RuntimeNamePropertyAttribute Class


Represents a type-level attribute that reports which property of the type maps to the XAML x:Name attribute.

public ref class RuntimeNamePropertyAttribute sealed : Attribute
public sealed class RuntimeNamePropertyAttribute : Attribute
type RuntimeNamePropertyAttribute = class
    inherit Attribute
Public NotInheritable Class RuntimeNamePropertyAttribute
Inherits Attribute


The property that is specified in the RuntimeNamePropertyAttribute must be of type String and must be read/write.

Frameworks might attribute a certain property of one its architectural base elements to be the XAML name equivalent. This is done so that the concept of a XAML name in a XAML namescope set at XAML load time is available to a framework's programming model at run time.

A XAML name value must use the XamlName Grammar.

In previous versions of the .NET Framework, this class existed in the WPF-specific assembly WindowsBase. In .NET Framework 4, RuntimeNamePropertyAttribute is in the System.Xaml assembly. For more information, see Types Migrated from WPF to System.Xaml.

WPF Usage Notes

An example of an existing class in Windows Presentation Foundation (WPF) where the RuntimeNamePropertyAttribute is applied is FrameworkElement. The Name property on FrameworkElement is attributed with RuntimeNamePropertyAttribute, which results in any FrameworkElement derived class also using Name as its run-time name property.

In general, you do not typically need to apply this attribute in WPF unless you are implementing a new or FrameworkElement-parallel framework-level class. x:Name should take precedence over the run-time name property if both exist as attributes on an element, and a XAML processor implementation generally throws in this case.



Initializes a new instance of the RuntimeNamePropertyAttribute class.



Gets the name of the runtime name property that is specified by this RuntimeNamePropertyAttribute.


When implemented in a derived class, gets a unique identifier for this Attribute.

(Inherited from Attribute)



Returns a value that indicates whether this instance is equal to a specified object.

(Inherited from Attribute)

Returns the hash code for this instance.

(Inherited from Attribute)

Gets the Type of the current instance.

(Inherited from Object)

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.

(Inherited from Attribute)

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.

(Inherited from Attribute)

Creates a shallow copy of the current Object.

(Inherited from Object)

Returns a string that represents the current object.

Explicit Interface Implementations

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.

(Inherited from Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.

(Inherited from Attribute)

Retrieves the number of type information interfaces that an object provides (either 0 or 1).
