Don,

Typically the .DisplayMember will be from the DataSource, not from the Bound data. I'm assuming that you did it this way because your arraylist has only one dimension. I've not found an easy way to use an array as a DataSource when your DisplayMember and ValueMember are two different things (I may be missing something) ... in those cases, I've just built a Table instead of an Array and used the Table for the DataSource.
