I have a TileList that's loaded with data from Flickr. The tilelist uses an imageRenderer to make a bunch of thumbnails. I'm trying to create a custom drag and drop function, but I want to get the image source of the tilelist mouseEvent target. Here's what the code looks like for the drag handler:

I'm in need of some dire help here. I'm writing an application in Flex 3 that utilizes a TileList with a custom itemRenderer to display info from a service. Unfortunately, I'm running into an exception with the drag/drop/rearrange portion of the TileList. With dragEnabled and dragMoveEnabled, I receive a fully-reproducible exception when trying to rearrange the tiles in the control:
Exception:
ArgumentError: Error #2004: One of the parameters is invalid.
at flash.utils::ByteArray/writeObject()
at flash.desktop::Clipboard/putSerialization()[code]....
When I try to debug, the debugger doesn't seem to indicate to me any piece of code that might be faulty.
I have two mx:TileList controls that I'm using to allow editing of objects in batch. The first contains a collection of all available data, and the 2nd contains the current batch. Both are bound to ArrayCollections, and using the native drag-n-drop functionality of the TileList control the data is moved from one ArrayCollection to the other when an object is dragged between them.
I need to change the currentState to show & reset the batch manipulation controls when the batch count goes from 0 to n or n to 0 items. Based on the documentation, I would have thought that I should listen to the dragComplete event, but my testing shows that instead of firing after the data has been removed from the source ArrayCollection and added to the destination ArrayCollection, it fires (consistently) between these two actions.

I need a way to drag and drop an image from a container to another. I have tried a few different ways but I guess the drag & drop thing is still eluding me. Anyway, here's what I am trying to do, A container will contains a few bitmap/vector image (what's the best way for this? Tile Group? Or?) and then I want to be able to drag any of the image onto another larger Image inside of a Panel. Just like dragging shapes in Photoshop. No code here, as I am completely lost on how to go about it. I found a few tip/tutorial here and there but none which I could understand easily or adapt to my need.
Edit 1 : Got so far till now :
public function beginDrag( mouseEvent:MouseEvent ):void

I am implementing drag and drop from a DataGrid onto a List in a Flex 3 AIR application. I would like to have the drag image be a photo (jpg) referenced by a String field in the data grid item, named 'imagePath'. I'm having trouble getting the image to show up during dragging. I have triple checked that it is not because of an invalid path to the image. I have tried Image's source() and load() methods in every way I can think of. I am calling this method 'dragCurrentToList(event)' on a mouseDown event.[code]This works perfectly if I set the image source to the following bindable variable but I don't want to hardcode the image name.[code]
View 1 RepliesI have a DataGrid that contains data linked to a server. When I select mutliple items from the grid (using shift-select) and drag some items out from the DataGrid to another component, the array of items being dragged over appears to be in a completely arbitrary sort-order, and are not in the sort -order f the DataGrid as I'd expect.
Therefore, wwhen i drop them on the target (which is unsorted), their order doesnt match that of the DataGrid... what am I doing wrong and how can i fix this?
I'm getting the array using:
var dragItems:Array = event.dragSource.dataForFormat("items") as Array;
Is this the wrong data source on dragSource to look at?
I should mention that the drop target is a nonlist control, and that i am using a custom drop handler...
I want to have an image and when I click on the image ,one can hold down the mouse and drag a copy to where ever on the stage and when one lets go, one can drag another and another with each copy still being able to be dragged after released.this is what i have but its pretty simple and doesn't work....
stage.addEventListener(MouseEvent.MOUSE_DOWN,makeA Box);
var i:Number = 1; //i will be the total number of boxes
var newBox:myMC = new myMC();[code]....

View 2 Repliesim working on a website at the moment (just for fun) and are done with the layout and almost everything. Now I want to make one of the pictures so you can drag and drop it around on the site. The problem is that it does'nt work, i've tried out many different tutorials and codes without success. Sometimes i get the 1120 error and when not, nothing happens.

I have a very simple question, but I can not find solutions to it. I need to add multiple images that can be moved with the mouse. This components NumericStapper must be in the group with the image and move together.[URL]
View 1 RepliesI'm running into an odd issue with itemRenderers inside a TileList.Here is a working example without an itemRenderer: 152.org/flex/
Here is the broken version with an itemRenderer: 152.org/brokenExample/. (I don't have the rep to make both of these a link)Both examples have "View Source" enabled.To see the problem use the broken example, select an album and scroll down one row. Scroll back up and the images will be switched.If you try this on the working example it's fine.This seems to be a widely known bug, but I can't find a solution for it.
UPDATE: I started playing with this example again and found out something else. Turns out you don't have to override the data setter. You can create a new method in the itemRenderer that is set whenever the tile wants to refresh. So the trick is to not rely on the initialize or creationComplete methods.This is what I have for the itemRenderer in the Application.
<itemRenderers:ImageTile img="{data}"/>
This is the code I have in the itemRenderer.
public function set img(value:String) : void {
trace("setting source: " + value);
this.source = value;[code]....
I updated my example to reflex this change.
This is what I used to load an external image into a movie clip and drag and drop. The feedback part is pretty much the same from the old code.[code]...

View 3 RepliesI have run into a drag and drop issue .I have an item that I would like to drag and drop. Seems simple enough, but I also want to make it that if the user drags the image off the screen, that it stops dragging and returns the image to the center of the screen. What happens now is that it continues dragging and sticks to the cursor if you release outside of the viewable area. The original piece has a lot of other things going on, so I ve created a simple piece with the AS in the timeline that shows only this particular issue.
Code:
var mrT:MC_mrT = new MC_mrT;

View 2 RepliesI'm doing an application in flex where I draw different sprites inside a canvas. Depending of the dimensions, scrollbars can be appear. I would like to move the "image" with the movement of the mouse as you can see at the Adobe Reader when you are reading a document with zoom (hand mouse icon). In this way, you dont have to touch the scrollbar.I'm start trying with drag and drop properties of the canvas, setting the position of the scrollbar according with the movement of the mouse but that is not as I expect.
View 2 RepliesI am dragging item from a datagrid and while dragging I could see all of the columns in the selected record, being getting dragged.

View 1 RepliesI am building a flex project involving drag+drop of fxg graphics. My graphic is instantiated as below:
<graphics:arrow2 id="object" mouseMove="mouseMoveHandler(event);" />
I get an error: "Call to a possibly undefined method Graphic."
This works if I change my drag-object to Image and replace the 'Graphic' below with 'Image'. What should I use to be able to reference the fxg graphic in the drag-drop? My drag drop functionality is as follows
private function mouseMoveHandler(event:MouseEvent):void {
var dragInitiator:Graphic = Graphic(event.currentTarget);
var ds:DragSource = new DragSource();
ds.addData(dragInitiator,"gph");
DragManager.doDrag(dragInitiator, ds, event);

I have implemented drag and drop between 2 AdvancedDataGrid, but the default behaviour from Flex displays the row data during the drag using the grid item renderer showing all 5 columns.
Instead, I would like to display an icon / image or my own custom item renderer during the drag and drop.
How do I determine which Flex AdvancedDataGrid cell - row and column index - I've just dropped onto? calculateDropIndex seems to give me the row, but how do I get the column?
