Help w/ DataGrid update for Database Tables in SQL

Question

I am working in C# and running an Oracle 9i server. I was just wonering if there is a shortcut way of updating my tables and not have to build special front end for it. What I would like to do is update the tables that I have pulled from the database in the data grid (in a form window), modify the tables, add users, information, then use a button to update the new information added in the datagrid. I would also like to be able delete records in this manner. I have an example in a text book, but it involves reading the data, converting it to text boxes, then updating it. This is all fine and dandy, but I would rather work with it in the grid and not text boxes as I don't need the pretty boxes or labels. Any help would be great! Thanks in advance! Brad Britton
