Examples

/// Finds all automation elements that satisfy 
/// the specified condition(s).

/// <param name="targetControl">
/// The specific grid container of interest.
/// </param>
/// <returns>
/// A collection of automation elements satisfying 
/// the specified condition(s).
/// </returns>
///--------------------------------------------------------------------
private AutomationElementCollection FindAutomationElement(
    AutomationElement targetApp, AutomationElement targetControl)
{
    if (targetApp == null)
    {
        throw new ArgumentException("Root element cannot be null.");
    }

    PropertyCondition conditionSupportsGridItemPattern =
        new PropertyCondition(
        AutomationElement.IsGridItemPatternAvailableProperty, true);

    PropertyCondition conditionContainerGrid =
        new PropertyCondition(

        conditionContainerGrid);

    return targetApp.FindAll(
        TreeScope.Descendants, conditionGridItems);
