Undo/Redo

Feature Description

The Undo/Redo options allow users to revert and reapply previous update operations on an attribute table.

Configure maximum rollback limits for attribute table editing operations in the Settings under the Edit group.

Max rollbacks: When checked, the max rollbacks setting becomes active. The text box on the right specifies the maximum number of redo/undo operations allowed for attribute table edits.
When the number of redo/undo operations exceeds the set max rollbacks, users cannot revert subsequent edit operations.

If attribute table edits exceed the max rollbacks during an update in the Update Column dialog, a warning will appear: "The history has reached maximum rollbacks. This update will prevent the earliest operation from being rolled back. Continue?" Click Yes to proceed or cancel the operation.
Max objects: When checked, specifies the maximum number of objects affected by a single rollback operation.
During updates in the Update Column dialog, if the number of modified records exceeds the Max Objects limit, a warning appears: "The number of updated objects exceeds the maximum per-rollback limit. This operation cannot be rolled back. Do you want to continue?" Click Yes to proceed or cancel.
Show warning when rollbacks cannot be performed: When checked, displays warning dialogs when edit operations exceed rollback limits due to frequency or object count.
If unchecked, edit operations exceeding these limits will fail silently without warnings.
