I'm wanting to remove all the special characters (leaving only numbers) in a phone textbox. Here is my current code:
Regex.Replace("(123)456-7890", "[\(\)\-\.+]", "");
I need to construct a regular expression for the password textbox which shouldn't accept special characters($,@,!,etc).Even whitespaces,tabs. I tried the below this accepts special characters.
<asp:RegularExpressionValidator ID="RegEx" runat="server" ControlToValidate="Password"
ErrorMessage="Password must be atleast 8 characters and include a number,alphabets upper case and lower case.
"ToolTip="Password format is not correct"
ValidationExpression="^(?=.{8})(?=.*d)(?=.*[a-z])(?=.*[A-Z]).*$">
</asp:RegularExpressionValidator>

I'm using RegularExpressionValidator controls to impose password rules when creating new passwords. I want to avoid repeatitons such as 'aaaa' or sequences such as '12345' in the password.
How do I write the validationexpression to a RegularExpressionValidator to impose this rule? I do not want to do thing using C#, just with a regular expression that could be put within the validator control like below:
<asp:RegularExpressionValidator
ID="RegularExpressionValidator3"
runat="server"
ErrorMessage="Password
should contain Minimum 8 Characters"
ControlToValidate="txtPwd"
ValidationExpression="w{8,30}"><asp:RegularExpressionValidator>
There may be an easier way, and if there is I'm all for it. However - my ASP.NET page has a TON of controls on it, and I've given them all ID's that start with underscore. I copied all the markup into Notepad++ and I'm trying to find a regular expression that will find everything but the controls and replace it with whitespace. that way I'll have a text file that has all my control names which I'll probably throw into Excel and do some string manipulation to add ".Text = " etc.
