    Cell Comments
    In This Topic

    SpreadJS supports comments in cells. You can specify the appearance and resize, move, or edit the comment.

    You can add a comment to a cell and specify the appearance. You can also resize, move, or edit the comment.

    Cell comment

    The following image displays the resize and move indicator icons. The resize icons are displayed when you select the comment. The move icon is displayed when the pointer is over the comment border.

    You can lock the comment events or the comment text if the sheet options.isProtected method is set to true. The following table displays the comment property values and the result if the sheet is protected.

    Locked LockText Result
    false false Actions on comment take effect; the comment can be edited
    true false Actions on comment do not take effect; the comment can be edited
    false true Actions on comment take effect; the comment cannot be edited
    true true Actions on comment do not take effect; the comment cannot be edited

    Resizing a row or column can cause the comment's location and size to change based on the settings for the dynamicMove and dynamicSize methods. The following table displays the result of the dynamicMove and dynamicSize settings.

    DynamicMove DynamicSize Result
    true true Comment is moved and sized with cells
    true false Comment is moved, but not sized with cells
    false true or false Comment is not moved or sized with cells

    You can cut, copy, or paste text in the comment if the comment is in edit mode. The comment is copied with the cell if you copy the cell.

    The undo and redo actions apply if you cut, copy, or paste comment text, resize or move the comment, or change the comment's format.

    There are some limitations when importing a comment from an Excel-formatted file. Some border styles and fonts are not imported. The comment location may be different if the sheet range is smaller than what is displayed in the original file. Comments are imported from XLSX files.

    Using Code

    The following code adds a comment to a cell and sets the color and display mode.

    JavaScript
    Copy Code
    var comment = activeSheet.comments.add(5,5,"new comment!");
    comment.text("new comment!");
    comment.backColor("red");
    comment.displayMode(GC.Spread.Sheets.Comments.DisplayMode.AlwaysShown);
