Well this is my question.
I use Response.Writefile("Test.xls") and this code generate two options "Open" and "Save " , when the user click open , he can see the file , but if the user wants save with excel , doesnt work because the file is load in temporal folder (AppData\Local\Temporary Internet Files\)
How can I save modifications from excel directly on server after useresponse.writefile?
