the Page.Validators collection. Dim err As New CustomValidator err.ValidationGroup = "MyGroup" err.IsValid = False err.ErrorMessage = "The password is invalid" Page.Validators.Add(err) Unlike adding the CustomValidator to the markup, this method allows you to add any number of arbitrary error messages based on server-side business logic. Note that you can also add it to the page directly, but there are a couple of rules to follow: You must add the control to the same naming container as the controls of the validation group. If you don't want the validation message to appear in a random position in the page, you will either have to add the validator to a specific container or you will need to supress it using a CSS class or style. You can also create a custom class and implement IValidator, which enables you to add the message with one line of code, but this method doesn't support Validation Groups. Per Anders Fjeldstad's suggestion, here is a set of handy extension methods. Imports Microsoft.VisualBasic Imports System.Runtime.CompilerServices Public Module PageExtensions
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 happens in a Domain Service Class or

your Custom BLL for example? These exceptions will by default be caught by the validationsummary message application and show as a nasty error to the user, or go to the error page. This is hardly the desired behavior validationsummary custom message for a validation error. First I like to change the default behavior of bubbling up to the application to be caught to being handled at the button or page level. To do this I put a http://stackoverflow.com/questions/777889/on-postback-how-can-i-add-a-error-message-to-validation-summary 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 has a Validators property that all validators are automatically added to when you put them on your .aspx page. http://justgeeks.blogspot.com/2010/11/adding-item-to-validationsummary.html 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 like call my BLL that may throw an exception } catch (Exception ex) { if (ex.Message == "Some key string I want to handle") { Page.AddValidationSummaryItem("Password must be at least 6 chara
