i am stuck in scenario, i have display record, if i want to edit then i click edit and it goes into edit mode, passing UserID to another page, EDIT page shows Textboxes, dropdowns to be edited, lets suppose i want to edit 3 fields out of 6 then how to keep old values for which i am not inserting or selecting anything because if i don't select/put any value then it will put null into that column in DB, so how to prevent and update only desired fields ?

From the Question , it seems that you are bit confused on the Edit functionality on the Page. Usually , Edit Page should be Populated with the Existing Value . So there is no question of inserting Non Changed fields as NULL into the DB unless its been removed by the User.
