R – Sorting in Advanced Datagrid

actionscript-3apache-flexflex3

I have a Advanced Datagrid with sorting. I think it is string sorting by default. But I need the sorting in number. How can I achieve the number sorting?

For example: I have row numbers like 1 to 100 . I need number sorting like 1,10,100.

in your advancedDataGridColumn add a sortCompareFunction:

<mx:AdvancedDataGridColumn sortCompareFunction="NumberSorter" 
sortDescending="true" dataField="number" headerText="Formal Name" width="280"/>

Add the function somewhere in your scripts

<mx:Script>
    <![CDATA[

        import mx.utils.ObjectUtil
        public function NumberSorter(itemA:Object, itemB:Object):int{
        return ObjectUtil.numericCompare(itemA.number, itemB.number);
    }

    ]]>
</mx:Script>

I think all you need is for the given itemRenderer to include an Image object. You would set the .source property of the Image to data.imageURL (or some similarly named property on your data object).

Apache – Drag&Drop in Advanced DataGrid

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.
