Hi All,
In my asp.net application, i have file upload control from where i can upload any file to the server and  then uploaded files are shown in grid view on the screen with the name of the file as a link. I can click on the link and open the file.
Now, the user is reporting me the error that when he is opening the excel sheet (.xlsx) that was attached earlier, it is getting opened in 'protected' view and READ ONLY mode. And when he clicks on 'enable editing' button, it shows the error that "could not open ................... (file location)". 
When i am trying same thing, its working fine for me..... and it doesn't even opens in 'protected' view.
Any help please...!!!

Go to the complete details ...
