Question

I have a small problem, when I open a new window in WPF like so:

    private void button2_Click(object sender, RoutedEventArgs e)
    {
        var newWindow = new Main();
        newWindow.Show();

    }

If I try to use Application.Current.Shutdown(); at the end of it my entire application shuts down rather than just my first initial window. So my question would be is there a way to open a new window while closing the previous window safely?

Thanks 🙂

I’d do something like this:

//Somewhere in your class 
YourOtherForm otherForm = null;

//then, on the event handler
private void button2_Click(object sender, RoutedEventArgs e)  {
    if((otherForm.IsDisposed) || (null == otherForm)) {
         otherForm = new YourOtherForm();
         // or, this is an MDI or something
         // otherForm = new YourOtherForm(this);
         // assuming you have an extra constructor to pass the parent
    }
    otherForm.Show();
    this.Close(); // or this.Hide(); if it's the main form
}

Edit: I haven’t tested this code tho..
