Question

I want add the object 1 + object inside my Button clicked 

How do I go about it  

CODE IN XAML

<TextBox x:Name="object1" HorizontalAlignment="Left" Height="62" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="106" Margin="56,63,0,0" FontSize="16" BorderThickness="3"/>

<TextBox x:Name="object2" HorizontalAlignment="Left" Height="62" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="106" Margin="303,63,0,0" FontSize="16" BorderThickness="3"/>

<TextBox x:Name="Screen" HorizontalAlignment="Left" Height="62" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="166" Margin="155,225,0,0" FontSize="16" BorderThickness="3"/>

<Button Content="=" HorizontalAlignment="Left" VerticalAlignment="Top" Width="86" Height="43" Margin="193,146,0,0" Click="Button_Click"/>

 

CODE IN XAML.CS

private void Button_Click(object sender, RoutedEventArgs e)

{

Screen.Text = Screen.Text + "=";

}
