    You can’t.

    But you can do this:

    List<string> list = (List<string>) btnKats.DropDownItems;
list.Sort();
btnKats.DropDownItems = list;

    The rationale is that DropDownItems is a ToolStripItemCollection that implements a plain IList (of objects). As objects are not naturally comparable, you can’t sort an IList, but you can cast it to a List<string> and sort it.

    Good luck!
