DynamicResourceExtension Class

Implements a markup extension that supports dynamic resource references made from XAML.

Inheritance Hierarchy

System..::.Object
System.Windows.Markup..::.MarkupExtension
System.Windows..::.DynamicResourceExtension

Namespace: System.Windows
Assembly: PresentationFramework (in PresentationFramework.dll)
XMLNS for XAML: http://schemas.microsoft.com/winfx/2006/xaml/presentation, http://schemas.microsoft.com/netfx/2007/xaml/presentation

Syntax

Visual Basic

<MarkupExtensionReturnTypeAttribute(GetType(Object))> _
<TypeConverterAttribute(GetType(DynamicResourceExtensionConverter))> _
Public Class DynamicResourceExtension _
    Inherits MarkupExtension

[MarkupExtensionReturnTypeAttribute(typeof(Object))]
[TypeConverterAttribute(typeof(DynamicResourceExtensionConverter))]
public class DynamicResourceExtension : MarkupExtension

Visual C++

[MarkupExtensionReturnTypeAttribute(typeof(Object))]
[TypeConverterAttribute(typeof(DynamicResourceExtensionConverter))]
public ref class DynamicResourceExtension : public MarkupExtension

[<MarkupExtensionReturnTypeAttribute(typeof(Object))>]
[<TypeConverterAttribute(typeof(DynamicResourceExtensionConverter))>]
type DynamicResourceExtension =  
    class
        inherit MarkupExtension
    end

XAML

For XAML information, see DynamicResource Markup Extension.

The DynamicResourceExtension type exposes the following members.

Constructors

	Name	Description
	DynamicResourceExtension()()()	Initializes a new instance of the DynamicResourceExtension class.
	DynamicResourceExtension(Object)	Initializes a new instance of the DynamicResourceExtension class, with the provided initial key.

Top

Properties

	Name	Description
	ResourceKey	Gets or sets the key specified by this dynamic resource reference. The key is used to lookup a resource in resource dictionaries, by means of an intermediate expression.

Methods

	Name	Description
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (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.)
	ProvideValue	Returns an object that should be set on the property where this extension is applied. For DynamicResourceExtension, this is the object found in a resource dictionary in the current parent chain that is keyed by the ResourceKey. (Overrides MarkupExtension..::.ProvideValue(IServiceProvider).)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

Dynamic resource references are necessary when referencing content that might change at run-time. The reasons for the content change might be application-initiated or might be external. One example is if you are including styles that rely on system resources that report user-configured preferences, such as themes, font settings and so on.

This class is a markup extension implementation. Markup extension classes in WPF exist mainly to provide infrastructure support for some aspect of the WPF XAML processor implementation, and the members exposed by the markup extension classes are not typically called from directly user code. This class particularly supports the DynamicResource Markup Extension usage from XAML. For more information about dynamic resource references, see DynamicResource Markup Extension.
