I have some viewdata that is generated by going through my repository to the database to grab some scheduling info. When the information is stored in the Viewdata, I noticed that the viewdata is enumerated. How could I access the enumerated items and generate a table/list based on the viewdata? Most of the information just needs to be sp...
In my controller I create a list of SelectListItems and store this in the ViewData. When I read the ViewData in my View it gives me an error about incorrect types. If I manually cast the types it works but seems like this should happen automatically. Can someone explain? Controller: enum TitleEnum { Mr, Ms, Mrs, Dr }; var titles = n...
I am attempting to implement a custom locale service in an MVC 2 webpage. I have an interface IResourceDictionary that provides a couple of methods for accessing resources by culture.

Hello, I ran into a situation that I have never ran into before, hoping someone can help. I have a client that wants to be able to run a totally new ad-hoc report, or pick one from a drop down list. When chosen, it does a foreach through filter criteria objects nested in the report object. I had some initial trouble, because there was...

Should the viewmodel contain a list for the dropdownlist or should I pass the data for the dropdownlist by using ViewData? When schould I use ViewData and when don't I should use...
I'm by no means lazy, but already 2 days overdue on our current sprint in my first ever MVC project, so I've been using the Add View Wizard to generate strongly typed views, but now that I have started using ViewData classes as view models, the wizard generates fields for ViewDataBase, and not my derived ViewData. I think that the deriv...

[Autho...
Assuming you wanted to develop your Controllers so that you use a ViewModel to contain data for the Views you render, should all data be contained within the ViewModel? What conditions would it be ok to bypass the ViewModel? The reason I ask is I'm in a position where some of the code is using ViewData and some is using the ViewModel. I...
If in my controller: public ActionResult Index() { //no code implied return View; } Then in the view that is returned: <%if(ViewData["SomeString"].ToString() != "True") {%> show this <%}%> I will get an error at runtime because of an object reference having no object. However inside of a page where I do: <%if(Request.Qu...

Yes, I know that in ASP.NET MVC you have to use ViewModels. But I'm tired of writing countless amounts of ViewModel classes. Besides I'd like to just pass the Validation model to the view, instead of that I have to pass the whole ViewModel, so I get ugly code like Html.TextBoxFor(m => m.TopicModel.Title) Instead of Html.TextBoxFor(m...
I like using Models for validation <!-- ViewPage --> <%@ Page Language="C#" Inherits="ViewPage<TopicModel>" %> ... <%= Html.TextBoxFor(m => m.Title) %> ... <%= Html.TextBoxFor(m => m.Description) %> // Controller [HttpPost] public ActionResult NewTopic(TopicModel model) { // validate } It works great, but when I need to p...
I have the following code: public ActionResult Foo() { var a = "a"; return View(new FooModel { A = a}); } [HttpPost] public ActionResult Foo(....) { // I need to set all the values of the ViewModel again, not to get a null exception in the view return View(new FooModel { A =...
In my understanding, the ViewModel pattern was designed to pass all the relevant data to View because 1) the view shouldn't perform any data retrieval or application logic and 2) it enables type-safety, compile-time checking, and editor intellisense within view templates. Since dynamic expressions are defined at runtime, does this mean ...
I dont know where is my problem to access EntryList in ViewData. <%= Html.RenderPartial("LogOnControl", new NISE.Web.TestForum.Views.Shared.PaginationViewData() { PageIndex = ViewData.*EntryList*.PageIndex, TotalPages = ViewData.*EntryList*.TotalPages, PageActionLink = Url.Action("List","Entry", new { category = Vi...
