Update SQLdatasource from dataview

Through code, i calculated values that i want to show to the users.
But i stored them in a dataview, in a specific column that came up blank from sqldatasource.

After calculating this values and store then in the dataview, i want to know if a can update the sqldatasource with the new values from the dataview.

And why?

My real problem isn't bind the dataview to the gridview. The problem is if I have an sqldatasource feeding my gridview, the sorting is almost automatic.
But with the dataview it does not work. And I can't able to do it. I searched how to do it but nothing. I can't make it. :(

Thank you for your reply.

In practical terms, what i want to do is something like this at the end of my routine:

sqldatasource = dataview (basically is refreshing the datasource with the new values that are store in the dataview)

gridview.datasource = sqldatasource
gridview.databind()

I'm not shure if is possible to do it.
