Triggers allow us to declare actions in XAML, which changes the appearance of the control when a specific condition is met for a particular property of the control.

We can add triggers at control-level, page-level, or application-level in the resource dictionary. Here are the four types of triggers available. These are:

Property Trigger: This trigger executes when the property of the control set a particular value.

Data Trigger: This trigger is similar to a property trigger, but it uses the data binding.

Event Trigger: This trigger occurs when an event occurs on the control.

Multi Trigger: This trigger allows us to set the conditions of multiple triggers before the action occurs.
