I am using regular expression for checking the subnet masking. I use ajax txtbox with masking value but that is not working, then I switched to a textbox and applying a regular expression for that. unfortunatly that one is also not working.
Solution: I was using masked text box and don't know how to put validation expression. Finally I found a property of masked text box as validation expression, and there I put the RE and change the property validate to true. No need to use validator expression explicitly.
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>
I need some help in regular expression.I am validating the textbox text when updating the records.When i click the update button,the first 5 letters should be equal to CM000 or cm000.How to validate this using regular expression in asp.net. does anyone know validationexpression for this.
I would like to know what the expression for "letters only" is for my asp.net web application. I tried ^[A-Za-z] but it does not work I would also like a regular expression for "numbers only except "-"
I am trying to write a Regular Expression Validator to allow users to input any number (either positive or negative), except 0. I tried the followings but obviously they failed:
^[1-9-]{1,10}$ <= failed when the 2nd to n-th digit is 0
I am using a regex to detect forum tags within posts, such as "[quote]text[/quote]" and then replace them with HTML formatting. I posted a question Forum tags. What is the best way to implement them? about a problem with nested tags.
Right now this matches an opening and closing tag, with match groups for the tag name, the tag content, and an optional value like the value after the equals in this forum tag [url=www.google.com]click me[/url].
What I need is for the expression to match the opening tag OR the closing tag and have a match group containing the tag name (including the '/' for the closing tag). I then want to iterate through them sort of like this:
Dictionary<string, int> tagCollection = new Dictionary<string, int>(); inputString = Regex.Replace(inputString, @"expression I'm asking for here", match => {
[Code]....
So now, each tag is appended with a number and I could use the original regex to perform the tag functions and properly handle nested tags as separate tags.
I got this code from a regular expression library to get the src of the image found in a given input. However I can't get it to work because the double quotes(") in the regular expression is closing the string under the second parameter for the .Match function. I tried changing double quotes(") to " but it doesn't work too.
I have custom control for create user. I use RegularExpressionValidator with expression (?=W{1,}){7,} (lentgth min 7 character and must include not less 1 NotAlphaNumeric character) . I test this expression
function GetText(AInputText) { var VRegExp = new RegExp(/(?=W{1,}){7,}/); var VResult = VRegExp.test(AInputText); return VResult; }
it's work. But RegularExpressionValidator doesn't accept this expression for input - 1234567! or 12345qwer!
I am a new to regular expressions.I need to validate an identification number so that the textbox doesn't accept numbers like 1111111, 2222222, 3333333......9999999 and 1234567, 2345678, 3456789.Could someone please post regular expression for not accepting such format.
