Examples
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" />
</Style>
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
Styles and the different types of triggers (classes that inherit from TriggerBase) use Setters to apply property values.
You must specify both the Property and Value properties on a Setter for the setter to be meaningful. In .NET 8 and earlier versions, an exception is thrown if one or both properties aren't set.
Content Model: In .NET 9 and later versions, the content property for Setter is Value, and it's optional to specify Value as an attribute.
Constructors
Setter() |
Initializes a new instance of the Setter class. |
Setter(DependencyProperty, Object) |
Initializes a new instance of the Setter class with the specified property and value. |
Setter(DependencyProperty, Object, String) |
Initializes a new instance of the Setter class with the specified property, value, and target name. |
Properties
IsSealed |
Gets a value that indicates whether this object is in an immutable state. (Inherited from SetterBase) |
Property |
Gets or sets the property to which the Value will be applied. |
TargetName |
Gets or sets the name of the object this Setter is intended for. |
Value |
Gets or sets the value to apply to the property that is specified by this Setter. |
Methods
CheckSealed() |
Checks whether this object is read-only and cannot be changed. (Inherited from SetterBase) |
Equals(Object) |
Determines whether the specified object is equal to the current object. (Inherited from Object) |
GetHashCode() |
Serves as the default hash function. (Inherited from Object) |
GetType() |
Gets the Type of the current instance. (Inherited from Object) |
MemberwiseClone() |
Creates a shallow copy of the current Object. (Inherited from Object) |
ReceiveMarkupExtension(Object, XamlSetMarkupExtensionEventArgs) |
Handles cases where a markup extension provides a value for a property of Setter object. |
ReceiveTypeConverter(Object, XamlSetTypeConverterEventArgs) |
Handles cases where a type converter provides a value for a property of a Setter object. |
ToString() |
Returns a string that represents the current object. (Inherited from Object) |
Explicit Interface Implementations
ISupportInitialize.BeginInit() |
Signals the object that initialization is starting. |
ISupportInitialize.EndInit() |
Signals the object that initialization is complete. |
