Problem using gridview in tha time of adding

Hi,

I want to develop a program using GridView in asp 2.0. I want to implement add, modify, delete functionality in GridView. I want to add textbox and ddl in footer. There is Add button in the Footer. When I click the Add button the data from footer will be displayd in the grid. But no data will be added in the database. I also want to modify data in the grid and also delete. When there is no data in the grid nothing is showing not even footer.

Any help will be gratefully accepted.
