Pattern Field

WindowPattern.Pattern Field


Identifies the WindowPatterncontrol pattern.

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

public static readonly AutomationPattern Pattern

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

The pattern identifier is passed to methods such as GetCurrentPattern to retrieve the control pattern of interest from the specified AutomationElement.

In the following example, a WindowPatterncontrol pattern is obtained from an AutomationElement.

/// <summary>
/// Obtains a WindowPattern control pattern from an automation element.
/// </summary>
/// <param name="targetControl">
/// The automation element of interest.
/// </param>
/// <returns>
/// A WindowPattern object.
/// </returns>
private WindowPattern GetWindowPattern(AutomationElement targetControl)
    WindowPattern windowPattern = null;

        windowPattern =
            as WindowPattern;
    catch (InvalidOperationException)
        // object doesn't support the WindowPattern control pattern
        return null;
    // Make sure the element is usable.
    if (false == windowPattern.WaitForInputIdle(10000))
        // Object not responding in a timely manner
        return null;
    return windowPattern;
