Remarks

Scenarios and techniques for System.Windows.Automation.AutomationProperties are described in detail in the topic Automation Properties for Accessibility Support in UI.

This class defines several attached properties. In Silverlight, all attached properties are backed by dependency properties. Attached properties are a XAML concept, whereas dependency properties are a concept implemented by Silverlight and also WPF. Thus the attached property system in Silverlight includes concepts that are related to XAML as well as to the general Silverlight dependency property concepts. In code, you can get or set the attached properties either using a dedicated accessor, or by using GetValue and SetValue.

For example, to set a value for AutomationProperties.AutomationId in code, you could either call SetAutomationId (the dedicated accessor), or call SetValue and pass the AutomationIdProperty identifier. For more information on attached properties in Silverlight, see Attached Properties Overview.
