FormViewDeleteEventArgs Class
Provides data for the ItemDeleting event.
Assembly: System.Web (in System.Web.dll)
The FormView control raises the ItemDeleting event when a Delete button (a button with its CommandName property set to "Delete") within the control is clicked, but before the FormView control deletes the record. This allows you to provide an event-handling method that performs a custom routine, such as verifying a record before deleting it, whenever this event occurs.
A FormViewDeleteEventArgs object is passed to the event-handling method, which allows you to determine the index of the record being deleted and to indicate that the delete operation should be canceled. To determine the index of a record, use the RowIndex property. To cancel the delete operation, set the Cancel property to true. You can also access the key fields and non-key fields by using the Keys and Values properties, respectively. These values are useful if you want to verify the record before deleting it.
Note: |

It is possible to modify the key field values and non-key field values in the Keys and Values properties, respectively. If you change these values, the record that corresponds to the new values will be deleted. |

The following example demonstrates how to use the FormViewDeleteEventArgs object passed to the event-handling method for the ItemDeleting event to cancel a delete operation.
