How to Zoom Out with WP7 Map Control

Question

I have a silverlight WP7.5 appplication with a Bing Map control. If I double click on the Map, it will zoom in on that location. What is the equivalent Zoom Out with the Mouse?

Answer 1

I've ran into this issue before. I normally just add a simple button for zooming out when testing in the emulator. Alternatively you can follow this blog post for a more indepth solution: http://michaelsync.net/2010/04/06/step-by-step-tutorial-installing-multi-touch-simulator-for-silverlight-phone-7

It doesn't seem right that you can click to Zoom In, but that there is no equivalent, like ALT Click, to Zoom out.

Answer 3

There isn't one for the emulator. Thus the blog post that shows how to create better multitouch simulations.

Answer 4

I'm using the ZoomBarVisibility property of the map control. You could set it to Visible in debug and Collapsed in release. + and - buttons are displayed on the map.

I leave it Visible even in release...
