c# - Why is my text box contained in a FlipView obscured by the soft keyboard when it pops up? -

please consider following xaml:

in it, have flipview operates in horizontal mode. content want display in flipview large - that's why added scrollviewer flipviewitem template user can scroll vertically (please note flipview template uses horizontal scrollviewer internally).

the content displayed flipview contains input controls text boxes , obviously, soft keyboard shown when user taps text box (so gets focused).

here actual question: why text box not translated remaining view port not obscured soft keyboard (see images)

obviously, has flipview because when display example view in scrollviewer (or no scrollviewer @ all), text box translated correctly when soft keyboard pops up.

i have tried following steps:

1. i tried enable vertical scrolling on scrollviewer in flipview's template - doesn't work because flipview seems overwrite corresponding values in onapplytemplate (or something) - verticalscrollmode disabled when orientation on flipview' virtualizingstackpanel set horizontal.
2. as mentioned above, tried display exact same view within scrollviewer (which worked fine) or without scrollviewer (which worked fine).
3. i check scrollviewer.bringintoviewonfocuschanged doesn't change (and besides, property has default value set true).

is there way can circumvent problem? thank in advance!

i'm not sure offhand why textboxes aren't translating up, can work around problem handling inputpane yourself.

subscribe inputpane.showing , hiding events. when fire animate flipview's rendertransform translate out of way of inputpane's occludedrect , set ensuredfocusedelementinview true mark app has handled , windows doesn't need again.

the responding appearance of on-screen keyboard sample demonstrates basics.
