FIX: GetValue function is called multiple times on each DataBinding event in Windows Embedded Compact 7


Assume that you have a Microsoft Silverlight for Windows Embedded (SWE) application that runs on a Windows Embedded Compact 7-based device. The GetValue function is called multiple times on each DataBinding or PropertyChanged event. This issue could lead to a performance issue on the application.

The kind of processor that each file applies to is visible in the name of each file in the "File information" section.


For the same binding property name, on each DataBinding event, add a cache in order to save the last property name, then at the second time, system will not call GetValue until the third time.
