How to map IEnumerable<SelectListItem> to IList<> for ListBox
- by Superhuman
I have two classes. Class1 and Class2.
public class Class1{
...
public virtual IList<Class2> Class2s{get;set;}
...
}
public class Class2{
...
public virtual IList<Class1> Class1s{get;set;}
...
}
The view contains
<%=Html.ListBox("Class2s",
ViewData.Model.Class2s.Select(
x => new SelectListItem {
Text = x.Name,
Value = x.Id.ToString(),
Selected = ViewData.Model.Class1.Class2s.Any(y => y.Id == x.Id)
})
They have many to many mapping. I have a ListBox in Class1 view which displays Class2. How to map the output of the ListBox back to IList Class2s property of Class1? I am able to display the values in the ListBox but unable to map back the SelectListItem to IList.
