Setter Class


Represents a setter that applies a property value.

public class Setter : System.Windows.SetterBase, System.ComponentModel.ISupportInitialize


The following example defines a Style that will be applied to every TextBlock element. This Style applies values to several TextBlock properties with the use of Setters.

<Style TargetType="{x:Type TextBlock}">
  <Setter Property="FontFamily" Value="Segoe Black" />
  <Setter Property="HorizontalAlignment" Value="Center" />
  <Setter Property="FontSize" Value="12pt" />
  <Setter Property="Foreground" Value="#777777" />

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">
    <Trigger Property="IsPressed" Value="true">
        <Setter Property = "Foreground" Value="Green"/>


Styles and the different types of triggers (classes that inherit from TriggerBase) use Setters to apply property values.

Note that you must specify both the Property and Value properties on a Setter for the setter to be meaningful. If one or both properties are not set, an exception will be thrown.
