Esempio

Nell'esempio seguente viene ottenuto un GridPattern pattern di controllo da un elemento Automazione interfaccia utente.

/// <summary>
/// Obtains a GridPattern control pattern from an 
/// automation element.
/// </summary>
/// <param name="targetControl">
/// The automation element of interest.

/// <returns>
/// A GridPattern object.
/// </returns>
///--------------------------------------------------------------------
private GridPattern GetGridPattern(
    AutomationElement targetControl)
{
    GridPattern gridPattern = null;

    try
    {
        gridPattern =
            targetControl.GetCurrentPattern(
            GridPattern.Pattern)
            as GridPattern;
    }
    // Object doesn't support the 
    // GridPattern control pattern
    catch (InvalidOperationException)
    {
        return null;
    }

    return gridPattern;
}

Commenti

Questo identificatore viene usato da Automazione interfaccia utente applicazioni client. Automazione interfaccia utente provider devono usare il campo equivalente in GridPatternIdentifiers.

L'identificatore del modello viene passato a metodi quali GetCurrentPattern per recuperare il pattern di controllo di interesse dall'oggetto specificato AutomationElement.
