Question

I am trying to return records from the program table that match the items in passed list but I am getting the following error:

Argument type ‘System.Nullable’ is not assignable to parameter type ‘System.Web.UI.WebControls.ListItem’

void PopulateEvents(List<ListItem> programs)
{
    var rows = from table in db.Events.AsEnumerable()
               where programs.Contains(table.ProgramID)
               select Events;
}

Answer 1

void PopulateEvents(List<string> programs)
{
    var rows = db.Events.Where(i => programs.Contains(i.ProgramID)).Select(i => db.Events);
}
