how to improve the performance of load thumbnail on surface? RRS feed

  • 问题

  • I make a WPF store app, make all my picture in picture library into a GridView, the screen will show many picture(nearly 30-50). It's profect in pc. But when install it to Surface, the proformance is too bad.when thumbnail is loading, the UI proformance is not very smooth.

    I try set uri to BitmapImage in converter or using GetThumbnailAsync to get IRandomAccessStream and SetSource to BitmapImage(not await), UI proformance is not smooth too.   Is the UI thread too weak to bear propertychanged event?

    I saw the Photos app of win8, It's very smooth in any time. But it has a large size database, maybe it save the thumbnail stream into database. OMD, do we have more common method?
