creating gridview with lookup view

HI, I need to create about 8 gridviews for a project. All grid view has to have the following features>>> add/edit/ delete/ sort/ paging/ and filter
The add and edit has to be in a popup screen. Some of the fields are a lookup table, which means the popup forms( for add and edit ) has to have a drop down list  for a user to select.
 Does anyone has a  complete sample code  that I can utilize in my development.
P.S. I am using 3 tier web app, so I cannot use sql Datasource.
Thanks
