Databinding an enum property to a ComboBox in WPF

📝 Tech Blog: Databinding an Enum Property to a ComboBox in WPF 🖥️

Are you struggling with databinding an enum property to a ComboBox in WPF? 🤔 Don't worry, I've got you covered! In this blog post, I'll walk you through the common issues you might encounter and provide easy solutions to make your ComboBox work in mode TwoWay. Let's dive in and find out the secret! 💪

💡 The Challenge: Databinding an Enum Property to a ComboBox

Let's start with the code snippet you provided as an example:

public enum ExampleEnum { FooBar, BarFoo }

public class ExampleClass : INotifyPropertyChanged
{
    private ExampleEnum example;

    public ExampleEnum ExampleProperty 
    { 
        get { return example; } 
        set { /* set and notify */; } 
    }
}

The goal is to databind the ExampleProperty enum to a ComboBox, displaying the options "FooBar" and "BarFoo" and allowing TwoWay binding. But how can we achieve that? 🤷

🔑 The Solution: Databinding the Enum Property

To populate the ComboBox with the right values and enable databinding, we can follow these steps:

Step 1️⃣: Retrieve the Enum values as a list of strings using an ObjectDataProvider and the static Enum.GetValues method. Add the following code within the <Window.Resources> section:

<Window.Resources>
    <ObjectDataProvider MethodName="GetValues"
                        ObjectType="{x:Type sys:Enum}"
                        x:Key="ExampleEnumValues">
        <ObjectDataProvider.MethodParameters>
            <x:Type TypeName="ExampleEnum" />
        </ObjectDataProvider.MethodParameters>
    </ObjectDataProvider>
</Window.Resources>

Step 2️⃣: Use the ExampleEnumValues as the ItemsSource for your ComboBox. Update your ComboBox definition like this:

<ComboBox ItemsSource="{Binding Source={StaticResource ExampleEnumValues}}"
          SelectedItem="{Binding Path=ExampleProperty}" />

That's it! Now your ComboBox should be populated with "FooBar" and "BarFoo", and the TwoWay binding should work as expected. 🥳

🌍 Bonus Tip: Internationalization (i18n)

If you want to add internationalization support to your ComboBox, you can utilize resource files to store different language values. But don't worry, we won't dive deep into it now. It's a topic for another blog post! 😉
