I can validate textbox field by RegularExpressionValidator with regex "^([0-9]{3,3})$". For the required field validation I put requiredfieldvalidator. Thus, I have two validation controls.
Can I combine them into a sigle RegularExpressionValidator? Then what does regex look like? How can I validate empty fields with RegularExpressionValidator?
I'm trying to write a regular expression that allows positive & negative floating point numbers, but doesn't allow empty strings and characters.I have managed to create this
[Code]....
but it allows empty strings and I can't figure out how to add [+-].
My program is a web app which asks the user to input a temperature.
I need to find a regex that tests that an input string contains exactly 10 numeric characters, while still allowing other characters in the string.
I'll be stripping all of the non-numeric characters in post processing, but I need the regex for client-side validation.
For example, these should all match:
1234567890
12-456879x54
321225 -1234AAAA
xx1234567890
But these should not:
123456789 (not enough digits)
12345678901 (too many digits)
I need a validation regex for decimal. It should allow upto 5 digits after decimal.
Allow:
1
1.0
12.0
12.01
123.01
1,123.01
1,123.013
21,123.01234
3,21,123.01234
How Can I do regex for this?
Here's one of the validators:
<asp:RequiredFieldValidator runat="server" ID="rfvCardNumber" ControlToValidate="txtCardNumber" Display="Dynamic" ErrorMessage="Credit card account number is required">*</asp:RequiredFieldValidator>
Here is the JavaScript/JQuery that I am using to disable this control:
ValidatorEnable($("#<%=rfvCardNumber.ClientID %>")[0],false);
This code does indeed disable the client side validation, but unfortunately it does not disable server side validation. I have a way to check to see if I need to validate them or not on the server but it's a bit complex and requires duplicating some code that is used later on to calculate the total due. I use that check and disable the validators in Page_Load and sure enough the validation does not occur. to get these validators disabled on the client & server from the client side?
Is there a WYSIWYG editor that is able to format code?
So when anyone inserts code into the wysiwyg editor box, it would properly format it?
I'm validating input in a asp.net page but the problem is it validates e-mails like hasangürsoy@şşıı.com
My code is:
if (Regex.IsMatch(email, @"w+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*"))
{ valid }
else { invalid }
EDIT: I've written a question before especially to validate e-mail addresses including Turkish characters but now I don't want users to be able to input mails with Turkish characters because users mostly type Turkish characters by mistake and I cannot send mails to these addresses.
Basically, i'm trying to develop a Facebook canvas iframe app in C# ASP.NET that a business can install on a fan page and users can access via a tab.
Main Requirements:
1. Business clicks install which takes them to apps.facebook.com/myapp
2. I needs to check if I have record in database for that Facebook Profile
3. N: Display page where business enters a unique code. Save Profile Id and Code
4. Y: Display data from database related to that business.
The Issue:
I've created app in Facebook and created an ASP.NET website with a single page. The app is running on my dev machine under IIS. When I visit the app on Facebook, it hits my page. I retrieve and validate the signed_request with my API key. However, the decoded payload contains only the SHA256 parameter and no user, oauth, or profile data.
Is there something else I need to do or is my approach completely incorrect?
I'm having a little trouble with using regex in linq. I want to be able to perform a search on values in my database. The goal is to insert a value into the regex and then use that to search a column in a table in my database for that term. I want it to work so that it gets all exact matches and also returns matches in which the search term is a substring of the term in the column.

I like to convert 1234,222 to:
1.234,22
But what happends below is he converts it to 1.234, so verything after the , is gone. How can i change this function so it works correctly?
Also if the number is 1.234,248 the result should be 1.234,25 , so just 2 numbers after the ,
public static string AddDigits(string source, int digitaldigits)
{
System.Globalization.NumberFormatInfo format = new System.Globalization.NumberFormatInfo();
format.NumberGroupSeparator = ".";
format.NumberDecimalDigits = digitaldigits;
decimal i = decimal.Parse("1234,222");//decimal.Parse(source);
//int i = int.Parse(original);
string str = i.ToString("N0", format);
return str;

I have a sql database that on some field will have a empty string/field. I am using a Datalist to display my results. How do I not make the labels that are empty not display? Currently if the field is empty it will leave a space there which my goal is if the field is empty do not leave a white space instead move the other colunms up.
View 2 RepliesI have a TextBox in a FormView that I want to make sure that the user enters exactly 9 digits. The FormView is inside an Update Panel so I want to be able to validate without a Postback. I cannot figure out which validation control can do that and how. I already have a FilteredTextBoxExtender that forces all digits.
