问题 Let me explain my question by an Image I have MVVM structure in My project. I have two textblocks, Textblock 1 and textblock 2 . Now I want textblock2's Text same as Textblock1's Text, whenever Textblock1's Text changed. but I should be able to set Textblock2's Text different from Textblock1's . So I am setting Oneway binding of Textblock1's Text Property. How Can I get the Text property of Textblock2's In MVVM. If I create a property for Textblock2's Text property, I wont be able to bind
