dataProvider:Object
Versione linguaggio: | ActionScript 3.0 |
Versione prodotto: | Flex 3 |
Versioni runtime: | Flash Player 9, AIR 1.1 |
The set of items this component displays. This property is of type Object because the derived classes can handle a variety of data types such as Arrays, XML, ICollectionViews, and other classes. All are converted into an ICollectionView and that ICollectionView is returned if you get the value of this property; you will not get the value you set if it was not an ICollectionView.
Setting this property will adjust the selectedIndex
property (and therefore the selectedItem
property) if
the selectedIndex
property has not otherwise been set.
If there is no prompt
property, the selectedIndex
property will be set to 0; otherwise it will remain at -1,
the index used for the prompt string.
If the selectedIndex
property has been set and
it is out of range of the new data provider, unexpected behavior is
likely to occur.
