I have a pivot windows phone 7 app on which there is a bing map with 300 pushpins. When the user tries to pinch the map, the refresh time in my Lg optimus7 is really long and performances are poor.
Is there anything i can do to solve the problem or 300 pins are a number to avoid and i need to find another solution?
One of the design guidelines states that you shouldn’t use a Bing Map Control on a Pivot nor on a Panorama Control. This is due to the fact that both controls respond to touch and tend to interfere with each other. See: Map inside Panorama moves the panorama when panning map
So my solution was to move the map to a single page/form. Others have suggested (just google for those) to disable hittest on the map (making it read-only) but I do not like the messing with expected behavior.
300 pushpins might be a problem too but by (temporarily) moving the map to a separate form you will be able to find out what is slowing it down.
