Javascript Form Validation Error Message
Sign up How can I rewrite the ErrorMessage for a CustomValidator control on the client? up vote 6 down vote favorite 1 I have a CustomValidator that is validating a telephone number for several different telephone numbering schemes. The client-side javascript looks like this: validatePhoneNumber(sender, args) { cleanNumber = args.Value.replace(/\D/, ""); country = $("#" + CountryID).get(0).value; switch (country) { case "North America": asp.net custom validator display dynamic args.IsValid = validateNAPhoneNumber(cleanNumber); if (!args.IsValid) sender.errormessage = "* Not a NA Phone #"; break; case "UK": args.IsValid = validateUKPhoneNumber(cleanumber); if (!args.IsValid) sender.errormessage = "* Not a UK Phone #"; break; ... } } The actual validation takes place properly, and the CustomValidator has the correct IsValid property at all times. The sender.errormessage, however, seems to be rewritten just after this function call to it's default value. How can I change the errormessage value, and make it "stick"? asp.net javascript validation client-side ecma262 share|improve this question edited Aug 5 '09 at 2:15 asked Aug 4 '09 at 22:46 Dustman 2,09772638 add a comment| 9 Answers 9 active oldest votes up vote 3 down vote The best way to change the error message of a validator control with image is: sender.innerHTML = "YOUR HTML WITH ANYTHING COME HERE" share|improve this answer edited Jul 25 '15 at 12:05 Falko 6,78572150 answered Jun 13 '12 at 4:47 Satyavir Yadav 312 add a comment| up vote 3 down vote function dateofbirth(source, args) { var dtcDOB = document.getElementById('<%= dtcDOB.ClientID %>'); var dob = new Date(dtcDOB.value); var currDate = new D

Sometimes we use a custom validator control instead of other controls to implement our custom logic to validate user input.We use the ErrorMessage property to display the error message. Assume you get a requirement to display the error message dynamically. Then it will not help to implement it directly (we need to implement it in code behind, not in the aspx page). So we need a way to display the dynamic error message. It can be implemented in one of the following two ways: 1. Using JavaScript 2. Using OnServerValidate property Let's start with how to implement a dynamic error message
Answer: If the client validation method is called CheckEntry, then your code would need to look like this: The error message is updated via the sender.errormessage property. The "ValidatorTrim" method is provided by a method from JavaScript that ASP.Net injects for you into the page whenever you use a validation control. Simple and Easy!
