We have a .NET 5 WPF touchscreen application that needs to accept passwords to run an override authorization. We are currently using a System.Windows.Controls.PasswordBox control but the control does not start the TabTip (or any) on screen keyboard when it receives focus. I tried calling TabTip directly but that throws an exception that elevation is required. Is there a recommended way to integrate the PasswordBox with touch screen applications? Thanks, Brian

Could you show me your code snippet of calling TabTip? What is your exception? What is your system version? Is the version higher than 10.0.14393? -

2021-05-06T16:40:21.153+00:00 We finally traced it down to an issue with replacing the Explorer shell in a Kiosk mode setup. If I had tablet mode enabled but never interacted with the Folder Explorer, then it would not run in tablet mode. If I used a developer option to start the Folder Explorer then it started working. The solution was to turn on the feature to always enable the on screen keyboard when no physical keyboard was attached. That caused it to work in all modes and is really what we wanted anyhow.
