  1. PODatabinding an enum property to a ComboBox in WPF
    text
    copied!<p>As an example take the following code:</p> <pre><code>public enum ExampleEnum { FooBar, BarFoo } public class ExampleClass : INotifyPropertyChanged { private ExampleEnum example; public ExampleEnum ExampleProperty { get { return example; } { /* set and notify */; } } } </code></pre> <p>I want a to databind the property ExampleProperty to a ComboBox, so that it shows the options "FooBar" and "BarFoo" and works in mode TwoWay. Optimally I want my ComboBox definition to look something like this:</p> <pre><code>&lt;ComboBox ItemsSource="What goes here?" SelectedItem="{Binding Path=ExampleProperty}" /&gt; </code></pre> <p>Currently I have handlers for the ComboBox.SelectionChanged and ExampleClass.PropertyChanged events installed in my Window where I do the binding manually.</p> <p>Is there a better or some kind of canonical way? Would you usually use Converters and how would you populate the ComboBox with the right values? I don't even want to get started with i18n right now.</p> <p><strong>Edit</strong></p> <p>So one question was answered: How do I populate the ComboBox with the right values.</p> <p>Retrieve Enum values as a list of strings via an ObjectDataProvider from the static Enum.GetValues method:</p> <pre><code>&lt;Window.Resources&gt; &lt;ObjectDataProvider MethodName="GetValues" ObjectType="{x:Type sys:Enum}" x:Key="ExampleEnumValues"&gt; &lt;ObjectDataProvider.MethodParameters&gt; &lt;x:Type TypeName="ExampleEnum" /&gt; &lt;/ObjectDataProvider.MethodParameters&gt; &lt;/ObjectDataProvider&gt; &lt;/Window.Resources&gt; </code></pre> <p>This I can use as an ItemsSource for my ComboBox:</p> <pre><code>&lt;ComboBox ItemsSource="{Binding Source={StaticResource ExampleEnumValues}}"/&gt; </code></pre>
