Add Custom Validator To Validation Summary
control and add it directly to 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.

J InceFebruary 28, 200819 0 0 0 For a while now I’ve used this handy bit of code to add a message programmatically to a Validation Summary control, without associating it with a Validator. I’ve no idea where it came from – perhaps my head, perhaps someone cleverer than https://blogs.msdn.microsoft.com/simonince/2008/02/28/adding-messages-to-a-validation-summary/ I… so if it was from you, shout up! I was asked how to do this today by a customer, so I felt inspired to blog it. Anyway, sometimes you get an error from your business logic that it just isn’t practical to have pre-validated. For example, when adding a new employee to a database, perhaps the employee name has a UNIQUE constraint on it. Validating this up front might not be easy… So if I get an to validation error back from my business logic (either in the form of a list of validation errors, or in the worst case scenario as an exception) how do I display this message to the user? Well it turns out this is quite easy – just add a validator that is reporting itself as “IsValid = false” to the Page.Validators collection. Consider the following class; public class ValidationError : IValidator { private to validation summary ValidationError(string message) { ErrorMessage = message; IsValid = false; } public string ErrorMessage { get; set; } public bool IsValid { get; set; } public void Validate() { // no action required } public static void Display(string message) { Page currentPage = HttpContext.Current.Handler as Page; currentPage.Validators.Add(new ValidationError(message)); } } (Note: This is usingautomatic properties - a C# 3.0 feature. Alter the code to use standard properties if you're using an earlier version of .NET) This immediately allows me to use the following code; ValidationError.Display("Oops, some error occurred."); Succinct, eh?! Here’s a shot of it in action;

Reply KA says: March 28, 2008 at 1:15 pm This works well - thanks for the tip. Reply Nicole says: April 7, 2008 at 2:06 pm Something similar to this can be done by adding a CustomValidator dynamically when the error occurs. For example: CustomValidator cv = new CustomValidator(); cv.IsValid = false; cv.ErrorMessage = "The error to display."; this.Page.Validators.Add(cv); Reply Simon J Ince says: April 8, 2008 at 5:13 am Nicole; Very true, I like it. You could easily wrap this up in a s
