Need to know when a non-modal window has closed

I have opened childwindow from parentWindow (non-modal) - what's the best approach to achieving a 'wait' so that parentWindow will know when childWindow has closed? For a couple of reasons I cannot use showDialog(). I have tried a while loop (testing the childWindow's visibility property) but it just breaks (no exception - but just doesn't open childWindow). Is it a case of multi-threading??

You could use events so the parent window is notified when the child window closes. For instance, there is the Closed event.

Window childWindow = new ....
childWindow.Closed += (sender, e) =>
    {
        // Put logic here
        // Will be called after the child window is closed
    };
childWindow.Show();

I think you can use this:

    public ShowChild()
    {
        childWindow child = new childWindow();
        child.Closed += new EventHandler(child_Closed);
        child.Show();
    }

    void child_Closed(object sender, EventArgs e)
    {
        // Child window closed
    }
