c# - UWP - How to prevent InputPane from showing and hiding automatically -

i want manually control behavior of inputpane prevent showing or hiding automatically.

in page put image top, want inputpane show user navigate page , keep showing until he/she clicks on specified button , prevent hiding if user clicks anywhere else in page.

also want inputpane remain hidden if user clicks on textbox.

i know there tryshow() , tryhide(), can't revent auto showing , hiding.

the easy way control controlling focus of textbox. if set istabstop on textbox false - won't take focus , sip won't show up. if has focus - you'll need move out. if want display sip - focus textbox. note performance reasons , prevent user confusion - might make sense use textblock instead of textbox when control should not editable.
