WPF Keyboard Modifier on MouseBinding

I'm working with the MVVM pattern in WPF (a bit new to both).

I'd like to set up an InputBinding on a CheckBox that corresponds to a Control + Click event, but do not see a Modifiers property on the MouseBinding element. This is what I'd like to achieve (fictitious code, obviously- Modifiers doesn't exist):

<CheckBox>
     <CheckBox.InputBindings>
           <MouseBinding MouseAction="LeftClick" 
                         Command="{Binding CheckboxControlClickCommand}"
                         Modifiers="Control" />
     </CheckBox.InputBindings>
</Chec开发者_运维百科kBox>

Any ideas on how to accomplish this without using events?

Thanks!


Use it with keybinding too!


An old question but looks like the MouseBinding now provides a Gesture attribute just for this..

<CheckBox>
     <CheckBox.InputBindings>
           <MouseBinding Gesture="CTRL+LeftClick" 
                         Command="{Binding CheckboxControlClickCommand}"/>
     </CheckBox.InputBindings>
</CheckBox>


I ended up using Keyboard.Modifiers in the Execute() context of the ICommand, which seemed to work just fine.

if (Keyboard.Modifiers != ModifierKeys.Control) return;
    ...


I think a behavior would do the trick. You can take a look at this link.
