TdxSpreadSheetHistoryAction.Undo Method

Rolls back all commands recorded as the history action and returns the opened spreadsheet document to the previous recorded state.

Declaration

procedure Undo;

Remarks

This procedure calls the Undo procedure for every stored change command and moves the history action from undo to the redo action list. An Undo procedure call has no effect if the history action is not last in the undo list.

Note

A spreadsheet control’s History.Undo procedure calls the Undo procedure internally for the last history action in the undo list.
