創建一個視圖模型,爲您管理和公開設置。使用其他屬性來提供當前選定的設置:
public class CameraSettings
{
public string Title { get; set; }
public bool Grayscale { get; set; }
}
public class CameraViewModel : INotifyPropertyChanged
{
private CameraSettings _SelectedSettings;
private List<CameraSettings> _Settings;
public event PropertyChangedEventHandler PropertyChanged;
public IEnumerable<CameraSettings> Settings
{
get { return _Settings; }
}
public CameraSettings SelectedSettings
{
get { return _SelectedSettings; }
set
{
if (_SelectedSettings != value)
{
_SelectedSettings = value;
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs("SelectedSettings"));
}
}
}
}
public CameraViewModel()
{
_Settings = new List<CameraSettings>()
{
{ new CameraSettings() { Title = "BlackWhite", Grayscale = true } },
{ new CameraSettings() { Title = "TrueColor", Grayscale = false } }
};
}
}
然後,您可以將視圖綁定到此視圖模型。示例視圖:
<Window.DataContext>
<local:CameraViewModel />
</Window.DataContext>
<StackPanel>
<ComboBox ItemsSource="{Binding Settings}" SelectedItem="{Binding SelectedSettings, Mode=TwoWay}">
<ComboBox.ItemTemplate>
<DataTemplate>
<Label Content="{Binding Title}" />
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
<TextBlock Text="{Binding SelectedSettings.Grayscale}" />
</StackPanel>
發佈您當前的代碼和XAML。 –
