DetailsView.ItemDeleting Event

 

Occurs when a Delete button within a DetailsView control is clicked, but before the delete operation.

Namespace:   System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

member ItemDeleting : IEvent<DetailsViewDeleteEventHandler,
    DetailsViewDeleteEventArgs>

The ItemDeleting event is raised when a Delete button within the DetailsView control is clicked, but before the delete operation. This allows you to provide an event handler that performs a custom routine, such as canceling the delete operation, whenever this event occurs.

A DetailsViewDeleteEventArgs object is passed to the event handler, which allows you to determine the index of the record being deleted and to indicate that the delete operation should be canceled. To cancel the delete operation, set the Cancel property to true. You can also manipulate the Keys and Values collections, if necessary, before the values are passed to the data source.

For more information about handling events, see NIB: Consuming Events.

The following code example demonstrates how to use the ItemDeleting event to cancel the delete operation if the user attempts to delete the last item from the DetailsView control.
