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?

Here is the code I tried:

window2.show(); 

Answer 1

Write your code in window1.

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

Answer 2

When you have created a new WPF application you should have a .xaml file and a .cs file. These represent your main window. Create an additional .xaml file and .cs file to represent your sub window.

MainWindow.xaml

<Window x:Class="WpfApplication2.MainWindow"     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     Title="MainWindow" Height="350" Width="525">     <Grid>         <Button Content="Open Window" Click="ButtonClicked" Height="25" HorizontalAlignment="Left" Margin="379,264,0,0" Name="button1" VerticalAlignment="Top" Width="100" />     </Grid> </Window> 

MainWindow.xaml.cs

public partial class MainWindow : Window {     public MainWindow()     {         InitializeComponent();     }      private void ButtonClicked(object sender, RoutedEventArgs e)     {         SubWindow subWindow = new SubWindow();         subWindow.Show();     } } 

Then add whatever additional code you need to these classes:

SubWindow.xaml SubWindow.xaml.cs
