I have a dashboard UI with excel import and excel export buttons. Once each process is complete, I change a global variable on the dashboard to let the user know that the import/export is complete. I am deploying the simulation through the webserver and hence there is no way for the user to know if the import/export has completed. There is a on import code in the excelimport UI which allows be to do it for the import button. But no such option exists for excel export UI. Please suggest a way of doing it.
