Question

I want to open window2.xaml from the window1.xaml window as an emergent (floating) window.
In winforms that was form2.show() , how do I do it in WPF for both WPF application and WPFbrowser application?
(I assume it’s different for WPF application and WPFbrowser application)

Answer 1

It is not much different in WPF than winforms. The method itself is still Show() for a WPF window.

Button btnClick = new Button();
btnClick.Click +=  btnClick_Click;

void btnClick_Click(object sender, RoutedEventArgs e)
    {
        window2 exampleWindow = new window2();
        exampleWindow.Show();
    }

You pick where you want to instantiate and show the window depending on how you want your program to operate.

Update:

In a WPF web app you have ChildWindows. If you create your own custom window which inherits ChildWindow it will call just like any other window in a WPF app. The method is once again.

exampleChildWindow.Show();
