How can I ensure that only one KeyBinding command is executed when a keyboard shortcut is used?

Question

I have the following KeyBindings:

<KeyBinding Gesture="Ctrl+S" Command="Save" />
<KeyBinding Gesture="Ctrl+Shift+S" Command="SaveAs" />

When I press Ctrl+Shift+S to execute the SaveAs command, it works -- but directly afterwards, the Save command is also executed. Is this caused by my Gesture definitions?

Answer 1

You have to mark the RoutedEvent as Handled=true using the RoutedEventArgs parameter in your method that handles the save.
