Can anyone tell me the best way to update a dataset while it is being edited/viewed in the Data Grid View control? Also, can you tell me the best book to buy that fully explains the Data Grid View control? I've got the datagridview working pretty well in the first draft of my program, and I'm not using Accept Changes at all. or should you update after closing the grid/form, etc.?
Is this something that should be inserted into one of the grid's events? I just use the Update method of the data Adapter when I'm done. Also, can you tell me the best book to buy that fully explains the Data Grid View control?

In this article, I am going to take a simple database table that has following fields: Auto ID - Int, Auto Increment, Primary Key Page Name - Varchar(50) Page Description - Varchar(500) Active - Bit(1) In this article, I am not going to explain the workings of Sql objects but focusing on the events and methods of the Grid View that will help us in updating and deleting the records.
This article scope is limited to Updating and Deleting records using Grid View and I am not using any readymade Data controls for that but manually writing all event methods.
I will be using Sql objects directly into methods to keep the example simple and straight forward.
