If you are moving up or down (resequencing), then you don't want to swap.
You should be able to use removeItemAt(), which returns a reference to the item removed, and addItemAt() to re-insert it. You may need to manipulate the indexes if you move an item "down", because removing the item causes the indexes to adjust. If you really want to swap, you should be able to do that also, again paying attention to the indexes. If you use the AC API, the UI should refresh itself. What issues are you having?

I am trying to impliment a 'move up' / 'move down' feature with arrows so a user can reorder rows in the datagrid. I know reordering can be done via drag and drop, but does anyone have an example of what would effectively be a method looking like as follows: XMLListCollection.swapItems(item1Index:int, item2Index:int); //where the method effectively takes the items at the given indexes and swaps them round The idea being that you change the List Collection and the datagrid reflects these changes automatically (as is standard behaviour with dataproviders). I can ALMOST get it working but i think it doesnt like more than one change to the collection at once and it may require a eventListener for the second part of teh swap. Any ideas / examples?
