I'm seeing very spotty/unresponsive behavior with the silverlight map control on Windows Phone 7 (Microsoft.Phone.Controls.Map). The map control doesn't seem to pick up a lot of my pinch gestures. Is anyone else seeing this? Is there a way a workaround?
Just as an experiment I hooked up custom gesture listeners to PinchStarted, PinchDelta and PinchCompleted. My event handlers are getting fired every time I pinch, but the Silverlight map control doesn't pick them "most" of the times.
PS. I'm using the most up to date SDK/Toolkits.
After talking to our Microsoft contact we have no answers for the pinch performance problems. The official side stepped our question but and recommend putting a +/- buttons on the map for zooming in and out of the Map. To show the +/- buttons use the ZoomBarVisible property.
