Since R2 2022 the Spreadsheet control supports working with comments.

Comments are used for leaving information about a cell's data, where each comment can be replied to, thus creating a thread. All Comments can be found in the Comments collection of the worksheet. More information about using Comments in code is available here: SpreadProcessing Comments.

  • Reply Comment: Adds a reply to an existing comment. This option is only available when the selected cell already contains a comment.
  • Delete: Deletes the comment in the selected cell, including all of its replies. Only available when the selected cell already contains a comment.
  • Previous Comment: Selects the previous Comment in the current worksheet.
  • Next Comment: Selects the next Comment in the current worksheet.
