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.
1. <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">
2. <Grid>
3. <Button x:Name="button" Content="Button" HorizontalAlignment="Left" Margin="273,3,0,0" Grid.Row="3" VerticalAlignment="Top" Width="75" Height="17">
5. </Button> </Grid>
6. </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”.
1. <x:Code>
2. <![CDATA[
4. void Clicked(object sender, RoutedEventArgs e)
5. {
6. MessageBox.Show("Hello World");
7. }
8. ]]>
9. </x:Code>

The final status will be something like mentioned below.
1. <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">
2. <Grid>
3. <Button x:Name="button" Content="Button" HorizontalAlignment="Left" Margin="273,3,0,0" Grid.Row="3" VerticalAlignment="Top" Width="75" Height="17" Click="Clicked">
5. <x:Code>
6. <![CDATA[
7. void Clicked(object sender, RoutedEventArgs e)
8. {
9. MessageBox.Show("Hello World");
10. }
11. ]]>
12. </x:Code>
13. </Button> </Grid>
14. </Window>

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