Web Forms :: RegularExpressionValidator Works In IE8 But Not In IE6?
Nov 4, 2010
I have a ValidationExpression that works fine in IE8 and Firefox but client uses IE6 and it doesn't seem to work for them. The issue concerns special characters in a password text box, the clients wants to be able to INCLUDE special characters but IE6 doesn't seem to pick them.
Basically we want to be able to include any letter (upper and lower case) , any number and any special character. This is what I've got so far...
I found the answer to this, but it's a bit of a gotcha so I wanted to share it here.
I have a regular expression that validates passwords. They should be 7 to 60 characters with at least one numeric and one alpha character. Pretty standard. I used positive lookaheads (the (?= operator) to implement it:
(?=^.{7,60}$)(?=.*[0-9].*)(?=.*[a-zA-Z].*)
I checked this expression in my unit tests using Regex.IsMatch(), and it worked fine. However, when I use it in a RegularExpressionValidator, it always fails.
I have a text field where user can enter either an URL or an Email address. How can I use a RegularExpressionValidator to validate that user have entered an URL or an Email address
I have a query on RegularExpressionValidator. Although this question already asked in various time, I just want to confirm that if I want to validate "only alphanumeric or(and) double quote, single quote, exclamation, semicolon, colon, ampersand, dot, comma, hyphen, question mark, front slash, parentheses, space of 5-40 character length" then will the regular expression be this :
Wondering if you could give me a nudge in the right direction. I'm working on an app where I need to validate a field for a correct URL. However, this is an optional field and may be left blankI was just wondering, how can I bypass the validator if the field is null.
Does the RegularExpressionValidator always need a RequiredFieldValidator?I see that when there is no input the RegularExpressionValidator is not working. Correct?
so what did i do wrong with the regex that its now allowing other document types to be uploaded. I need to make sure that ONLY pdf are allowed. What can i change to the validator and if anything add to the code behind to correct this?
My implementation is simple. I have a public static variable in a class called EmailHelper containing my regular expression as follows:
[Code]....
I then have the following web controls on my page:
[Code]....
The problem is that doesn't matter what regular expression I define as the value of my static public variable bound to the <asp:RegularExpressionValidator />, I always get an error (i.e. it aways says "invalid email")...
gularExpressionValidator on my textbox that I am already using, but I need it tweaked. Here is the one I'm using: ^(([0-9]|[1][0-9]|2[0-3])(.)(25|50|75|00))|(24.00)|([0-9]|[1][0-9]|[2][0-4])$It is for the input of hours worked in a day. The minimum is 0.00 and the max is 24.00. The hours are rounded off to the quarter hour, so it allows for .25, .50, .75, and .00.
I am currently working on a web form where you need to make your own account. One of the required fields is where you need to fill in your postal code. I work with an RegularExpressionValidator. This exists out of 4 numbers. The first number may not be a zero. I know that I need the ValidationExpression (propertie of RegularExpressionValidator) but I don't know what to fill in.

I have tried everything and can't seem to wrap my head around it...I am trying to use the RegularExpressionValidator to validate that a asp:textbox has an '' in the value that the user types in, and it can't be the first or last character.
I have a small form with 3 TextBoxes. One textbox I check for numeric values using RegularExpressionValidator / ValidationExpression. Bellow are two buttons: Cancel / OK.
Is there any way to allow the user to continue with "Cancel" even though RegularExpressionValidator finds an error in the textbox?
note: now, if there is an error, whatever user clicks (cancel or OK), nothing happens until the user either corrects the error or deletes the text from textbox completely...
I have an asp:regularexpressionvalidator with the following expression to validate a file upload.
