The example shown here is for a Grid View, but the same types of event handlers must be implemented in roughly the same way for other data controls including the Form View, Details View, and List View. This is the final Grid View markup, so you can see the event handlers we’re going to implement.

NET 2.0 most of the examples and tutorials deal with setting the Data Source ID, which buys you a lot of automation that you may not even appreciate unless you’ve done this the old fashioned way.

Net gives the error "The Grid View event Row Deleting wasn't handled" could be encountered by the developer.

Normally we creat a Row Deleting event to overcome this error. The answer is that when you are trying to delete a row using a Row Command event with a command name of delete for your delete button Grid View itself finds that a Row_Deleting event is going to be called and waits for it but we haven't created it so the error is thrown when deleting the row that the Row_Deleting event is handled. Alternative Solution Instead of creating a event of Row Deleting, there is a best practice that you should change the command name from delete to something else like Delete_Product or something else.
