Add Error To Validationsummary From Code Behind
a minute: Sign up Add error message to @Html.ValidationSummary up vote 19 down vote favorite 7 I'm using standard MVC3 Razor views with unobtrusive Javascript validation, using @Html.ValidationSummary to show them at the top of the form. If the standard validations (things like [Required]) pass, I then run some very custom client-side validation that fires when the user hits the Submit mvc add error to validationsummary button. (The validation looks across a number of form elements to make sure that the proper set of them have been checked, etc., so it's not as simple as just creating a new custom validator for a single field). I'd like the possible error(s) I construct there to be shown in the ValidationSummary list, but I can't figure out how to get the error message to appear there. asp.net-mvc-3 unobtrusive-validation share|improve this question edited Aug 22 '12 at 9:08 Eranga 26.3k36478 asked Oct 24 '11 at 21:10 Kras 2432612 In client-side or server-side? –Javad_Amiry Oct 24 '11 at 21:16 add a comment| 2 Answers 2 active oldest votes up vote 32 down vote In client-side: function YourCustomValidator() { // do your validation logic here via JavaScript return true; // or false based on your validation logic } $(document).ready(function () { // take your own form-selector like ("form", this) $("form", this).first().submit(function () { return (YourCustomValidator() && $(this).valid()); }); }); OR In server-side: Think you have a model like this: public class Test { [Required] [StringLength(100)] public string FullName { get;
In general, field specific validation shows up next to a control that it is validating (assuming you put the validators next to it). But what about validation that asp.net add error to validationsummary happens in a Domain Service Class or your Custom BLL for example? These exceptions validationsummary add message programmatically will by default be caught by the application and show as a nasty error to the user, or go to add error message to validation summary using jquery the error page. This is hardly the desired behavior for a validation error. First I like to change the default behavior of bubbling up to the application to be caught to being handled http://stackoverflow.com/questions/7882008/add-error-message-to-html-validationsummary at the button or page level. To do this I put a try-catch in my button action or other applicable event that you can tap into. In the catch, it would be ideal to add a custom error message to the ValidationSummary. How do we do that though? Thankfully, it is quite easy to add an item to the ValidationSummary. The key is that the Page http://justgeeks.blogspot.com/2010/11/adding-item-to-validationsummary.html has a Validators property that all validators are automatically added to when you put them on your .aspx page. The problem is that we don't have a CustomValidator. Thus we need to create a CustomValidator, but what a pain really since we only want to use it when we actually have an exception in our BLL. My solution is to create method to encapsulate the logic to create a new CustomValidator and add it to the Page's Validators collection. So that it can easily be accessed on any page, I have implemented it as an Extension to the Page class. Below is the code to do so. namespace MyExtensions { public static class PageExtensions { public static void AddValidationSummaryItem(this Page page, string errorMessage) { var validator = new CustomValidator(); validator.IsValid = false; validator.ErrorMessage = errorMessage; page.Validators.Add(validator); } } } To use this method just put the using MyExtensions; statement at the top of your code-behind of the page that you want to use it on. Then you can do the following: protected void btnSubmit_Click(object sender, EventArgs e) { try { // do some stuff li
validation on button or on another event. CustomValidator val = new CustomValidator(); val.IsValid = false; val.ErrorMessage = "Custom error message to add to the ValidationSummary"; this.Page.Validators.Add(val); https://maniish.wordpress.com/2010/11/24/add-custom-message-to-validationsummary-in-asp-net/ Like this:Like Loading...
