Public Shared ReadOnly HorizontalScrollPercentProperty As AutomationProperty 

フィールド値

次の例では、ルート要素が、コンテンツ領域内の表示可能な領域の現在の水平方向および垂直方向のスクロール率を返す関数に渡されます。In the following example, a root element is passed to a function that returns the current horizontal and vertical scroll percentages of the viewable region within the content area.

///--------------------------------------------------------------------
/// <summary>
/// Obtains the current scroll positions of the viewable region 
/// within the content area.
/// </summary>
/// <param name="targetControl">
/// The automation element of interest.
/// </param>
/// <returns>
/// The horizontal and vertical scroll percentages.
/// </returns>
///--------------------------------------------------------------------
private double[] GetScrollPercentages(AutomationElement targetControl)
{
    if (targetControl == null)
    {
        throw new ArgumentNullException(
            "AutomationElement argument cannot be null.");
    }

    double[] percentage = new double[2];

    percentage[0] =
        (double)targetControl.GetCurrentPropertyValue(
        ScrollPattern.HorizontalScrollPercentProperty);

    percentage[1] =
         (double)targetControl.GetCurrentPropertyValue(
         ScrollPattern.VerticalScrollPercentProperty);

    return percentage;
}
