Two things I can't seem to figure out VS2017, wpf

First one is the onscreen touch keyboard - it always shows up on the bottom of the screen and that hides the textbox that made it appear in the first place. Is there a way to tell the keyboard where to appear (part of screen or coordinates?)
The second one is related - how to set inputscope on a datagrid column? I found it for the whole datagrid but I have a mix of numeric and regular text columns so I don't want to set it to only one by default. I'd rather use numeric for numeric and default for regular text. Any clues?

Oh and windows 10

Wasn;'t what I was expecting but it is good to know. Doesn't work on my Win10 Pro Lenovo netbook/tablet though.
