Posted 10 September 2017, 11:28 am ESTI have a C1MaskedInput control for Phone number (Non-Mandatory). I have a regular expression validator to validate the phone number. When I skip the phone number the regular expression validator is not supposed to fire an error (like it used to behave for other textbox controls). Here is my code:
I see that the help shows how to do a "Alert box" on error.
But I need to display it automatically like it does for other asp:RegularExpressionValidator controls.
Is there a way to do it? (I know that Ajax tool kit has maskedInputextender and maskedInputValidator - Is there anything similar with C1?)
