Remarks
The batch edit mode allows modifying a batch of grid data on the client side and sending it to the server in one request on clicking the Update button. You can use the BatchUpdate event to provide a custom data update mechanism.
Set the ASPxDataBatchUpdateEventArgs.Handled event argument property to true to indicate that the BatchUpdate event is handled, and therefore no default processing is required.
The ASPxDataBatchUpdateEventArgs.DeleteValues, ASPxDataBatchUpdateEventArgs.InsertValues, and ASPxDataBatchUpdateEventArgs.UpdateValues properties return lists of deleted, inserted, and updated values respectively.
