Event Data

The BatchUpdate event's data class is ASPxDataBatchUpdateEventArgs. The following properties provide information specific to this event:

Property	Description
DeleteValues	Returns a list of deleted values.
Handled	Specifies whether the ASPxGridBase.BatchUpdate event is handled.
InsertValues	Returns a list of inserted values.
UpdateValues	Returns a list of updated values.

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.
