Question

I have next enumeration

Enum rcCategory
{
  Incoming,
  Internal,
  Outgoing
}

and I have property “categories” in my class which has rcCategory[] type.

I would like to bind this property to the listBox. I use next code for this

MyListBox.SetBinding (ListBox.ItemsSource, new Binding {Source= myClass.categories});

But this code doesnt work as expected.
How Can I do this. My listBox always is empty but source property has value

See Bea Stollnitz top ranked article on it.
In short you need to bind to an ObjectProvider which calls the static method Enum.GetValues( typeof(YourEnum) ) to return the list.

Update: Sorry got a slight speedreading issue. This one is easier.. Verified that it works. Recommended: Find up a copy of ProgrammingWPF and go thru the DataBinding chapter…

XAML:

<ListBox DockPanel.Dock="Left" ItemsSource="{Binding EnumArrayProp}"/>

Codebehind:

public partial class Window1 : Window
   {
       public rcCategory[] EnumArrayProp
       {
           get; set;
       }
       public Window1()
       {
           InitializeComponent();

           this.EnumArrayProp = new rcCategory[] { rcCategory.Incoming, rcCategory.Incoming, rcCategory.Outgoing };

           this.DataContext = this;

       }
