Silverlight 2 Error Code: 4004
- by jkidv
Hey guys/gals. I have a silverlight 2 app that has an ObservableCollection of a class from a separate assem/lib. When I set my ListBox.ItemsSource on that collection, and run it, I get the error code: 4004 "System.ArgumentException: Value does not fall within the expected range."
Here is part of the code:
public partial class Page : UserControl
{
ObservableCollection<Some.Lib.Owner> ooc;
public Page()
{
ooc = new ObservableCollection<Some.Lib.Owner>();
Some.Lib.Owner o1 = new Some.Lib.Owner() { FirstName = "test1" };
Some.Lib.Owner o2 = new Some.Lib.Owner() { FirstName = "test2" };
Some.Lib.Owner o3 = new Some.Lib.Owner() { FirstName = "test3" };
ooc.Add(o1);
ooc.Add(o2);
ooc.Add(o3);
InitializeComponent();
lb1.ItemsSource = ooc;
}
}
But when I create the Owner class within this same project, everything works fine.
Is there some security things going on behind the scenes? Also, I'm using the generate a html page option and not the aspx option, when I created this Silverlight 2 app.
