Event triggers are fired when a particular event occurs. An event may be triggered by a user's action, such as a button click. Or it may be triggered by an automated process, such as the completion of a certain long-running action. We'll cover event triggers in .NET MAUI with the aid of the following project setup:

<?xml version = "1.0" encoding = "UTF-8" ?>
<Application xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:local="clr-namespace:EventTriggerDemo"
             x:Class="EventTriggerDemo.App">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Resources/Styles/Colors.xaml" />
                <ResourceDictionary Source="Resources/Styles/Styles.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>
