[Solved] pass view from Controller to DefaultDataItem

[Tomas]

There is possibility to assign default values to new item model like this

Editable(editing => editing.DefaultDataItem(new UserViewModel { ProductId = 0 }))

But there is one problem with this approach. My UserViewModel contain IEnumerable<SelectListItem> and other properties which should be populated in Controller using DataAccessRepository  and not in View directly. Also it is bad practice to write code in View.

So how to pass new UserViewModel  to DefaultDataItem from controller while user click Insert in Grid?

I found the answer in your question, transmit via the Controller the initial value :

Editable(editing => editing.DefaultDataItem((UserViewModel)ViewData["InitialUserView"]))

The ViewData usage is bad practice in MVC and should be avoided if possible. ViewData is in anti-pattern of MVC.
Why Telerik Grid do not call Controller Action while Inserting new record? It would be easy and more MVC friendly  to pass instantiated ViewModel with default values through Action.

I'm not a here to talk about rhetoric, Microsoft MVC 3 use internally ViewData and ViewBag, and for this structure it is common to use them.

Also you talk about ViewModel where it is MVVM pattern, if you want to call a .Editable(e=>e.TemplateName("MyTemplate")) 
where MyTemplate call an action in the controller, don't know if this will work, but you can try.

Otherwise if you don't want to use ViewData and ViewBag you can use your Model

Editable(editing => editing.DefaultDataItem(Model.InitialUserView))  

your Model could be like this : 
public class MyModel
{
public IEnumerable<UserViewModel>  Data {get; set}
public UserViewModel InitialUserView{get;set;}
}

if you use server side :
Html.Telerik().Grid(Model.Data)

else
Html.Telerik().Grid<UserViewModel>()


Last, if you want telerik change it's grid i suggest you to send a PITS request.

I can't use this code because Child Grid use Ajax binding and I can't transfer ViewData on Ajax binding. I can initialize ViewData when web page is builded on Index action but in that time I do not have values for InitialUserView because they depend on Master grid selection.

Not sure if I understand you correctly but Action is never called when editable template is loaded.

Editable(editing => editing.Mode(GridEditMode.PopUp).TemplateName("AdminUserForm"))

The action below is never called.

        [GridAction]
        public ActionResult AdminUserForm()
        {
            return View();
        }

In your template you can call an action :

@Html.Action("Action", "Controller")

You mark my post as answer, do you find a way to solve your problem? could you share it please?

edit: when i talk of "Template", i'm talking of a partialview in views/shared/EditorTemplates
