How can a Spotfire data table be sent to a web service as csv and then replace the data table with the service response?
I have addressed the similar problem but I was using different approach than the proposed IronPython script behind a button.
In my case I created a standalone C#/ASP.NET web application and I have embedded the Spotfire Web Player into the application.
I used the Spotfire JavaScript API to pick up the data marked by user within the Spotfire Web embedded part and then send it via JavaScript call to webservice on the application. The webservice did some processing and sent the data to other destination. 
So my scenario was a bitt different but for yours you would also consider using the approach to embedd Spotfire Web into some app that you have full control over rather than using the IronPython script.
I need to send my Spotfire data table to a web service as csv and then replace the data table with the service response. I assume that this can be done with IronPython behind a button. Any ideas how?
