WPF ToggleButton and DelegateCommand

Is there a way to determine if ToggleButton checked or not checked using DelegateCommand s?

TIA, microphone

The XAML code is below. I use ItemsControl and bind to the collection. I basically want to get the switching status of each button when pressed.

 <ScrollViewer VerticalScrollBarVisibility="Auto"> <ItemsControl ItemsSource="{Binding Modifiers, Mode=TwoWay}"> <ItemsControl.Template> <ControlTemplate> <ScrollViewer ScrollViewer.VerticalScrollBarVisibility="Auto"> <WrapPanel Margin="10" Width="{TemplateBinding Width}" Height="{TemplateBinding Height}" FlowDirection="LeftToRight" IsItemsHost="true"> </WrapPanel> </ScrollViewer> </ControlTemplate> </ItemsControl.Template> <ItemsControl.ItemTemplate> <DataTemplate> <ToggleButton FontSize="18" Opacity="0.8" Command="{Binding DataContext.ModifierToggleCommand, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Views:ModifiersView}}}" CommandParameter="{Binding}" Height="80" Width="200" Margin="5" Content="{Binding Path=ModifierName}" /> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> </ScrollViewer>

A simpler solution would be to bind the IsChecked property to the property of your ViewModel. So you just need to check the value of the property ...

Is it possible to describe CommandParameter declaratively in XAML and use element binding to populate the value with the current value of the switch?
