TdxSpreadSheetContainer.BeginChanging Method

Initiates recording of a custom history action applied to the floating container to the UndoActions list.

Declaration

procedure BeginChanging;

Remarks

In order to undo and redo multiple floating container modifications as a single action, enclose the code that performs these modifications between the BeginChanging and EndChanging procedure calls that must be enclosed within the BeginUpdate/EndUpdate procedure block. Otherwise, invoking the BeginChanging and EndChanging procedures has no effect.

Ensure that every call to BeginChanging is followed by a call to the EndChanging procedure. Otherwise, no new actions can be added to the UndoActions list.

Note

Calling the BeginChanging procedure has no effect if the history functionality is disabled.
