Flex :: AdvanceDataGrid Nodes Collapse On Refresh?
Aug 19, 2010
I have an AdvancedDataGrid which Im attemping to update with data from a web service that I poll once very 10 seconds. Im using a HierarchicalData object to provide data to the grid. The update seems to work fine, except that on each update, any nodes that were expanded are collapsed when the grid is refreshed. Stranger still, when I dig down into the bowels of the thing and look at the contents of the HierarchicalCollectionView that backs the grid, I can see that the openNodes property correctly contains the nodes that I opened, but those nodes are not shown as open on the grid...the state seems inconsistent.

I have an advancedatagrid that displays a table of values from an arraycollection coming from a webservice. I am wanting to highlight either the maximum or minimum value in a row or column.I'm not bothered how they are highlighted - be it the backround changed, the font colour changed or just making it bold - I just want that particular cell to be different to the others.What I'm struggling with is finding the cell with the maximum (or minimum) value and then changing it's appearance.In one grid I want to compare across the row, in another accros the columns.

I'd like to add some functionalities to the right border of my ADG component tothe user resize and potentially do more stuff. Is there a skin for that border? For instance, how would you make it wider, or add a handle that perhaps animates when you hover over it?

I have created a tree with a custom treeitemrenderer where I have added a textinput box next to each label. My data provider is an ArrayCollection. When I enter value in the input box, I can see the value fine as I expand or collapse the tree using the disclousure arrow. There is a strange issue when I try to expand and collapse tree from the mxml page with a button click to expand and collapse tree using the following code.
The problem is as I expand or collapse tree, the values I entered in the input boxes appear to be moving.
For example, I have entered 15 in input box 1. When I expand and collapse tree, 15 moves to another input box, and moves to another, and then it moves back to where it was entered as I keep expanding and collapsing the tree. I am still learning Flex. I am not sure what is happening, it is something to do with arraycollection.

I am having some trouble with the flex Tree control.I have a control in my system and of course it is data driven.I have a group which shows a folder icon and that's fine but it also shows an expand icon when the item has no children.I don't what it to show the expand icon when the group has no children but I do want to show the folder icon, because it is different entities in my system.

I develop a piece of code that brings me to an xml, all Nodes i use this code:
for(var i=0; i< menu_xml.childNodes.length; i++){
corrent_node = menu_xml.childNodes[i].length;corrent_item.action = corrent_node.attributes.action;corrent_item.variables = corrent_node.attributes.variables;corrent_item.name.text = corrent_node.attributes.name;
[code]....
What I need is for each of the nodes highlighted in green to return the child Nodes. Example: when I move the mouse over the menu Indoor lighting, the results should be: Indoorlighting | LED 10W> 3W LED> LED 6W

For those unfamiliar with tree structures, tree structures are usually dynamic lists where every node has a pointer to two other nodes. They are arranged so it makes for faster searching and stuff and are very useful in programming languages that offer direct access to heap memory. Although I don't know if there would be benefits of making tree structures in AS would be of any help but I decided to have a go at it anyway. Since there are no pointers in flash I tried to just replace pointers to nodes with nodes themselves. Such things usually work in java I think because the language just automatically makes pointers for variables.

I had an issue with my index.html testing on IE and the preloader just stalls on "loading 0%". he told me that locally the progress event doesn't have time to load and to try uploading it to your server and see if it works. It worked just fine. Rah Rah Kglad.
So today I'm fine tuning the swf/ fla to clean it up. Reduced some picture sizes and deleted unused files and reduced the swf from 4000 KB to 350 KB Rah Rah Gene. replaced the swf in Dreamweaver and re-uploaded with Filezilla. Rah ah Filezilla.
Everything working great and my preload went from 23 seconds to less than 3. So I'm real happy except for one small issue. Firefox and IE both do this. If I hit the refresh button, it stalls on "loading 0%" once again just like it did locally.
If I hit the refresh several times it WILL refresh randomly....2 times refresh......10 times refresh etc.

Spoke to my hosting company who said everything seems fine on the server. BTW he said Chrome did NOT have this issue Rah Rah Chrome.

A web service return to my flex3 client this custom exception:
<SOAP-ENV:Fault xmlns:ro="urn:Gov2gLibrary" xmlns:SOAP-ENV="[URL]" xmlns:xsd="[URL]" xmlns:xsi="[URL]" xmlns:HNS="[URL]" xmlns:SOAP-ENC="[URL]" xmlns:v1="[URL]">
<faultcode>E2gError</faultcode>
<faultstring>abc</faultstring>
<detail><HNS:ROException>
[Code] .....
This is obviously a part of the FaultEvent object I get when the remote call fail, so I'm trying to access "T2gMsg" subnode values like this:
protected function onFaultEvent(e:FaultEvent):void {
var obj:Object = e.fault;
var err:XMLList = obj.element.detail.children()[0].children();
// now I have in err the "Messages" list, subnode of ROException,
// so I should cycle to read one message at time:
for each (var x:XML in err.children()) {
//?
}
How to read ID, Severity etc values. I think something like "x.ID" should work but it's not, while x.child("ID") or x.elements("ID") return null. What can I do?

But that really just gives me back the original XML (since I'm asking for the root where those conditions are met I get the root). I understand why my approach doesn't work, but I don't know where to go from here./grandParent

I am using a Tab Navigator component in which there are three canvas components. When I click one of the canvas (or tab), a Pie Chart is displayed. Actually what happens is that on-click
1. the canvas sends an HTTPService whose url is set to a php file
2. That php file actually gets information from a database. Based on that information an xml file is created
3. Fusion Chart uses that xml file to display a pie chart
The database is being updated after some time. Is there any way the Pie Chart may get updated after every 3 minutes to reflect the modifications in the database? or
Can I send the particular HTTPService again and again after every 3 minutes 'in background'? or
Is there any good way to update the information in a particular canvas (or tab) of Tab Navigator?

How do I get a Flex tree to display only specific XML nodes?
A sample of the XML data is below. Only the Grouper and Product elements should be displayed as branch and leaf nodes respectively; the Name elements should not be displayed. I can't use XSL or e4x to modify the XML as the Name elements' text is used as the label for the Grouper and Product tree nodes. Also, I cannot move the Name element to be an attribute as it needs to include a CDATA section.
It looks like using a custom TreeDataDescriptor is the way forward but I cannot find any examples of using one with XML.
<Grouper Type="ProductHeading" Id="" icon="drugIcon">
<Name>ASPAV</Name>
<Product Id="1002081" icon="genericIcon">

I have a basic Tree built in Flex. The Tree works fine. I'm attempting to get a list of all of the visible nodes. I know there is a Tree.openItems, but that does not suffice because (for example) if you open all the items in your tree and then close the root, the invisible opened items are still counted.

I've got an XML Doc loaded in. I've created an Horizontal List and referenced the arraycollection as the Data Provider. But what I need to do now is then pull the data out from that. I have 3 nodes / variables. They are id, title, thumbnail. But when I go to pull through the data as : {videos.title} Flex Builder gives me the Error - "Access of undefined property videos". Now I know full well it exists, as when I set the dataProvider to {videos} it pulls through the data without issue.
My code is as follows :
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="[URL]"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
minWidth="800" minHeight="600"
[Code] .....
How do I go about getting the XML Node : title and of course the thumbnail too?

on each node, which is end-node ( it is not a parent to anything ) must have a different renderer from the rest of the nodes - a few buttons mostly, arranged vertically. Which means that these end-nodes shall have different height from the rest aswell..
