Windows Phone 8 Handle event when the map stops scrolling

Question

I am working on an application using map on WP8 and I have to know when does the map stop scrolling so I can send my asynchronous requests to the webservice to get my data.

The only event handler I found which could correspond is ViewChanged but the problem is that it is called while the map is still moving, and I only want to send requests to my server when the user stops scrolling where he wants.

Has anyone encountered this problem and found a solution to it ?

Thank you

It should be fired only when the map has stopped changing that's why you have two different events: ViewChanging and ViewChanged.

See Maps events on the MSDN:

Additionnaly, you can also use CenterChanged and ZoomLevelChanged that should be fired when the view has been updated.

• CenterChanged:

• ViewChanged:
