event is raised when a row's Update button is clicked, but before the Grid View control updates the row.
This enables you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs.

For this situation, many developers use invisible columns (Hidden columns) in the gridview to identify that row.
One of the issues I’ve had is that the edit template doesn’t map to the view template very well. You see, the data that gets stored back to the database during the edit could go to two of four different tables.
But the view is generated from a stored procedure that gathers the information from those tables and makes the result look like it came from one table. NET, C#, Node.js, Java Script, HTML, CSS, Boot Strap, and Angular. Does your team need additional help in any of the above?
When I click edit on the grid and change the value of the textbox and click update the label will just display the original value of the textbox. "When I click edit on the grid and change the value of the textbox and click update the label will just display the original value of the textbox." So lets say there is "test" in the textbox originally and then I edit it to "asd" then click update.
before that i want just using Find control and casting and then retrieving all lot code. If values are same they could notify user to change the value(give new cell value).
