Assembly: System.Web (in System.Web.dll)
Initializes a new instance of theclass.
Gets the number of rows affected by the delete operation.
Gets the exception (if any) that was raised during the delete operation.
Gets or sets a value indicating whether an exception that was raised during the delete operation was handled in the event handler.
Gets an ordered dictionary of key field name/value pairs for the deleted record.
Gets a dictionary of the non-key field name/value pairs for the deleted record.
Determines whether the specified object is equal to the current object.(Inherited from Object.)
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
Serves as the default hash function. (Inherited from Object.)
Returns a string that represents the current object.(Inherited from Object.)
The FormView control raises the ItemDeleted event when a Delete button (a button with its CommandName property set to "Delete") within the control is clicked, but after the FormView control deletes the record. This allows you to provide an event-handling method that performs a custom routine, such as checking the results of a delete operation, whenever this event occurs.
A AffectedRows property. Use the Exception property to determine whether any exceptions occurred. You can also indicate whether the exception was handled in the event-handling method by setting the ExceptionHandled property.object is passed to the event-handling method, which allows you to determine the number of records affected and any exceptions that might have occurred. To determine the number of records affected by the delete operation, use the
