How to use AutomationID in nameMapping to identify WPF objects uniquely

Thanks for your reply first, I got it.

Another question I want to ask is how to add AutomationID  as the default property? From TestComplete's website, it says that for the object "ObjectIdentifier"

"The value of one of the following native properties of the object (ordered by priority):

• Name

• AutomationID

• ClassName"

please refer to; https://support.smartbear.com/testcomplete/docs/reference/test-objects/members/uia/objectidentifier-property-uia-object.html?q=objectIdentifier#_ga=2.168242209.1802664049.1494696455-134552010.1466044916

I want to use AutomationID as the default value of the "ObjectIdentifier", so that I don't need to add the "AutomationID" manually for each object each time, that would be saving time greatly.

Thanks,
