Tile Direction property

The Tile Direction property specifies the main direction in which the infocon component is to expand when the drop-down arrow is clicked.

Valid values are [Down], [Up], [Right], and [Left].

We say "main direction" because, for example, if the user has specified [Down] with the [List Columns] property set at [2] tiles, the resulting display will be two tiles wide and then expand downward as space permits.
