FORMVIEW
FormView is a new data-bound control that is nothing but a templated version of DetailsView control.
The major difference between DetailsView and FormView is, here user need to define the rendering template for each item.
Use the FormView control to:
Display
Insert
Edit
Delete
Page
Database records
The formView control is completely template driven
