UidPropertyAttribute Class


Indicates the CLR property of a class that provides the x:Uid Directive value.

public ref class UidPropertyAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Class, AllowMultiple=false)]
public sealed class UidPropertyAttribute : Attribute
[<System.AttributeUsage(System.AttributeTargets.Class, AllowMultiple=false)>]
type UidPropertyAttribute = class
    inherit Attribute
Public NotInheritable Class UidPropertyAttribute
Inherits Attribute


The UidPropertyAttribute is a XAML language attribute that identifies element nodes in markup so that they can be uniquely identified. Although the model for x:Uid is potentially more general, one usage of unique identifiers for XAML elements is for localization tools, so that XAML language components that need localization can generate a companion localization source and then re-integrated with the original XAML. For more information on how x:Uid is used in WPF localization. see WPF Globalization and Localization Overview.

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