C#

this.comments.Value += row["messages"].ToString();

this.comments.Value = Environment.NewLine;

Perhaps if the second line was also "+=" rather than "=" it would make a difference?

BTW: it would make a lot of sense to replace the this.comments.Value with a StringBuilder - particularly if there are expected to be a lot of rows - remember that strings are immutable in C# so you create a new string every time you concatenate two of them.
