How to highlight a button when it is pressed in WPF xaml

I have two button styles in Styles.xaml file like MyStyleButton and MyStyleButtonClick.

I applied MyStyleButton to the existing button like below

<Button Name="btnAllOrders" Content="All Orders Status" Click="btnAllOrders_Click" Height="50" Width="150" Style="{StaticResource MyStyleButton}" Margin="5" />
<Button Name="btnTakeOut" Content="Take Out" Click="btnOtherOrders_Click" Height="50" Width="150" Style="{StaticResource MyStyleButton}" Margin="5"/>

When Button is pressed I would like to apply "MyStyleButtonClick" in xaml page by using Triggers in order to show differentiation between those buttons.
