I am using WF 8.0 on window, I have a dashboard portal with multiple tabs. One of the tab will display an excel formula output. Currently, when lunch the tab, the excel output will not display automatically, instead, it shows the message : “Do you want to open or save xxxxx.xlsx from “server_name ”? with open Save cancel three buttons.

Our user has to click the open button, then the excel will open in a new window.

Is there a way to let the xlsx formula report automatically open and open within the portal frame? My browser is IE9 Thanks,
