Despite the richness and versatility of its programming interface, the ASP.NET 1.x DataGrid control requires you to write a lot of custom code to handle common operations such as paging, sorting, editing, and deleting data. For example, while the DataGrid control can raise events when the user clicks to save or cancel changes, it doesn't offer much more than that. If you want to store changes to a persistent medium, such as a database, you have to handle the UpdateCommand event yourself, retrieve changed values, prepare a SQL command, and then proceed from there to commit the update.
