How to open window from xaml without code-behind

Question

I have other-window.xaml file and trying to open this from window.xaml on button click. How did it without code-behind?

Answer 1

You could define the window as a non-shared resource and write an Interactivity TriggerAction that resolves the resource and calls Show on the window. That action can then be used in the combination with an Interactivity EventTrigger on Click.
