FlashBuilder 4 is planning a new ItemRenderer wizard/tool to help folks create ItemRenderers for Spark List controls. Because Spark doesn’t yet have a Tree or DataGrid, and because MX Tree and MX DataGrid have a different ItemRenderer contract, the new tool will not be usable in all list-type controls and folks will have to learn both ItemRenderer contracts.
Much of the drag and drop functionality is the same for the Spark and MX list-based controls. However, there are a few differences please access follow page for detail
