private DockPattern GetDockPattern(
    AutomationElement targetControl)
{
    DockPattern dockPattern = null;

    try
    {
        dockPattern =
            targetControl.GetCurrentPattern(
            DockPattern.Pattern)
            as DockPattern;
    }
    // Object doesn't support the DockPattern control pattern
