New-ish to regular expressions and this is driving me nuts.  I've got a RegularExpressionValidator and I need the input to be a number at least 13 characters long.  I'm sure this is a snap but I cannot get it right.

TIA,

this should get you started:

"\d{13}"

see below usage


hth
<asp:TextBox ID="txtTest" runat="server"></asp:TextBox>
<asp:RegularExpressionValidator ID="rev01" runat="server" ControlToValidate="txtTest" Text="Error" ValidationExpression="\d{13}">

Will this do?
^[1-9]\d{12}$

@fanopoe:
\d{13} will take "0000000000000", or "0100000000000", etc,  as valid numbers,

This did not work:

<asp:RegularExpressionValidator ID="rfvBillingAccountNumber"
                                    ControlToValidate="txtBillingAccountNumber"
                                    ValidationExpression="^[1-9]\d{12}$"
                                    ErrorMessage="A billing account number must be 13 digits, numeric, and is required to add a customer."
                                    Display="dynamic"
                                    runat="server"/>

Thank you for the suggestions, but will these also validate against no input either?

After reviewed the original question, I changed my expression to this:
^[1-9]\d{12,}$  ''<== Added a comma to meet the requirement: at least 13 characters long
Note: [1-9] will ensure that numbers with leading 0 are not allowed.

You will need a RequiredFieldValidator again no input value.

Your error message says "A billing account number must be 13 digits, numeric, and is required to add a customer.". It does not match your original requirements: at least 13...
My first solution matches numbers with exactly 13 digits, and the modified solution matches numbers with at least 13 digits.
