model-binding

My main view model has a collection of ChildViewModel. In the view, I loop over the collection and call EditorFor(), like so: @for (int i = 0; i < Model.Children.Count; i++) { @Html.EditorFor(m => m.Child[i]); } The editor template looks like: @model ChildModel @using (Html.BeginForm("EditChild", "MyController")) { @Html.HiddenFor(m => m.ChildId) @Html.TextBoxFor(m => m.ChildName) } This will generate markup where each children is in a separate form, and each such form will have an input control with name like Child[0].ChildName. I use a separate form for each children, as the children will be

I have a page that is made up of many user controls. The view model for this page is rather complex. public class ComplexViewModel { public ObjectA ObjectAProperty { get; set; } public List<Things> ListOfThings { get; set; } public List<ThingCategories> ListOfThingCategories { get; set; } public List<ThingTypes> ListOfThingTypes { get; set; } public List<ThingOptions> ListOfThingOptions { get; set; } public int ChosenThingCategoryId { get; set; } public int ChosenThingTypeId { get; set; } public int ChosenThingOptionId { get; set; } public OtherObject ObjectData { get; set; } } This page also

I was researching something and came across this blog post at buildstarted.com about model binders. It actually works pretty darn well for my purposes but I am not sure exactly whats going on behind the scenes. What I did was create a custom ModelBinder called USerModelBinder : public class UserModelBinder : IModelBinder { public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { ValueProviderResult value = bindingContext.ValueProvider.GetValue("id"); MyEntities db = new MyEntities(); User user = db.Users.SingleOrDefault(u => u.UserName == value

If I have a class similar to this: public class Person { public string firstName { get; set; } public string lastName { get; set; } public Pet myPet { get; set; } } When I create a custom model binder, the Post from my form will not be sending in a Pet, it would send in data like this: firstName: "myFirstName" lastName: "myLastName" myPet: "myPetsName" Since the Pet's name is passed in, and not the actual Pet object, the Pet object needs to be retrieved from within the model binder. My question is, should the model binder be interacting with the Service Layer, the Repository Layer, or should

I'd like to use model binding to keep my controllers looking cleaner, you can see how much nicer it is using model binding: public ActionResult Create(Person personToCreate) { //Create person here } vs public ActionResult Create(string firstName, string lastName, string address, string phoneNum, string email, string postalCode, string city, string province, string country) { //Create person here } When doing model binding, we can just use a form with the correct names in the Html.TextBox("") What about jquery? How can I make sure that when I do a $.post(url, data, callback, dataType) or a $

I am using MVC3 razor. I have a scenario where I have to use a partial view multiple times on the same parent view. The problem I am having is that when the Parent View gets rendered, it generates same names and ids of the input controls within those partial views. Since my partial views are binded to different models, when the view is posted back on "Save" it crashes. Any idea how can i make the control id/names unique, probably some how prefix them ? Awaiting Nabeel Personally I prefer using editor templates, as they take care of this. For example you could have the following view model:

I want to enforce that all dates in my system are valid and not in the future, so I enforce them inside the custom model binder: class DateTimeModelBinder : IModelBinder { public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName); try { var date = value.ConvertTo(typeof(DateTime), CultureInfo.CurrentCulture); // Here I want to ask first if the property has the FutureDateAttribute if ((DateTime)date > DateTime.Today) { bindingContext.ModelState.AddModelError(bindingContext
