Asp.net regex validator does not work

Question

My textbox should contain 8 digits. If not i want to pop up an alert box. But the regualr expression validator does not trigger. Why?

<asp:LinkButton ID="LinkPayment" CssClass="btn mainBtn" runat="server" onclick="LinkPayment_Click" OnClientClick="_gaq.push(['_trackPageview', '/virtualgoal/smspayment']);">Betal ></asp:LinkButton>  

<asp:RequiredFieldValidator ID="RequiredCustomersPhone" Display="None" ValidationGroup="ValGroupCustomersPhone" ControlToValidate="CustomersPhone" runat="server" ErrorMessage="Du må fylle inn ditt mobilnummer!"></asp:RequiredFieldValidator>   

<asp:RegularExpressionValidator ID="RegExValCustomersPhone" ValidationGroup="ValGroupCustomersPhone" runat="server" ControlToValidate="CustomersPhone" Display="None" ErrorMessage="Telefonnummer må bestå av 8 siffer!" ValidationExpression="[0-9]{8}"></asp:RegularExpressionValidator>

<asp:ValidationSummary ID="ValidationSummary" ShowSummary="False" ValidationGroup="ValGroupCustomersPhone" ShowMessageBox="True" runat="server" />

FYI, the first line of your markup is invalid (extra chevron before the closing linkbutton tag). — Tim M.

Add the following code:

ValidationGroup="ValGroupCustomersPhone"

to your linkbutton

Are you trying to validate an empty field? You may need a required field validatior as well. It's a shame there is no 'ValidateEmptyText' field on Regex validators.

Still fair suggestion though, it won't fire if its blank.

Ok, i see what you mean, and I was testing it with content. To few/many digits and chars.
