Validation Expression For UserName Using C#?
Sep 27, 2010
I am developing a login form with User Name and Password. I want the user to create the username in a specified format. So i am using RegularExpressionValidator for the username. What is the Validation Expression for this format.
The format is:
xyz\t4z4567 (characters are not case sensitive)
Rules:
The username will be created in the above format. first 5 characters(xyz) are same for every username with the slashes. Only "t4z4567" will be changed for every user.

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 am trying to verify if a username is taken or available by using jquery to send a request to an asp.net page. The ASP.net page is clearly getting the information as I am having it make an entry into a log database. My SQL server database indeed shows the username being passed to it and is returning a value however for some reason the client side html/javascript doesn't RESPOND to it. I am not sure if it is on the end of my html/javascript or perhaps my asp.net page is not returning the json information correctly? This is my first attempt at json The checking availability box shows up on the html page but it NEVER changes even when the sql server shows that it ran the stored procedure

I have a regular expression validation set on text box. I have a grid on the same page with edit and delete buttons. In some cases I don't want the regular expression to fire. For example, I have a scenario where the text box will be disabled but I can still enter data in to the grid and modify it, but the regular expression fires when I modify the grid and the changes in the grid are not processed.how can I stop the validation when I am working on grid. I can see a property causes validation for button to stop validation but don't know how can I stop for the grid.

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.
