How to programmatically hide the keyboard
c#, windows-phone
Solution
Just set focus to the main page:
this.Focus();
this will focus a control that doesn't use the keyboard and thus hide the keyboard. Unfortunately there is no API to the keyboard to hide it.
Problem
I have a textbox with a button inside (Telerik's RadTextBox with an Action configured). When the user presses the Action, a progress bas is displayed, the screen goes dark, and some magic happens. My problem is that since the action doesn't result in the textbox losing focus, the on-screen keyboard is not hidden, and keeps covering half the screen. I would like to programmatically hide the on-screen keyboard, but don't know how.
