ScrollPattern.VerticalScrollPercentProperty Field

Identifies the VerticalScrollPercent property.

Namespace:  System.Windows.Automation
Assembly:  UIAutomationClient (in UIAutomationClient.dll)

public static readonly AutomationProperty VerticalScrollPercentProperty

This identifier is used by UI Automation client applications. UI Automation providers should use the equivalent field in ScrollPatternIdentifiers.

In the following example, a root element is passed to a function that returns the current 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;
}
