How do I open a second window from the first window in WPF?

Question

I am new to WPF. I have two windows, such as window1 and window2. I have one button in window1. If I click that button, the window2 has to open. What should I do for that?

Answer 1

In WPF we have a couple of options by using the Show() and ShowDialog() methods.

Well, if you want to close the opened window when a new window gets open then you can use the Show() method:

Window1 win1 = new Window1();
win1.Show();
win1.Close();

ShowDialog() also opens a window, but in this case you can not close your previously opened window.

Answer 2

You will need to create an instance of a new window like so.

var window2 = new Window2();

Once you have the instance you can use the Show() or ShowDialog() method depending on what you want to do.

window2.Show();

or

var result = window2.ShowDialog();

ShowDialog() will return a Nullable<bool> if you need that.

Answer 3

Assuming the second window is defined as public partial class Window2 : Window, you can do it by:

Window2 win2 = new Window2();
win2.Show();

Answer 4

Write your code in window1.

private void Button_Click(object sender, RoutedEventArgs e)
{
    window2 win2 = new window2();
    win2.Show();
}

Answer 5

You can use this code:

private void OnClickNavigate(object sender, RoutedEventArgs e)
{
    NavigatedWindow navigatesWindow = new NavigatedWindow();
    navigatesWindow.ShowDialog();
}

Answer 6

private void button1_Click(object sender, RoutedEventArgs e)
{
    window2 win2 = new window2();
    win2.Show();
}
