|GetHashCode||Serves as the default hash function. (Inherited from Object.)|

The ListView control raises the ItemEditing event when an Edit button is clicked, but before the ListView item enters edit mode. (An Edit button is a button whose CommandName property set to "Edit".) This enables you to provide an event-handling method that performs a custom routine whenever this event occurs, such as canceling the edit operation.
A object is passed to the event-handling method. This object enables you to determine the index of the item that is being edited, and to indicate that the edit operation should be canceled. To cancel the edit operation, set the Cancel property of the object to true.
For a list of initial property values for an instance of , see the ListViewEditEventArgs constructor.
The following example shows how to use the object to cancel the edit operation when the user tries to update a discontinued item.
This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.
