c# - Flip View Data Binding and file permissions -

-



i learning basics of uwp , app making in windows 10. trying make flip view data pulled off folder. didn't display images, tried manually adding images so,

privateset_images.add(new bitmapimage(new uri("ms-appx:///assets/spot/1.png"))); privateset_images.add(new bitmapimage(new uri("ms-appx:///assets/spot/2.png")));  privateset_images.add(new bitmapimage(new uri("ms-appx:///assets/spot/jpg.jpg"))); privateset_images.add(new bitmapimage(new uri("ms-appx:///assets/spot/jpeg.jpeg"))); privateset_images.add(new bitmapimage(new uri("ms-appx:///assets/spot/jpg.png"))); privateset_images.add(new bitmapimage(new uri("ms-appx:///assets/spot/jpeg.png")));  privateset_images.add(new bitmapimage(new uri("f:\\test sp folder\\1.png"))); privateset_images.add(new bitmapimage(new uri("f:/test sp folder/1.png")));

all ms-appx assets read , displayed (so not file-type / file-extension problem). permissions folder, used folder picker access few files, there no permission issues (as described here). checked debugger, , files read properly, last 2 aren't displayed (which point same file, wanted make sure wasn't '/' or '\\' preventing them being displayed.)

xaml code:

<flipview x:name="flipviwe"  itemssource="{x:bind viewmodel.images}" visibility="visible">     <flipview.itemtemplate>     <datatemplate>         <image source="{binding}" stretch="fill"/>     </datatemplate>      </flipview.itemtemplate> </flipview>

i don't seem able solve solutions or similar questions bind collection itemssource, flipview not showing pictures , show image files directory in flipview missing? thank you.

the uwp apps not have permission access files on device. default, apps can access file system locations such application install directory or application data locations. more info, please see file access permissions.

"f:\test sp folder\1.png" location app can't directly access. while dealing files or folders in uwp, 1 important rule skip path: stick storagefile.

it recommend use folder​picker let user pick folder , add app's futureaccesslist or mostrecentlyusedlist, in way can reloaded later without requiring user go through picker. more information, please check: how track recently-used files , folders.
