问题 I am working on an MVC 4 project that is constantly showing the ValidationMessage even on a simple GET method that does no validation or model binding of complex types: //location/{locationId}/announcement [HttpGet] public ActionResult LocationMakeAnnouncement(int locationId) { var pageViewModel = this.BuildLocationMakeAnnouncementViewModel(locationId); return View(pageViewModel); } The BuildLocationMakeAnnouncementViewModel only builds up the ViewModel and doesn't touch the ModelState.

问题 I have an ASP.NET MVC 4 App that uses the jQuery.validation.js plugin and MVC's jQuery.validation.unobtrusive.js . I use data annotations on my view model to validate a textbox's input to be an integer.

问题 I have a form with some controls. There is a button on the form which loads a partial view. Inside the partial view, there are two required field textboxes along with a button. And when its clicked, I need to display error messages only for textboxes which are inside the partial view, but not for the fields in the actual form.

问题 I have a form which loads a div on client side. I have hard coded textbox controls with all validation attributes, similar to what it renders when loaded from server. Inside the div there is submit button, but when I click on submit all validations messages on the form are displayed. I just need only the div elements validation messages to be shown. Telerik Grid control in ajax mode, does similar thing, i.e., appends textboxes with hardcoded validation attributes on client side, but it
