My confusion is because I'm not sure exactly how to get access to the column from the item renderer. I'm using data[DataGridListData(listData).dataField] to access the data to make reusable, but don't see any way via data or listData to get a reference to the column. If there's another way to get at itemToData or the dataTipFunction, I'd love to hear it.
