FieldChangedHandlers

Protected ReadOnly Property FieldChangedHandlers As Blackbaud.AppFx.BatchUI.BatchEntryHandler.FieldEventHandlerCollection(Of Blackbaud.AppFx.BatchUI.CellDataUpdatingEventArgs)

FieldChangedHandlers has an Add procedure to add a FieldEventHandler for a particular field within the batch grid user interface. When the assigned field changes, the AddressOf operator designates a delegate to handle the event. The AddressOf operator creates a function delegate that points to a function specified by the procedure name.

Or you could define this in the BatchEntryHandler_AfterLoad event.
