C# Code In WPF XAML File

Here, we will learn how to write C# code in WPF XAML.

Step 1 Create WPF Window

• Create new WPF window in WPF application.
• Add a Button in the created window.
  

  <Window x:Class="DropBoxIntegration.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:local="clr-namespace:DropBoxIntegration" mc:Ignorable="d" Title="MainWindow" Height="321" Width="1024" MinHeight="300" MinWidth="600">
      <Grid>
          <Button x:Name="button" Content="Button" HorizontalAlignment="Left" Margin="273,3,0,0" Grid.Row="3" VerticalAlignment="Top" Width="75" Height="17">
  
  </Button> </Grid>
  </Window>

Step 2 Messagebox popup on button click.

• Add the below mentioned code as it is inside <button> tag.
• Bind the Buttonclick event to the below event “Clicked”.
  

  <x:Code>
      <![CDATA[
  
  void Clicked(object sender, RoutedEventArgs e)
  {
      MessageBox.Show("Hello World");
  }
  ]]>
  </x:Code>

• The final status will be something like mentioned below.
  

  <Window x:Class="DropBoxIntegration.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:local="clr-namespace:DropBoxIntegration" mc:Ignorable="d" Title="MainWindow" Height="321" Width="1024" MinHeight="300" MinWidth="600">
      <Grid>
          <Button x:Name="button" Content="Button" HorizontalAlignment="Left" Margin="273,3,0,0" Grid.Row="3" VerticalAlignment="Top" Width="75" Height="17" Click="Clicked">
  
  <x:Code>
  <![CDATA[
     void Clicked(object sender, RoutedEventArgs e)
     {
        MessageBox.Show("Hello World");
     }
  ]]>
  </x:Code>
     </Button> </Grid>
  </Window>

That’s it. We are done. Try it yourself and see the result.
