text box at server side by using regular exp which should accept 1 or 2 or 3 or 4 or 5 digits numbers .Need to restrict decimal part.
Ex: 1 or 23 or 455 or 5643 or 45667 --Should accept.
1.3, .2, 33.3 , 444.55 ,5555.99 -- should not accept.

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.

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

When 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

ControlToValidate="FileUpload1"
Font-Bold="True"
SetFocusOnError="True"
ValidationExpression="^(([a-zA-Z]:)|(\{2}w+)$?)(\(w[w].*))(.jpg|.JPG|.gif)$"></asp:RegularExpressionValidator>.

View 2 RepliesEarlier my text box was running on this Validation Expression="^[a-zA-Z'.s-]{1,80}$", to allow only alphabets,Ā Ā ' . s . Now my text box should be capable of taking Chinese characters as well, so I wasĀ learntĀ onlineĀ to use this p{L} for unicodeĀ instead of Ā a-zA-Z, and set EnableClientScript="false".
asp:RegularExpressionValidator ID="regexpName" runat="server" CssClass="failureNotification" ErrorMessage="No Special Characters allowed"
ControlToValidate="txtName" ValidationExpression="^[p{L}'.s-]{1,80}$" Display="Dynamic" meta:resourcekey="regexpNameResource1" EnableClientScript="false"
I have done both, but it doesn't work. My input values were like
1. John123 2. ę±čÆ%^&
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 4 RepliesI 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"

ErrorMessage=" * "

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