The touchscreen keyboard is provided by the Windows IoT operating system and needs to be enabled.

Open the web interface based “Windows Device Portal” as above and select: Device Settings > On-screen Keyboard > Set the checkbox to ticked

Make Keyboard appear

Give text box focus
Another method (won’t always work but can be useful sometimes)

Using a hidden TextBox

You can’t set a text box to not visible and have it still take focus / text entry, but you can achieve the same thing by setting its opacity to 0:

MyTextBox.Opacity = 0;

Stopping keyboard appearing

The TextBox class has PreventKeyboardDisplayOnProgrammaticFocus property
