DataTable.RowDeleting Event

Occurs before a row in the table is about to be deleted.

Namespace: System.Data
Assembly: System.Data (in system.data.dll)

'Declaration
Public Event RowDeleting As DataRowChangeEventHandler
'Usage
Dim instance As DataTable
Dim handler As DataRowChangeEventHandler

AddHandler instance.RowDeleting, handler

/** @event */

JScript supports the use of events, but not the declaration of new ones.
