问题 Lets say I have form build in GWT, an UI-Binder, which implements Editor interface (com.google.gwt.editor.client.Editor) with two date fields (date from and to). Bean class is expected to have members: Date fromDate; // with getter and setter Date toDate; // with getter and setter And okay, while having bean class defined as written, there is no problem, but just after I add something like this: public boolean hasFromDate() { return fromDate != null; } I got compilation error (for example for

问题 MVC3 comes out of the box with JsonValueProviderFactory() which is very handy for binding incoming JSON to a model. Unfortunately, I can't figure out how to setup model contracts with names that differ from the incoming JSON. For example: [DataContract(Name = "session")] public class FacebookSession { [DataMember(Name = "access_token")] public string AccessToken { get; set; } [DataMember(Name = "expires")] public int? Expires { get; set; } [DataMember(Name = "secret")] public string Secret {

问题 I was trying to create custom model binder in my ASP.NET MVC 4 project. But i get stuck with IModelBinder iterfaces. There are three IModelBinder interfaces VS can find. In following namespaces. using System.Web.Http.ModelBinding; using System.Web.Mvc; using System.Web.ModelBinding; bool BindModel(HttpActionContext actionContext, ModelBindingContext bindingContext) object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext); bool BindModel

问题 I’m trying to build this: When I edit field on the left it should update the one on the right and vice-versa. Editing a value in an input field causes the text cursor to jump at the end of it. Typing "2" in the fahrenheit field gets replaced with 1.999999999999, as you can see on the screenshot. This happens because of the double conversion: view’s Fº → model’s Cº → view’s Fº.
