Worksheet.Calculate not retriggering call to RTD server. C#
===

I am trying to trigger calls to the addTopic method of my RTD server by using the worksheet.calculate method. However the RTD server is not getting hit. I need resend all topics to the RTD server as part of retry logic if an exception gets thrown while I am trying to process topics.

Any ideas as to why Worksheet.Calculate is not working or thoughts on how i can force excel to resend all topics will be appreciated. The code i am using is below

     Application.CalculationMode = xlManual
     Worksheet.Calculate
     Application.CalculationMode = xlAutomatic
