AutomationElement.LabeledByProperty Field

Identifies the LabeledBy property, which identifies the label associated with a control.

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

public static readonly AutomationProperty LabeledByProperty

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 AutomationElement. The default value for the property is null.

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

AutomationElement labeler =
    autoElement.GetCurrentPropertyValue(AutomationElement.LabeledByProperty) as AutomationElement;

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.

AutomationElement labeler1;
object labelerNoDefault =
    autoElement.GetCurrentPropertyValue(AutomationElement.LabeledByProperty, true);
if (labelerNoDefault == AutomationElement.NotSupported)
{
    // TODO Handle the case where you do not wish to proceed using the default value.
}
else
{
    labeler1 = labelerNoDefault as AutomationElement;
}
