Public Event NodeDeleting As ASPxDataDeletingEventHandler
The NodeDeleting event's data class is ASPxDataDeletingEventArgs. The following properties provide information specific to this event:
|Cancel||Gets or sets a value indicating whether the event should be canceled. Inherited from CancelEventArgs.|
|Keys||Gets a dictionary of field name/value pairs that represent the primary key of the row to delete.|
|Values||Gets a dictionary of the non-key field name/value pairs for the row to delete.|
The NodeDeleting event occurs when an end-user has clicked the Delete command button, or the ASPxTreeList.DeleteNode method has been called. To cancel the delete operation, set the event parameter’s Cancel property to true.
After a node has been deleted, the ASPxTreeList.NodeDeleted event is raised.
