As good or bad as the Java language may be, I think plenty of people are turned off by the Java culture that encourages this to happen. This is a little bit of an understatement since Sun setting the defacto coding standard gives a very strong message to followers.

Reading this, I would guess that it's a notification of when the user starts editing a column, and indeed that's what it does. "Informs the System.Windows.Forms.DataGrid that the user has begun editing the column." is the official description in the API.
IMHO it's not close at all. First, the namespace shouldn't be counted, leading to a huge difference in sheer length.

Third and anyway, this is the longest public class in the BCL, whereas the article describes an internal class; a much higher bar should be held for public names.
