OK I have an AdvancedDataGrid. The data I feed it is XML that looks like this:
<stat associate="Sam Smith" date="07/08/09" customer="James Frank"/>
<stat associate="John Doe" date="09-07-08" customer ="Amanda Jones"/>
<stat associate="John Doe" date="09-07-09" customer ="Henry Scott"/>
But I am grouping by associate so it ends up looking like a tree like this:

I am trying to drag and drop hierarchical data in the same advanced data grid, and I would like the data provider to updated when the ADG is updated. (I want to be able to save and load this tree, so it is important that drags and drops are saved.)
[URL]
The sample app has an ADG showing hierarchical data as well as flat data. The first column of each datagrid shows the rowindex of the underlying data.
If you rearrange the items on the left ADG, the row indexes become unordered. If you click traceTree you see that the data provider is not in order.
On the other hand if you do the same on the right, the row numbers stay ordered even when the objects move around and if you click traceFlat, the data provider is in the order shown on ADG
My goal is to have the data provider order match the ADG order for the left grid which is displaying hierarchical data.
I have datagrid binded with data acquired from web service which, as you may suspectretrieves data from some db. Datagrid has some editable columns and I want to update db through appropriate web service call without adding button "Update" as a last column in datagrid.

View 1 RepliesI have a custom <mx:DataGrid /> that is updated with data from a ColdFusion server every 60 seconds. I've noticed that every time the DataGrid updates and redraws the scroll position is reset to the top.
Is there a way I can preserve the scroll position for my DataGrid?

In my Flex Project using Cairngorm, I have a model that stores a bindable ArrayCollection displayed by a DataGrid. My problem occurs when the model is updated by the responder (from a Java service, after an "update" event), because the focus located in a cell of the DataGrid is lost (the scroll position il also lost). So, I retrieve the position before the update, with DataGridEvent.ITEM_FOCUS_IN event :
myModel.focusedCell.rowIndex = e.rowIndex;
myModel.focusedCell.columnIndex = e.columnIndex;
But, from where restore these parameters ? How to trigger this update only when the model is updated ?
I have a Datagrid that is being populated by an ArrayCollection (rows) of Arrays (columns).I need to update the headerText of each column based on a List that will correspond with the total number of items within each array in the arraycollection. What is the best way of doing this? I know that I can set a listener in the List and update the headerText using (matrixDatagrid.columns[i] as DataGridColumn).headerText but I am looking for a cleaner solution.

How can i update multiple cells of the same row changing the value of a single cell of the same row ??
Example: id, height, weight, fat percentage, corporal mass. When i change one of the values in a row (except id of course) the corporal mass cell value must change using a formula like: (height/weight2)*fat percentage*100. Is this posible with Datagrid or AdvancedDatagrid in Flex ??
I tried using custom item renders and inserting actionscript code inside the datagrid with no good result.
Im working with a flex application that pulls data from a java class file using message handler event. The received message string is added to ArrayCollection. The string consists of codeID and other values related to codeID. Had displayed the detail in a datagrid. The codeID is randomly generated and is pushed to flex for every second. Now, the problem is, I needa update the datagrid cell values, for instance, if i have pushed codeID's of (0001,0007,0005,0003) to the front end, that displays the corresponding values of each codeID in the datagrid, second instance of (0001) should update records in the existing row of (0001). I tried to check the existence of codeID in ArrayCollection using search algorithm, but dont know how to proceed further.
View 1 RepliesI have a component A in my flex project where people can vote for their favourite artist. Someone "likes" an artist, it get's updated in my database. There is also a component B that shows a chart of the most liked artists. I call the data from the database on creationcomplete in Flex. The problem is that when a person first votes on an artist, it will not be visible in the datagrid untill the user reloads the main page (?) or reopens the entire application. So i was wondering how i can update the datagrid everytime someone adds a vote to my database. I'm now using an update button, but that's not very user friendly of course.

View 1 RepliesI'm trying to drag an item from a datagrid and drop it onto a UIComponet. Basically I just want the UIComponent to know that something has been dropped onto it and allow it to access the data of the dropped item.
I thought just listening for the drop event would do it but it seems not.
I found lots of documentation on dragging from one IList to another but nothing for this.
<mx:UIComponent xmlns:mx="http://www.adobe.com/2006/mxml"
initialize="init(event)" dragDrop="itemDropped(event)">
When I enter with a dragged item into datagrid, a bold line appears over the active row of the datagrid (which is fine to show the active row), but the problem is that even after I drop the item into datagrid, that line remains there. It goes only if I enter with a new item (in which case a new line comes to the respective row again).
I am using custom handler for dragdrop event for this datagrid.
I've got a Gridcolumn in a Datagrid (Spark). The Column's dataprovider is a Number value that gets updated via Binding.Now, without an item renderer the cell displays the correct values.If I set an item renderer, I can't access the values in this renderer.My renderer looks like this, so nothing really do here (for now) but to trace the value, but the value is always NaN.
<?xml version="1.0" encoding="utf-8"?>
<s:GridItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark" width="100%" height="100%" >[code].......
without the renderer, the column displays the correct values, so apparently the DefaultGridItemRenderer works fine.As requested, here is my Datagrid;
<s:DataGrid id="dataGrid" dataProvider="{_listItems}">
<s:columns>
<s:ArrayList>[code]..........
_listItems is an ArrayList with instances of a model class, which has (amongst others) a property called change of type Number.
I have a DataGrid whose dataProvider is an Array of int Arrays (each with different lengths). Since each row has variable size (and I want to display all the data), I decided to extend DataGridColumn and overwrite the itemToLabel function to be able to display the data. The problem is that I also need to display the data differently depending on the int value.
I believe the only solution is to write an itemRenderer, but the only input the itemRenderer.set(data) function receives is the entire int Array. I believe I need either the exact string returned by itemToLabel or the column index of the cell the itemRenderer is for (to basically do the same parsing I implemented in itemToLabel).
I have two datagrid components and I would like to drag one column from one component to the other. I have been trying several methods but I couldnt acomplish that.
View 1 RepliesHow we restrict datagrid column drag drop...

I'm doing the drag an drop of an ItemRenderer manually (DataGrid) and want to know how to generate a custom DragProxy of a component that hasn't been added to the display list.
I tried something like this but didn't work:
private function doDrag(event:MouseEvent):void
{
var dragSource:DragSource = new DragSource();
[Code].....
So, I want to be able to create the DragProxy using a component, the button is just an example.
I need to allow drag and drop in my DataGrid, but I have a lot of item renderer and item editor that makes conflicts with events when dragging.
So, I want to restrict the activation of drag and drop in the first column ?
I have an AdvancedDataGrid with editable parameter to "true". My problem is that after a successfull drag & drop, the item is being edited and I don't want this to happen. I tried to create a custom advancedDataGrid with this:

View 1 RepliesI have a tree (in Flex 3.5), and I want to use the drag & drop functionality, but I want to let the user only move nodes, not copy them. I tried listening for the dragOver event and change the drag event's action property if it indicates a copy operation, and also listening for the keyDown event and changing the feedback using the DragManager if the pressed key was ctrl, but to no avail.
View 2 RepliesI am unable to find if the spark DataGrid supports moving / reordering the columns. If not what could be the best solution? Maybe using the mx version?
I want the user to be able to drag the columns and arrange them.
I have a data grid where users can drag columns and reposition them. But there is a strange requirement that some columns should not be draged to the left of some other column. eg, assume the columns are: name, price , start date, end date, The end date should not be dragged and placed before the start date. i.e. The user can have start date, price , name , end date. name, start date, price , end date. But at no point can end date appear before start date. Is there a way to do this flex? Is there a way to know where the user is trying to drop the column and show error message ?
