This example shows how to manipulate TEXT and TEXTBLOCK parts from code.
The very first we are going to do is register a callback to react to changes in the text of our parts:  
And we now move on to selection issues, first thing we do is make sure the user can select text:  
 We now unselect the entire text(set selection to none), and print the selected text:
