Apr 12, 2005 custom validator 04:34 PM|bosox04|LINK Hello All, I have an aspx page with several "requiredfieldvalidator" and one "customvalidator" for the checkbox. I use a "ValidationSummary" with the ShowMessageBox="true" to display a popup summary of all required fields. All error message from "RequireFieldValidator" are shown accordling, but not the error message from "CustomValidator". Anyone know why? and how to correct it? Thanks custom validator error Reply daver None 0 Points 178 Posts Re: How to show error mesage from "CustomValidator" to "ValidationSummary" control? Apr 12, 2005 06:06 PM|daver|LINK I assume your custom validator is doing server side work to determine the validity of the data, correct? If so, once you determine that the data is invalid, add the custom validator to you validation summary in your code behind. -- daver Reply ahooi99 None 0 Points 165 Posts Re: How to show error mesage from "CustomValidator" to "ValidationSummary" control? Apr 12, 2005 10:20 PM|ahooi99|LINK You can write your CustomValidation logic in client side by using the javascript. Then for your CustomValidator, set the ClientValidationFunction to your javascript function. It works as RequiredFieldValidator, without causing any postback..

pipeline with absolutely no pain. One of the controls that perfectly fits ASP.NET validation system is ValidationSummary. It's aim is to collect error messages for all validators of a specific validation group when they signalize there's an error in user input.The standard control works perfectly when dealing with client side validation. But it has a significant bug when doing server side validation with CustomValidator: no messages are displayed for failed controls.On the picture below you may see a screen shot of a Wizard page that shows user input errors being validated client side:In this sample mandatory fields can be easily validated client side. But what if you need to do server request to check something against DB? In this sample I'd like to check whether there're prices persisted to DB for all sites when a checkbox 'Same prices for all sites' is checked. The easiest way is to use the standard CustomValidator control and add necessary checks to CustomValidator.ServerValidate event (the control also perfectly works with async postbacks and UpdatePanels):protected void sitesCustomValidator_ServerValidate(object sender, ServerValidateEventArgs e){ if (samePriceCheckBox.Enabled) { e.IsValid = ..; // validation result }}But even though when custom server validation fails (there're no prices for all sites) in code behind the Page.Valid property is 'false' and there's an opportunity to block next wizard step - validation summary doesn't show the error message for the CustomValidator failed:The problem here is that ValidationSummary is only updated on postback to server. In the case when server side validation failed validators and their results are rendered to the response and NO ValidationSummary update occurs.To override this drawback the following script can be used (jQuery is required):$(document).ready(function () { var displayAlert = function () { if (typeof Page_Validators == 'undefined') return; var groups = []; for (i = 0; i < Page_Validators.length; i++){ var validationGroup = typeof Page_Validators[i].validationGroup == "undefined" ? "": Page_Validators[i].validationGroup; if (!Page_Validators[i].isvalid) { if (!groups[validationGroup]) { ValidationSummaryOnSubmit(validationGroup); groups[validationGroup] = true; } } } }; displayAlert(); Sys.WebForms.PageRequestManager.getInstance().add_endRequest(function () { displayAlert(); });});What it does is checking all validation controls on page load or async postback completion and triggering ValidationSummary updates for those validation groups that have failed validators.The script refe
