AutomationElement.IsEnabledProperty Field

Definition

Identifies the IsEnabled property, which specifies whether the user interface (UI) item referenced by the AutomationElement is enabled.

public: static initonly System::Windows::Automation::AutomationProperty ^ IsEnabledProperty;
public static readonly System.Windows.Automation.AutomationProperty IsEnabledProperty;
 staticval mutable IsEnabledProperty : System.Windows.Automation.AutomationProperty
Public Shared ReadOnly IsEnabledProperty As AutomationProperty 

Field Value

Examples

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

bool isControlEnabled = (bool)
   autoElement.GetCurrentPropertyValue(AutomationElement.IsEnabledProperty);
Dim isControlEnabled As Boolean = _
    CBool(autoElement.GetCurrentPropertyValue(AutomationElement.IsEnabledProperty))

Remarks

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 Boolean. The default value for the property is false.

When the enabled state of a control is false, it is assumed that child controls are also not enabled. You should not expect property-changed events from child elements when the state of the parent control changes.
