Add Message To Validationsummary Mvc
I am doing something like below on a web forms application; protected void button_transfer_search_Click(object sender, EventArgs e) { Page.Validate("val1"); if (!Page.IsValid && int.Parse(txtArrivalDateTrf.Text) + 5 < 10) { return; } also, I have following code on my aspx file;
J InceFebruary 28, 200819 Share 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 I… so add error to validationsummary if it was from you, shout up! I was asked how to do this today by add message to validation summary javascript 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 validationsummary message 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 error back from my http://stackoverflow.com/questions/5911789/adding-error-message-to-validation-summary-from-code-behind 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 ValidationError(string message) { ErrorMessage https://blogs.msdn.microsoft.com/simonince/2008/02/28/adding-messages-to-a-validation-summary/ = 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 static helper method similar to my approach above. I guess the advalidation on button or on another event. CustomValidator val = new CustomValidator(); val.IsValid = false; val.ErrorMessage = "Custom error message https://maniish.wordpress.com/2010/11/24/add-custom-message-to-validationsummary-in-asp-net/ to add to the ValidationSummary"; this.Page.Validators.Add(val); Like this:Like Loading...

Or at least I didn't think that there was, but it turns out that it's quite simple: 1: RequiredFieldValidator Validator = new RequiredFieldValidator(); 2: Validator.ErrorMessage = "This is your error message"; 3: Validator.ValidationGroup = "Group1"; 4: Validator.IsValid = false; 5: Validator.Visible = false; 6: Page.Form.Controls.Add(Validator); The error message and the validation group needs to be changed but basically this just creates a required field validator. It then says that the validator isn't valid and makes it invisible. However since we have a ValidationSummary object, it will show up there (assuming we set up the validation group properly). That's all there is to it. Anyway, I hope this helps out someone so you're not banging your head against a wall like I was. So try it out, leave feedback, and happy coding.
