Today due to numerous requests (technically one request from one person ), I updated my CodePlex project for calendar control for Windows Phone 7 – http://wpcontrols.codeplex.com/.
I added gesture support to the project. You can now swipe (flick) from side to side to increment or decrement month, and swipe top to bottom and back to increment or decrement year.
I thought it was a very good enhancement idea that feels very natural to me to support on Windows phone. I used XNA libraries to enable this support, and it only required a few lines of code. To enable support you will need to set property on the calendar control – EnableGestures – to true.
Please let me know if you have any feedback.
