Item renderers and item editors for list components must implement the IListItemRenderer interface. The IListItemRenderer interface is a set of several other interfaces. It does not define any new class methods or properties.

The set of interfaces includes the following: IDataRenderer, IFlexDisplayObject, ILayoutManagerClient, ISimpleStyleClient, IUIComponent. The UIComponent class implements all of these interfaces, except the IDataRenderer interface. Therefore, if you create a custom item renderer or item editor as a subclass of the UIComponent class, you only have to implement the IDataRenderer interface and then you can add to the class definition that the class implements IDataRenderer and IListItemRenderer.

IListItemRenderers are generally dedicated to displaying a particular field from the data provider item and cannot be re-used in other DataGrid columns or in other lists with different fields. If you want to create a renderer that can be re-used you can also implement IDropInListItemRenderer, and the list will pass more data to the renderer that allows the renderer to be re-used with different data fields.

Item renderers and item editors are passed data from a list class' data provider using the IDataRenderer interface. Renderers and editors that implement the IDropInListItemRenderer interface get other information from the list class. The item renderer or item editor uses one or both pieces of information to display the data.

The renderers and editors are often recycled. Once they are created, they may be used again simply by being given a new data and optional listData property. Therefore in your implementation you must make sure that component properties are not assumed to contain their initial, or default values.
