How to use anonymous list as model in an ASP.NET MVC partial view?

由 丶灬走出姿态 提交于 2019-12-09 03:29:26
问题 I have a list of Contact objects, from which, I just want a subset of attributes. So I used LINQ projection to create an anonymous list and I passed that to a partial view. But when I use that list in partial view, compiler says that it doesn't have those attributes. I tried the simplest case as follow, but still I have no chance to use an anonymous object or list in a partial view. var model = new { FirstName = "Saeed", LastName = "Neamati" }; return PartialView(model); And inside partial

Using ViewModels instead DTOs as the result of a CQRS query

由 戏子无情 提交于 2019-12-08 19:16:31
问题 Reading a SO question, I realized that my Read services could provide some smarter object like ViewModels instead plain DTOs. This makes me reconsider what information should be provided by the objects returned by the Read Services Before, using just DTOs, my Read Service just made flat view mapping of a database query into hash like structure with minimum normalization and no behavior. However I tend to think of a ViewModel as something "smarter" that can have generated information not

MVC map to nullable bool in model

由 社会主义新天地 提交于 2019-12-08 15:04:50
问题 With a view model containing the field: public bool? IsDefault { get; set; } I get an error when trying to map in the view: <%= Html.CheckBoxFor(model => model.IsDefault) %> Cannot implicitly convert type 'bool?' to 'bool'. An explicit conversion exists (are you missing a cast?) I've tried casting, and using .Value and neither worked. Note the behaviour I would like is that submitting the form should set IsDefault in the model to true or false. A value of null simply means that the model has

Who should create view model instances in MvvmCross

由 ▼魔方 西西 提交于 2019-12-08 08:52:22
问题 Just to make it clear: I know MvvmCross is very flexible about where and how view models can be created. My question is more about proper separation of concerns, to simplify design of complex cross-platform applications. Consider we have an app with customer list and customer details. On iPad and Surface the list and details are shown on the same page, but on smaller devices customer list and details for a selected customer are split between separate pages. So we have a PCL with
