R – Flex : Displaying the Advanced DataGrid data in Pages

Assuming you don't need to dynamically get the data once a certain scroll position is reached, you just need to update the verticalScrollPosition property.

Check out Creating an auto-scrolling DataGrid control in Flex on FlexExamples, I think that's exactly what you're asking.

If you had a dataset that was 100 items and wanted to tween it down to the last one, using TweenMax, you could do something like (though I'm not sure exactly how the datagrid gets the max scroll position:

TweenMax.to(dataGrid, 1, {verticalScrollPosition:dataGrid.maxVerticalScrollPosition});

Hope that helps!

Of course this is possible. Add a dragEnter Handler to your datagrid:

<mx:AdvancedDataGrid id="adg" dragEnabled="true" dragEnter="adg_dragEnterHandler(event)" />

With the following code:

protected var _draggedItem:Object;

            protected function adg_dragEnterHandler(event:DragEvent):void
            {
                event.preventDefault();
                event.currentTarget.hideDropFeedback(event);

                var items:Array = ds.dataForFormat("items") as Array;
                if (items != null && items.length > 0 && (items[0] is CategoryVO)) {
                    _draggedItem = Object(items[0]);
                }

                // Prevent item from being dragged
                if (_draggedItem.property == true) {
                    DragManager.showFeedback(DragManager.NONE);
                    return;
                }

                DragManager.acceptDragDrop(UIComponent(event.currentTarget));

            }

_draggedItem.property == true is the check, if an item can't be dragged.
