<object Property="DependencyProperty" .../>

Property Value

A DependencyProperty to which the Value will be applied. The default value is null.

Exception typeCondition


The Property property cannot be a null reference (Nothing in Visual Basic).


The specified Property property cannot be read-only.


If the specified Value is not valid for the type of the specified Property.

Note that you must specify both the Property and Value properties on a Setter or an exception will be thrown.

The following example defines a style that will be applied to every TextBlock element.

<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 style declaration that will affect the Background property of a Control. Note that property name in this example is qualified with the name of the class (Control) because the Style does not specify a TargetType.

<Style x:Key="Style1">
  <Setter Property="Control.Background" Value="Yellow"/>
