Blocking sending events from child to parent

I have very short contact with the C# and WPF, although most of the stuff I could find over the Internet. However, I cannot find anything (or don't know how to request google to find it) about blocking sending events to the parent.

I've got an Image inside ScrollViewer. My point is to create zooming option for the image by using Ctrl + mouse wheel, but obviously the scrollbars of the ScrollViewer are moving while I am moving mouse wheel (the mouse wheel method is defined within the Image). Is there any possibility to block event sent from child to parent when Ctrl is down?

In your handler for the Image, you should set the event's Handled property to true when Ctrl is pressed. This will prevent the ScrollViewer from handling the mouse wheel event.

See http://msdn.microsoft.com/en-us/library/ms742806.aspx for more information, especially the section entitled "The Concept of Handled."
