AutomationElement listElement = elementCombo.FindFirst(TreeScope.Children, propCondition1);

Dim propCondition1 As New PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.List)
Dim listElement As AutomationElement = elementCombo.FindFirst(TreeScope.Children, propCondition1)

Remarques

Le paramètre property ne peut pas avoir la valeur BoundingRectangleProperty.

public:
 PropertyCondition(System::Windows::Automation::AutomationProperty ^ property, System::Object ^ value, System::Windows::Automation::PropertyConditionFlags flags);

public PropertyCondition (System.Windows.Automation.AutomationProperty property, object value, System.Windows.Automation.PropertyConditionFlags flags);

new System.Windows.Automation.PropertyCondition : System.Windows.Automation.AutomationProperty * obj * System.Windows.Automation.PropertyConditionFlags -> System.Windows.Automation.PropertyCondition

Exemples

L’exemple suivant utilise un PropertyCondition pour récupérer l’élément Microsoft UI Automation représentant la forme main d’une application. Le formulaire se trouve par une recherche qui ne respecte pas la casse pour son identificateur de chaîne.
