问题 I created a custom Model binder working fine with all the properties. But the issue is I am missing the default modelbinding. I am using DataAnotations for my objects and I want to apply my custom model binder for Enums only. How can I achieve the custom Model binder along with default model binding. In the custom Model Binder, I have the code as following. public bool BindModel(System.Web.Http.Controllers.HttpActionContext actionContext, ModelBindingContext bindingContext) { var json =

问题 I need to know how to create a custom IModelBinder in MVC 4 and it has been changed. The new method that has to be implemented is : bool BindModel(HttpActionContext actionContext, ModelBindingContext bindingContext); 回答1: There are 2 IModelBinder interfaces: System.Web.Mvc.IModelBinder which is the same as in previous versions and hasn't changed System.Web.Http.ModelBinding.IModelBinder which is used by the Web API and the ApiController. So basically inside this method you must set the

问题 Does anyone have links to tutorials regarding the new IModelBinder in asp.net mvc beta? I can't get my head around it properly, so much has changed. Thanks 回答1: Take a look at the source of DefaultModelBinder. That'll give you some clues. 回答2: As Haacked points out the source for DefaultModelBinder is a good resource. It would be nice to see a related tutorial on http://www.asp.net/mvc though (hint... hint... at Haacked). For your convenience here is a direct link to the relevant source: http

问题 I'm trying to figure out model binding in current mvc6 (visual studio 2015 release candidate).

Extending Sanderson's custom mvc ModelBinder for an object stored in session

由 大兔子大兔子 提交于 2019-12-06 05:26:47
In his wonderful MVC book Steven Sanderson gives an example of a custom model binder that sets and retrieves a session variable, hiding the data storage element from the controller. I'm trying to extend this to cater for a pretty common scenario: I'm storing a User object in the session and making this available to every action method as a parameter. Sanderson's class worked ok when the User details weren't changing, but now i need to let the user edit their details and save the amended object back to the session. My problem is that I can't work out how to distinguish a GET from a POST other

I'm looking for a set of best practices to use when implementing IModelBinder . I've read three different MVC books and each one does some slightly different stuff in their implementations without any real explanation. The Hanselman, Haack, Guthrie, Conery book doesn't even mention IModelBinder Palermo recommends extending DefaultModelBinder rather than direct implementation of IModelBinder , but I don't really see how to leverage the benefits Sanderson mentions updating existing Model instances, as well as calling ModelState.SetModelValue() to follow convention. I just want to make sure that

ASP.NET MVC - Custom model binder able to process arrays

由 江枫思渺然 提交于 2019-11-28 07:47:01
I need to implement a functionality to allow users to enter price in any form, i.e. to allow 10 USD, 10$, $10,... as input. I would like to solve this by implementing a custom model binder for Price class. class Price { decimal Value; int ID; } The form contains an array or Prices as keys keys: "Prices[0].Value" "Prices[0].ID" "Prices[1].Value" "Prices[1].ID" ... The ViewModel contains a Prices property: public List<Price> Prices { get; set; } The default model binder works nicely as long as the user enters a decimal-convertible string into the Value input. I would like to allow inputs like
