Field Value

Examples

In the following example, a root element is passed to a function that returns a collection of AutomationElements 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="targetApp">
/// 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 targetApp)
{
    if (targetApp == null)
    {
        throw new ArgumentException("Root element cannot be null.");
    }

    PropertyCondition conditionIsReadOnly =
        new PropertyCondition(
        RangeValuePattern.IsReadOnlyProperty, false);

    return targetApp.FindAll(
        TreeScope.Descendants, conditionIsReadOnly);
}
