Scrollviewer & Zoomout.. event handlers near the border..? (Read 2165 times)

	We have diagram embedded inside the scrollviewer. But when the user zooms out there is an area (outside nodes) which does not belong to the diagram though the background is colored the same. The eventual ctrl-mousewheel events do not even reach our diagram if the user tries to zoom back in while pointing near the border. If he points onto nodes, the zooming works. Pointing on sides near the scrollbars, no zooming happens. This is confusing for the user. Any way to solve it elegantly? cheers

	You can handle the ScrollViewer.MouseWheel event instead the diagram's one. That should let you detect the events in the margin area between the diagram and viewer too. I hope that helps, Stoyan
