Answer 1

In VegTableViewmodel:

public IEnumerable Vegetables { get; set; }

In the Controller: Get vegetables list, and then pass it to the VegTableViewModel's Vegetables property.

viewmodel.Vegetables = vegetables .Select(d => new MultiSelectList(d.VegName));

In the View:

@Html.ListBoxFor(m => m.L, new MultiSelectList(Model.Vegetables.Select(d => d.Items))
