WPF Binding ComboBox enum item

Yes — this is fully supported in WPF using two-way data binding.
You bind:

• ComboBox ? Enum

• Slider + TextBox ? selected object property

• All update automatically

1. Enum

public enum VolumeLevel
{
    Low,
    Medium,
    High
}

2. ViewModel (INotifyPropertyChanged)

public class SettingsViewModel : INotifyPropertyChanged
{
    private VolumeLevel _selectedLevel;
    private double _volume;

    public Array VolumeLevels => Enum.GetValues(typeof(VolumeLevel));

    public VolumeLevel SelectedLevel
    {
        get => _selectedLevel;
        set
        {
            _selectedLevel = value;
            Volume = value switch
            {
                VolumeLevel.Low => 20,
                VolumeLevel.Medium => 50,
                VolumeLevel.High => 80,
                _ => Volume
            };
            OnPropertyChanged(nameof(SelectedLevel));
        }
    }

    public double Volume
    {
        get => _volume;
        set
        {
            _volume = value;
            OnPropertyChanged(nameof(Volume));
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;
    void OnPropertyChanged(string name) =>
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(name));
}

3. XAML (Two-way binding)

What happens automatically

Selecting ComboBox item updates Slider & Text
Moving Slider updates bound object
TextBox editing updates Slider
All synced via TwoWay binding

Note

• Use INotifyPropertyChanged

• Use TwoWay binding

• No code-behind needed

• This is MVVM-correct

Summary

• ComboBox binds to enum

• Slider & Text bind to object property

• Changes propagate both directions automatically

This is the cleanest and correct WPF solution.
