Regular Expression Validator error for masked SSN number

Posted By:      Posted Date: October 10, 2010    Points: 0   Category :ASP.Net

Hi all,

I need a small help.
Below given is the ASP.NET Regular Expression Validator that i am using to validate the SSN number being used in my project.

<asp:textbox id="txtSSN" runat="server"  size="14" onBlur="javascript:return mask(this.value,this,'3,6','-','Pri');" maxlength="9" AutoCompleteType="Disabled"></asp:textbox>

<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ErrorMessage="<span style='display:none'></span><img src='../images/arrow.gif' alt='Enter a valid 9 digit SSN number'>" ControlToValidate="txtSSN" ValidationExpression="^[0-9X]{3}[\- ]?[0-9X]{2}[\- ]?[0-9]{4}$"></asp:RegularExpressionValidator>

In this project the SSN number is masked before being displayed to the user.
Below given is the format for the display of the SSN number in the front end code

SSN NUMBER in the code behind            :     333-44-2222
SSN NUMBER displayed in textbox as    :     XXX-XX-2222

Validation Summary with regular Expression validator


I have a page that im using Validation Summary on. I have 5 out of 8 fields that im validating. All 5 have required validators and 1 of the 5 also has regularexpressionvalidator with it.

When the page load and i click the submit, all the fields show my red * next to them and the individual messages down in the summary. Thats find, but im having issues with checking the field with the regex validation when you submit the form again. At the moment, i had added a if condition on the button event and it is preventing the form from submitting and the field is showing the red * next to it, but my message from the regex validator does not display in the summary. Actually the summary doesnt even show up. The regex validator works when you tab out of the field by placing the red *, but the actual error message doesnt display in the summary, so you wouldnt know why there is an issue.


I have the following as a test, def isnt correct, but was trying to show the summary with the value from my regex validator:

        protected void btnInfo_Click(object sender, EventArgs e)
            if (!Page.IsValid)
                vsSumm.ShowSummary = true;

Regular Expression Validator



i have been using the Validators on my forms to validate the information placed into an intranet Email form.

with the form being internal i was hoping to change the "RegularExpressionVaildator" to see if its a vaild email and dis allow it.

Reason being is once the form is completed the last part of the email is completed within the code e.g. @hotmail.com is added.

Below is the Vaildator code i have am just unsure on how to change it.


<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" 
                    ErrorMessage="Do not enter @hotmail.com" 



Regular expression to split number


I am splitting the phone number entered into two parts using regular expressions below

This works fine if entered value is 1234567890 or 123-456-7890

and fails if value entered is 123 456 7890 (with spaces) or 123.456.7890

how to modify above expressions to trim (spaces and .)?

Syntax error (missing operator) in query expression

Good Day Gurus!

I have a Excel user application which has a user form (named 'Registo') that displays criteria and an image that has been entered in it's corresponding spreadsheet. This works the way it should.  There's also the ability to search the spreadsheet via a form (by clicking 'Pesquisar' button) this opens a search form. However, I having a bit of a problem with it. When I try to search for something it basically doesn't do anything at all. It just sits there. So I tried to debug it and I think I'm having a problem with either the JET db engine or somethign with teh query or maybe I don't have the correct reference.

I 'borrowed' this Excel application from another forum because it's exactly what I'm looking for! However, I suck at vb.

So I was hoping somebody could take a look at the code and see if I'm missing something?  I'm kinda' desparate to get this working because I'm been trying to figure it out for days and I'm running out of time.  Cry

Need a regular expression


I have a required field validator for a texbox, but I just found out that the texbox can have a space in it (for a delimiter, let's say).

I checked the .net and regexlib.com, but couldn't find what I was looking for.

I simply need a regular expression that basically excepts any character string including spaces in it or even a space by itself

Can someone help me out?

Matching set of characters via regular expression

I need to be able to match sets of quote and space characters in a string and replace these accordingly. I currently have this done in 2 lines of code, but would like to use regular expression so that I can use only 1 line of code. See below: var Qt = unescape("%22"); //quote char var Sp = unescape("%20"); //space var Cr = unescape("%0d"); //carriage return var Lf = unescape("%0a"); //line feed var CrLf = Cr + Lf;  //carriage return & line feed stringOut = stringIn.replace(Qt+Qt+Sp+Qt,Qt+Qt+CrLf+Qt); stringOut = stringOut.replace(Qt+Qt+Sp+Qt+Qt,Qt+Qt+CrLf+Qt+Qt);   I want to replace space in string like in pattern below with carriage return line feed: (in hex) 22 22 20 22 or 22 22 20 22 22. This needs to return 22 22 0D 0A 22 or 22 22 0D 0A 22 22   Line in green above will only match and replace 22 22 20 22 , but I want have regular expression into 1 line of code which  will match and replace either 22 22 20 22 or 22 22 20 22 22
