Some other Grid Views reserved key words and their default associated events are as follow : “Cancel” – Raises the Row Canceling Edit event.
“Delete” – Raises the Row Deleting and Row Deleted events. “Page” – Raises the Page Index Changing and Page Index Changed events.
As our code does not handle those events hence they throw an exception.
The simplest solutions for this error is : Just change the “Command Name” property of the “Edit” button from “Edit” to “Edit Row”(or something else which is relevent to you but make sure it is not “Edit”). After scratching my head for sometime I found that the words like “Edit” are reserved to invoke some built in functionality of the Grid View.
So when we use these special key words as the Command Name for the buttons in the Grid View, they automatically invoke the built in functionality of the Grid View when we click on the button.
Please review the stack trace for more information about the error and where it originated in the code. Format Exception: Input string was not in a correct format. Command Text = "UPDATE objectdiary set shortdescription = @description where objectdiaryid = @objectid" Line 51: cmd.

Row Updating event, doesn’t work as all samples say it should do.
