Hello Ashbin,

Was this test running successfully before? If so are there any updates to your application since you face the thrown exception? Have you tried to re-record the failing step and execute the test again?

Please let me know some further details on the issue to continue the investigation. Thanks in advance!

Hi Ashbin,

You could try to locate the button using the highlight option in the recorder and locate the element in the DOM tree from the Elements menu. Then manually add an action step against the recorded element. 

Would it be possible to create a sample wpf application with the same control to replicate the issue? This will allow us to debug the occurred behavior and find out what might be causing it. 

Which is the version of Test Studio you have in place?
