I want to place a custom button on the Opportunity detail page. this button if clicked will pop all the record data into a excel sheet.
how do i approach this, i know how to export with content type and linking it to a button with pagereference, but i have tried all that in VF pages with custom controller only.
for opportunity, how do i create a button and place it and then link it to a vf page that exports all the data to excel sheet.
Thanks
