How to use SelectListItem for dropdown

[MKI-Miro]

Hi

I need to use dropdown. So for example i need to add this
public IEnumerable<SelectListItem> CreditCards { get; set;
to
CustomerViewModel
but SelectListItem is part of Microsoft.AspNetCore.Mvc.ViewFeatures.dll

Is it correct to add MVC dependency to Application project?

Thanks

Hi @MKI-Miro

Is it correct to add MVC dependency to Application project?

God no! You Application should not be aware of what kind of client is consuming it - web, mobile, windows, don't care. So, no dependency at all on it. The Application project should be ready to serve any kind of client.

About the SelectListItem...

Actually, this depends on you. You can extend the CustomerViewModel class in you presentation layer and add more properties to it.

You also can - but shouldn't - create the SelectListItem directly at your Razor view.

but I cannot add SelectListItem to CustomerViewModel.... (because of dependency to MVC)

so what is the solution?

[thiagolunardi]

You extend it.

At you UI.Web project, create a file /CustomViewModels/MyCustomerViewModel.cs

public class MyCustomerViewModel : CustomerViewModel
{
    public IEnumerable<SelectListItem> CrediCards { get; set; }
}

but CustomerAppService does not reference UI.Web

Ok, we are missing some info here.

What you have right now at your Application.ViewModels.CustomerViewModel?

Can you share the code here?

[MKI-Miro]

nothing :) it was just wondering how to do it. All I have is your code. So maybe you can extend your application with one dropdown.

[thiagolunardi]

But I already show you that with MyCustomerViewModel sample.

What you didn't get it?

Can we close your issue, @MKI-Miro ?
