Question

I am trying to ensure that my fields and page options are valid and on one page i want to check and see if an item is selected or not – which a selection is required to save.

I have the following:

in ViewEntry: public IList<Guid> Parties { get; set; }

in my ViewModel: public IEnumerable<Guid> PartiesSelected { get; set; }

Here is my ensure valid code:

public void EnsureValid(VisitEntry visitEntry)
    {
        var errors = new RulesException<VisitActivityEntryDTO>();

        if(visitEntry.Parties == null )
            errors.ErrorForModel(string.Format("No {0} selected", Kids.Resources.Entities.Party.EntityNamePlural));
        if (errors.Errors.Any())
            throw errors;
    }

and in my controller my Get Edit method when loading the page I have:

viewModel.PartiesSelected = visitEntry.VisitEntryParties.Select(v=>v.PartyId);

Is it possible in any way that i could possibly have:

viewEntry.Parties = viewModel.PartiesSelected

or

viewEntry.Parties = visitEntry.VisitEntryParties.Select(v=>v.PartyId);

I mainly want to have the selected party to show up in the list of Parties for the ViewEntry so when i validate.

Answer 1

 viewEntry.Parties = viewModel.PartiesSelected.ToList()
