model-binding

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 { get; set; } [DataMember(Name = "session_key")] public string Sessionkey { get; set; } [DataMember(Name

I want to send a complex object with a nested array in the uri to an MVC action method in a GET request. Consider the following code: public ActionResult AutoCompleteHandler([FromUri]PartsQuery partsQuery){ ... } public class PartsQuery { public Part[] Parts {get; set; } public string LastKey { get; set; } public string Term { get; set; } } $.ajax({ url: "Controller/AutoCompleteHandler", data: $.param({ Parts: [{ hasLabel: "label", hasType: "type", hasIndex : 1 }], LastKey : "Last Key", Term : "Term" }), dataType: "json", success: function(jsonData) { ... } }); This works just fine and binds

Is there any issues with modelbinding IEnumerable types to an MVC POST? Some properties in my Model are not being bound upon a post to an action. Seems that properties on the model like strings are ok, but my IEnumerable is what is not being bound. Here's a snippet of my code: <%: Html.TextBoxFor(m => m.ResponseInfo.SubsetInfo.Test) %> <% for (int i = 0; i < Model.ResponseInfo.SubsetInfo.BandAvailabilities.Count(); i++) {%> <%: Html.TextBoxFor(m => m.ResponseInfo.SubsetInfo.BandAvailabilities.ToArray()[i].BandName) %> <% } %> And here is what those properties look like in the model: public

UPDATE: Problem Solved. Darin Dimitrov's answer contains a link to another, related question. One of the proposed solutions on that page ended up working for us. Original Question The code sample below works in MVC 2 but throws an exception in MVC 3. Does anyone know why MVC 3 introduced this breaking change? Is there a way to get this working in MVC 3 while still allowing me to describe the viewmodel as an Interface from within the view? There is another related question on StackOverflow, but it doesn't give me any info as to why there is a difference between MVC 2 and MVC 3. Model public

I know that in knockout has the ability to specify class from observable property, like this: <div data-bind="css: Color " > Knockout also provides the ability to specify conditional class rendering like this: <div data-bind="css: { 'my-class' : SomeBooleanProperty }" > But which markup should be specified if i need those features of knockout css binding together? I tried this, but with no luck: <div data-bind="css: { Color, 'my-class' : SomeBooleanProperty }" > I have got the error: Error: Unable to parse bindings. SyntaxError: Unexpected token ,; I not found any example in google or in

I am rendering key:value object array with ng-repeat like this: <div ng-controller="mainCtrl"> <div ng-repeat="record in records"> <div ng-repeat="(key, value) in record"> <input ng-model="key" />: <input ng-model="value" /> </div> </div> </div> JS: var mainCtrl = function($scope){ $scope.records = [ {'key1':'val1'}, {'key2':'val2'} ]; } Problem is that keys and values cannot be updated through input tags. For some reason it becomes one way binding after making ng-repeat iterate over (key,value). Fiddle: http://jsfiddle.net/BSbqU/1/ How can I make it a two way binding? Or should I approach

If I do in a template of a component something like: <input [(ngModel)]="myProperty"></input> then it works, but if I do it with a function in my component it does not: <input [(ngModel)]="getMyProperty()"></input> Here is the plunkr. Tested on RC6. Why? Try this construction <input [ngModel]="getMyProperty()"></input> use only square brackets. 来源： https://stackoverflow.com/questions/39468450/ngmodel-with-a-bind-function-not-working-in-ng2

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(ModelBindingExecutionContext modelBindingExecutionContext, ModelBindingContext bindingContext); All related classes like

I have been scouring the internet trying to find a way to accomodate dashes from my form elements into the default model binding behavior of ASP.NET's Controllers in MVC 2, 3, or even 4. As a front-end developer, I prefer dashes in my CSS over camelCase or underscores. In my markup, what I want to be able to do to is something like this: <input type="text" name="first-name" class="required" /> <input type="text" name="last-name" class="required" /> In the controller, I would be passing in a C# object that would look like this: public class Person { public string FirstName { get; set; } public
