Also note that MoveOnlyList is the name of the component I created as in Dante’s example, so that items are never copied, always moved (my experience was that the destination list was the controller, so any list that received items had to be a MoveOnlyList).

private function moveRight( destList:MoveOnlyList ):void {
    var item:Object = listOnTheLeft.selectedItem;
    if ( item ) {
        var acSource:ArrayCollection = ArrayCollection( listOnTheLeft.dataProvider );
        var idx:int = acSource.getItemIndex( item );
        var acDest:ArrayCollection;
        if ( destList.dataProvider == null ) {
            acDest = new ArrayCollection();
            destList.dataProvider = acDest;
        } else {
            acDest = ArrayCollection( destList.dataProvider );
        }
        acDest.addItem( item );
        acSource.removeItemAt( idx );
    }
}

Is possible to use some components which supporting draggin events in native AS3?
Have you got some?

Thanks for any help

I have 2 list controls and am dragging from one to the other. This is all fine. The target list is configured to use an XMLList variable as it’s data provider.

When the list only contains 1 dropped item, the dataprovider is EMPTY.

When it contains > 1 item, the dataprovider contains the XML that I expect it would, namely the representation of the data that has been dropped.

DataGrid shows the same issue.

Any ideas?

Thanks for any help,

This is a little rough, but should work:

I an developing an application with a datagrid, which is populated dynamically as a result of a HTTPService request, creating the columns and inserting the rows. This request is triggered by a drop event from a list.
My idea was to remove columns from the datagrid, causing the data (column + rows) to refresh, by dragging a column “out” of the datagrid, but i don’t know if such thing is possible… Can anyone help me? Thank you!
