Style.Triggers Property

Definition

Gets a collection of TriggerBase objects that apply property values based on specified conditions.

public System.Windows.TriggerCollection Triggers { get; }
Property Value

A collection of TriggerBase objects. The default is an empty collection.

Examples

The following example shows a named Style available to Button controls. The Style defines a Trigger element that changes the Foreground property of a button when the IsPressed property is true.

<Style x:Key="Triggers" TargetType="Button">
    <Style.Triggers>
    <Trigger Property="IsPressed" Value="true">
        <Setter Property = "Foreground" Value="Green"/>
    </Trigger>
    </Style.Triggers>
</Style>

Remarks

The WPF styling and templating model enables you to specify triggers within your Style. Essentially, triggers are objects that enable you to apply changes when certain conditions (such as when a certain property value becomes true, or when an event occurs) are satisfied.
