问题 It's a classic login flow. The user can choose between 'new user' or 'existing user'. If the user is new, the name in the login box should validate against the server to see if the username is unique, if it's an existing user this check will be skipped since we expect the username to be taken already (ofcourse). I added a [Remote] attribute on the viewmodel and added the radiobutton for new/exiting user as 'additional fields'. This way the remote validation will just return true if it's an

问题 In an MVC3 app, using jquery unobtrusive validation, and a view/model with a [Remote] validator: I am trying to disable the submit button and display a wait icon during remote validation, and when a valid form is submitted to the server. I thought I had it nailed until I tried it in IE8. The problem was, GC and FF were not firing the form's submit event when the form was invalid, so I just disabled the submit button during this event. However IE8 is firing this event when the form is invalid,

问题 I am developing an MVC 5 app using EF 6 database first approach. I have a certain validation which is required for fields in many of my models. I am using remote validation for validating them. Since it was being used in a lot of models so I am trying to go for a generic method. For that matter I made an Interface named IEntity which includes all properties being used in my models. Then I did the following for my Validation method: [HttpPost] public JsonResult UniqueCheck<T>(T code) where T :
