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.
