Setting the RowCount and ColumnCount in a Flex 3 TileList

Question

Hi,

I'm using the TileList in a Flex 3 website. I need to set the rowCount and columnCount to factors of the total number of items in my array. For example, let's say that there are 15 items in my array. Then, I'd like to set the rowCount to 3 and the columnCount to 5 (3x5=15). Or if I had 16 items in the array, then I'd like to set the rowCount to 4 and the columnCount to 4 (4x4=16). The problem is that the length of the array varies. It's pulled from a database.

Any suggestions on how to handle this problem?

Thank you.
