问题 I have a form with two fields that need to be equal (password and password confirmation). I've created a class attribute to check that and on server side it works great. On the client side it does nothing. I need the message to appear in ValidationSummary ("Password repeated" needs to be the same as "Password"). I realized that the easiest way to check these fields would be adding the rule manually to window.mvcClientValidationMetadata. I was trying to do that but nothing worked. My code: <%

问题 I am trying to add new records in my DB to multiple related tables that all have an ID as PK and IDs of other tables as FKs. I've based my approach on the NerdDinner tutorial but I can't find any examples on how to add new records in the DB when more than one table is involved. ModelState.IsValid fails when trying to save the new records for some reason. I tried adding them as shown below and update each table seperately but that doesn't work. I am new to MVC, .NET and programming in general

问题 Prior to using a ViewModel, I could easily pass the "soon to be edited" object directly to the view without needing to fuss over setting individual properties etc as the View conveniently accepted the Employee type directly.. [HttpGet] public ActionResult EditEmployee(int? id) { EmployeeRepository ER = new EmployeeRepository(); Employee SomeEmployee = ER.GetEmployee(id.Value); if(SomeEmployee!=null) return View(SomeEmployee); But now I'm using a ViewModel with DataAnnotations attributes

问题 My confusion stems from the fact I am using 2 different walkthroughs on building mvc applications, namely: Steven Sanderson's pro asp.net mvc and the online mvc music store. The former creates a domain model, placing the entity model in there along with repositories, while the music store demo places the entity model in the mvc model folder. Which of these is the best approach. Should the entity model and associated repositories exist in a separate domain layer, or in the MVCs model folder.

问题 I have form that has several forms inside of it in asp.net mvc. The nested forms are using ajax helpers and are ajax forms. The forms that are nested ALWAYS post to the original form's action, not their action. Why? Why can't I have multiple forms on one page? 回答1: You can have as many forms you like on a page, but you can't nest them. It has nothing to do with ASP.NET or MVC, it's the HTML form tag that doesn't allow nesting. If you try to nest forms, the browser will ignore the inner form
