MVC 4 ignores DefaultModelBinder.ResourceClassKey

阅读更多关于 MVC 4 ignores DefaultModelBinder.ResourceClassKey

问题 Adding a resource file to App_GlobalResources with a PropertyValueRequired key and changing DefaultModelBinder.ResourceClassKey to the file name has no effect on MVC 4. The string The {0} field is required is never changed. I don't want to set the resource class type and key on every required field. Am I missing something? Edit: I've made a small modification on Darin Dimitrov's code to keep Required customizations working: public class MyRequiredAttributeAdapter : RequiredAttributeAdapter {

ASP.NET MVC 3 Model Binding Resources

阅读更多关于 ASP.NET MVC 3 Model Binding Resources

问题 I am looking for a good resource that describes very thoroughly how model binding works with ASP.NET MVC 3 (or to a lesser extent, MVC 2) and different approaches. I have not been able to find any good resources on this topic, except bits and pieces there. The information on the net is more about "how to do X" than explaining how the internals of model binding work. Any recommendations? Book recommendations are fine as well. 回答1: Take a look: ASP.NET MVC Model Binding - Part1 and Part2 http:/

Binding HttpPostedFileBase using Ajax.BeginForm

阅读更多关于 Binding HttpPostedFileBase using Ajax.BeginForm

问题 I have a form which binds a model and a file upload using the default binder for HttpPostedFileBase. This works fine when using Html.BeginForm(). However, I wanted to perform the same action using AJAX so I replaced this with Ajax.BeginForm() changing the parameters accordingly. The model still binds correctly, however I can't get the file upload to bind to the HttpPostedFileBase. This binds the model and the file upload: <% using (Html.BeginForm("MapUpdateColumns", "RepositoryAdmin",

ASP.net MVC - Model binding excludes class fields?

阅读更多关于 ASP.net MVC - Model binding excludes class fields?

问题 In a recent project - i've hit an unexpected snag. A class with simple public fields (note not properties) doesn't seem to want to play nice with the ASP.net MVC 3.0 model binder. Is this by design? besides changing the fields to properties - any options here? update The reason for the simple fields (instead of properties) is because I'm working with a shared library between MVC and a Script Sharp project. Script sharp supports properties - but it becomes a mess with javascript in the view

Remote Validation for LIST of MODELs

阅读更多关于 Remote Validation for LIST of MODELs

I used the following tutorial: http://msdn.microsoft.com/en-us/library/gg508808%28VS.98%29.aspx And everything seemed fine, but in my case, string Username always comes back null. After tonnes of research, I found everyone discovered BIND Prefixes. That would be great in many circumstances, but not this one. I should note all properties and names line up, however in my for loop, the EditorFor creates a [i].Username field and this doesn't map to any model property. QUESTION: I think I want to map [i].Username to Username where i is any number from 0-infinity, so when it GETS, the value is

How does MVC 4 List Model Binding work?

阅读更多关于 How does MVC 4 List Model Binding work?

If I want a set of inputs in a form to bind to a List in MVC 4, I know that the following naming convention for input name attributes will work: <input name="[0].Id" type="text" /> <input name="[1].Id" type="text" /> <input name="[2].Id" type="text" /> But I am curious about how forgiving the model binder is. For example, what about the following: <input name="[0].Id" type="text" /> <input name="[3].Id" type="text" /> <input name="[8].Id" type="text" /> How would the model binder handle this? Would it bind to a List of length 9 with nulls? Or would it still bind to a List of length 3? Or would
