WPF ToggleButton and DelegateCommand

Is there a way to determine if a ToggleButton is Checked/Unchecked via DelegateCommands?

TIA, mike

XAML code below. I'm using ItemsControl and binding to a collection. I'm basically wanting a way to get the toggle status of each button when it's clicked.

<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}" />
            &开发者_运维技巧lt;/DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>
</ScrollViewer>

A simpler solution would be to bind the IsChecked property to a property of your ViewModel. That way you just have to check the property value...

Could you specify the CommandParameter declaratively in the XAML and use an element binding to populate the value with the current value of the toggle?
