Observe which window sent a Close() event

I have a short questions and even after a while of searching through the web I have not found the answer. I have two windows in a WPF application. One window should just be hidden when the user closes it. When the main window is closed the complete application shall close.

I used 

    private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
    {
        e.Cancel = true;
        Hide();
    }

inside the class of the second window and hoped it would just catch its Close() event but unfortunately it catches all Close() events.

How can I separate between the windows to handle the events independently?

Regards Larimow

Use the sender parameter, that's what it's there for:

window1.Closing += Window_Closing;
window2.Closing += Window_Closing;

private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
    var w = (Window)sender;

    // Simple ref test to illustrate, but you can use anything else you want instead
    if (w == window1) {
        e.Cancel = true;
        w.Hide();
    }
}
