How to resize comments in XlsIO?
Comments are used as notes for a cell in a worksheet. The comment shape size can be resized by changing the height and width. XlsIO provides support for changing the width and height of the comments.
To resize the comment, please set the height and width of the comment like the following code snippet.
// Add comment in cell 'A1' ICommentShape comment = worksheet["A1"].AddComment(); comment.Text = "Resized comment"; // Height and Width measured in points comment.Height = 100; comment.Width = 100; comment.IsVisible = true;
To know more about comments in XlsIO, please refer the documentation.
