ScrollPattern.VerticallyScrollableProperty Field

 

Identifies the VerticallyScrollable property.

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

public static readonly AutomationProperty VerticallyScrollableProperty

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 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 conditionSupportsScroll =
        new PropertyCondition(
        AutomationElement.IsScrollPatternAvailableProperty, true);

    PropertyCondition conditionHorizontallyScrollable =
        new PropertyCondition(
        ScrollPattern.HorizontallyScrollableProperty, true);

    PropertyCondition conditionVerticallyScrollable =
        new PropertyCondition(
        ScrollPattern.VerticallyScrollableProperty, true);

    // Use any combination of the preceding conditions to 
    // find the control(s) of interest
    Condition condition = new AndCondition(
        conditionSupportsScroll,
        conditionHorizontallyScrollable, 
        conditionVerticallyScrollable);

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