UpdateMode Property

Selects which fields are sent on update: all, changed, or full refresh.

Syntax

property UpdateMode: TwsDatasetUpdateMode read FUpdateMode write FUpdateMode;

Default Value

—

Remarks

Controls the payload sent to the server when a row is updated:

• upWhereAll (default) — every field of the row is transmitted, letting the server use any field for optimistic concurrency.
• upWhereChanged — only fields that have actually changed are transmitted, which reduces bandwidth but requires the server to match rows by key fields only.
• upRefreshAll — after sending the update, the client requests a full refresh of the DataSet so any server-side changes are pulled back.

Example

oProtocol.UpdateMode := upWhereChanged;
