Model is null on Post to Controller

[Emmsa]

Hello, 

I 'm have a view based on a ViewModel. This View Model has one Complex Property which is a collection.

public class ParentViewModel
    {
        public int Id { get; set; }

    public int Description  { get; set; }

        public List<SecurityListViewModel> secList { get; set; }
    }
} 

[Emmsa]

My apologies! I have unintentionally published the post and now it doesn't allow me to edit it.

Here is my question again:

I have a view based on a ViewModel. This View Model has one complex property which is a collection. And I have a grid for CRUD operations of that collection.

When ever I submit this form the list is always null in the controller.

I found this stackoverflow post with a similar scenario but in .NET MVC:

http://stackoverflow.com/questions/14555137/submit-form-with-kendo-mvc-grid-and-other-elements

But I don't really like that solution.

Now with .NET Core, is there a better solution?

Thanks in advance

Hi,

If you want to submit the changes within the Grid on submitting a Form you will have to use the suggested approach in the forum thread. The same approach is demonstrated in the following HowTo article:

• http://docs.telerik.com/aspnet-mvc/helpers/grid/how-to/editing/post-grid-with-form

Another solution would be to configure the DataSource of the Grid to use AJAX binding and handle the changes within the AJAX requests:

Hope this helps.
