Bind enum to combobox

Question

Hi I have this enum type: public enum SchedActiveEnum { [Description(All)] All [Description(Y)] Y [Description(N)] N } What is the better way for bind it in a combobox? I would like to display the description but get the value. Thanks.

I gave up a long time ago trying to format code in the Post/Reply Box itself. Instead I either paste in code which has already been formatted directly from Visual Studio or prepare the formatted code initially in Notepad and then paste it in from there.

Resolved. private Dictionary _schedActive; public Dictionary SchedActive { get { if (_schedActive == null) { _schedActive = new Dictionary (); //Permette di visualizzare la Description dell'Enum var myList = Enum.GetValues(typeof(Definition.SchedActiveEnum)).Cast ().Select(value => new { value (Attribute.GetCustomAttribute( value.GetType().GetField(value.ToString()) typeof(DescriptionAttribute)) as DescriptionAttribute).Description } ); foreach (var item in myList) { _schedActive.Add((Definition.SchedActiveEnum)item.value item.Description); } } return _schedActive; } } in xaml: DataContext={StaticResource DomainDataViewModel} ItemsSource={Binding SchedActive} DisplayMemberPath=Value SelectedValuePath=Key Width=50> Thanks. OT. How can I format my code in this forum?

To display the Key i.e. the actual enum members rather than their Description attributes I think you'll need: DisplayMemberPath=Key SelectedValuePath=Value though I thought you said you wanted to display the Descriptions in your opening post?

Resolved with Dictionary: private Dictionary _schedActive; public Dictionary SchedActive { get { if (_schedActive == null) { _schedActive = new Dictionary (); var myList = Enum.GetValues(typeof(Definition.SchedActiveEnum)).Cast ().Select(value => new { value (Attribute.GetCustomAttribute( value.GetType().GetField(value.ToString()) typeof(DescriptionAttribute)) as DescriptionAttribute).Description } ); foreach (var item in myList) { _schedActive.Add((Definition.SchedActiveEnum)item.value item.Description); } } return _schedActive; } } in the Xaml: DataContext={StaticResource DomainDataViewModel} ItemsSource={Binding SchedActive} DisplayMemberPath=Value SelectedValuePath=Key Width=50> where DataContext is my ViewModel. One problem: the ComboBox returns me the value of Dictionary and not the Key? Why? Thanks.

There's some code in this thread to do something similar to that: http://codereview.stackexchange.com/questions/39163/loading-a-combobox-with-an-enum-and-binding-to-it In your case this code should work for WPF: comboBox1.ItemsSource = Enum.GetValues(typeof(SchedActiveEnum)) .Cast () .Select(value => new { (Attribute.GetCustomAttribute(value.GetType().GetField(value.ToString()) typeof(DescriptionAttribute)) as DescriptionAttribute).Description value }) .ToList(); comboBox1.DisplayMemberPath = Description; comboBox1.SelectedValuePath = value; comboBox1.SelectedIndex = 0;
