AutomationElement.NotSupported Field

Indicates that a property is not supported.

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

public static readonly Object NotSupported

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

The following example retrieves the help text property for an AutomationElement, specifying that NotSupported should be returned if the control does not support that property.

// elementList is an AutomationElement.
object help = elementList.GetCurrentPropertyValue(AutomationElement.HelpTextProperty, true);
if (help == AutomationElement.NotSupported)
{
    help = "No help available";
}
string helpText = (string)help;
