How to get value from one window to another?

Question

WPF

There are 2 windows: FirstWindow and SecondWindow
SecondWindow is called from FirstWindow by clicking on MenuItem. Also in FirstWindow there is a TextBlock whose value should be available from SecondWindow after it is opened. I hope I explained clearly.

How can I do that?

Answer 1

The simplest, in SecondWindow, pass a link to the textblock to the sw constructor and store it in a private field
