Gets the current UI Automation property values for this ExpandCollapsePattern.
Assembly: UIAutomationClient (in UIAutomationClient.dll)
This pattern must be from an AutomationElement with an Full reference in order to get current values. If the AutomationElement was obtained using None, it contains only cached data, and attempting to get the current value of any property raises an exception. Use Cached to get the cached value of a property that was previously specified using a CacheRequest.
For information on the properties available and their use, see ExpandCollapsePattern.ExpandCollapsePatternInformation.
