Definition

Gets or sets an arbitrary object value that can be used to store custom information about this element.

public:
 property System::Object ^ Tag { System::Object ^ get(); void set(System::Object ^ value); };
[System.Windows.Localizability(System.Windows.LocalizationCategory.NeverLocalize)]
public object Tag { get; set; }
member this.Tag : obj with get, set
Public Property Tag As Object
Property Value

The intended value. This property has no default value.

Remarks

This property is analogous to Tag properties in other Microsoft programming models, such as Visual Basic for Applications or Windows Forms. Tag is intended to provide a pre-existing property location where you can store some basic custom information about any FrameworkElement without requiring you to subclass an element.

Because this property takes an object, you need to use the property element usage in order to set the Tag property in XAML to anything other than an object with a known and built-in type converter, such as a string. Objects used in this manner are typically not within the standard WPF namespaces and therefore may require namespace mapping to the external namespace in order to be introduced as XAML elements. For details, see XAML Namespaces and Namespace Mapping for WPF XAML and XAML and Custom Classes for WPF.
