AutomationElement の ToggleState。The ToggleState of the AutomationElement. 既定値は Indeterminate です。The default value is Indeterminate.

例

次の例では、ルート要素が、ルートの子孫であるオートメーション要素のコレクションを返す関数に渡され、一連のプロパティ条件を満たしています。In the following example, a root element is passed to a function that returns a collection of automation elements that are descendants of the root and satisfy a set of property conditions.

///--------------------------------------------------------------------
/// <summary>
/// Finds all automation elements that satisfy 
/// the specified condition(s).
/// </summary>
/// <param name="rootElement">
/// The automation element from which to start searching.
/// </param>
/// <returns>
/// A collection of automation elements satisfying 
/// the specified condition(s).
/// </returns>
///--------------------------------------------------------------------
private AutomationElementCollection FindAutomationElement(
    AutomationElement rootElement)
{
    if (rootElement == null)
    {
        throw new ArgumentException("Root element cannot be null.");
    }

    PropertyCondition conditionOn =
        new PropertyCondition(
        TogglePattern.ToggleStateProperty, ToggleState.On);

    PropertyCondition conditionIndeterminate =
        new PropertyCondition(
        TogglePattern.ToggleStateProperty, ToggleState.Indeterminate);

    // Use any combination of the preceding condtions to 
    // find the control(s) of interest
    OrCondition condition = new OrCondition(
        conditionOn,
        conditionIndeterminate);

    return rootElement.FindAll(TreeScope.Descendants, condition);
}
