How do I open a second window from the first window in WPF?

Question

I am new to WPF. I have two windows, such as window1 and window2. I have one button in window1. If I click that button, the window2 has to open. What should I do for that?

Answer 1

You will need to create an instance of a new window like so.

var window2 = new Window2();

Once you have the instance you can use the Show() or ShowDialog() method depending on what you want to do.

window2.Show();

or

var result = window2.ShowDialog();

ShowDialog() will return a Nullable if you need that.
