Which is the recommended way to fill all controls on a Web Form when user selects a record?

I have a GridView control which shows a list of all employees. When user selects any employee from this list, the record is shown on a Web Form with all input controls pre-filled with the values.

I want to know any good approach to do this. Should I bind all input controls to any SqlDataSource or should I re-populate all input controls by picking values from the DataSet.
