Populating a combo box with values from an enum

Question

I've got the enum like so.

enum Beep {A, B, C }

Now, I wish to populate my combo box with these values as follows (the idea is to follow other's example ).

<ComboBox x:Name="comboBox1" 
          ...
          ItemsSource="Binding Source={StaticResource Beep}" />

However, the binding gets a little bit too static and gives me literally the exact string I'm putting in. What did I do wrong and how do I resolve it?

I've also tried following the hint I got to add something like this. To no avail, though.

public List<Beep> Beepies
{
  get
  {
    return new List<Beep>{ Beep.A }
  }
}

What more can be done about it? I can get the values into the box if I bind in the code behind by the below. But that's not the point - I wish to XAMLize the approach.

comboBox1.ItemsSource = Enum.GetValues(typeof(Beep));

Answer 1

You have to bind using a collection. Try creating a List<Beep> .

OR

Create a converter that enumerates the enum :

public class EnumConverter : IValueConverter
{
  public object Convert(object value, ...)
  {
    return Enum.GetValues(value.GetType());
  }
}

You can then use this converter in the binding to XAMLise the approach:

<!-- Put this in resources somewhere -->
<Converters:EnumConverter x:Key="MyEnumConverter"/>

<!-- Change your binding to include the new converter -->
<ComboBox x:Name="comboBox1" 
          ...
          ItemsSource="Binding Source={StaticResource Beep}, 
                       Converter={StaticResource MyEnumConverter}" />
