AutomationElement.AutomationIdProperty Field

Identifies the AutomationId property, which is used to identify elements.

Namespace: System.Windows.Automation
Assembly: UIAutomationClient (in uiautomationclient.dll)

public static readonly AutomationProperty AutomationIdProperty
public static final AutomationProperty AutomationIdProperty
public static final var AutomationIdProperty : AutomationProperty
Not applicable.

This identifier is used by UI Automation client applications. UI Automation providers should use the equivalent identifier in AutomationElementIdentifiers.

This property can also be retrieved from the Current or Cached properties.

Return values of the property are of type String. The default value for the property is an empty string.

The AutomationIdProperty of an element is always the same in any instance of the application on any machine, regardless of the local language. If the property is supported by the element, the value is unique among sibling elements but not necessarily unique on the desktop. For example, multiple instances of an application, or multiple folder views in Microsoft Windows Explorer, may contain elements with the same AutomationIdProperty, such as "SystemMenuBar".

Instances of user interface (UI) elements are uniquely identified on the desktop by their RuntimeIdProperty properties.

NoteNote:

AutomationIdProperty is supported by all UI Automation elements in the control view except top-level application windows, UI Automation elements derived from Windows Presentation Foundation (WPF) controls that do not have an ID or x:Uid, and UI Automation elements derived from Win32 controls that do not have a control ID.

The following example retrieves the current value of the property. The default value is returned if the element does not provide one.

string autoId =
    autoElement.GetCurrentPropertyValue(AutomationElement.AutomationIdProperty) as string;

The following example retrieves the current value of the property, but specifies that if the element itself does not provide a value for the property, NotSupported is to be returned instead of a default value.

string autoIdString;
object autoIdNoDefault =
    autoElement.GetCurrentPropertyValue(AutomationElement.AutomationIdProperty, true);
if (autoIdNoDefault == AutomationElement.NotSupported)
{
    // TODO Handle the case where you do not wish to proceed using the default value.
}
else
{
    autoIdString = autoIdNoDefault as string;
}
