Flex :: Conditional Data Provider To Tree On The Basis Of List Selection?
Aug 1, 2011
This is my XML data in a file named nodesAndStuff.xml.
<?xml version="1.0" encoding="utf-8"?>
<root>
<node label="One" />[code].........
Now I have added my tree just below the list and I have saved counting from 10 to 19 in one.xml, 20 to 29 in two.xml and so on in different XML file. I have no clue how to connect the XML containing counting from 10 to 19 as the single node in tree at the selection of label one in list

I have a requirement to filter the tree similar to that of flex builder-->preferences wizard tree.
My tree dataprovider is arraycollection of industries. Each industry has a list of sub industries and further, say upto depth 5.
So when we type in a string to filter, only the node having this string along with their parent hierarchy should be returned.
How can we implement this using flex?

I have a Flex tree with an ArrayCollection as data provider. The collection holds an array of CategoryVO objects. Each object can have another array of CategoryVO objects inside it's "child" attribute. This way the tree displays the data correctly. Now I want to get the parent of a specific item, e.g. tree.selectedItem. Using XML as data provider the item parent is avaiable thorugh the parent() method. But I can't convert my data to XML. How can I get an item's parent? Perphaps using the tree's dataDescriptor?

I have a situation where I have a List showing a queue of Upload Objects:
[Code]...
I would like to create three different views of the List: One showing All uploads in the queue Another showing only the Upload items with Upload.type == "Update" and another showing only the items with Upload.type == "Create". Another example of this would be on an email inbox, where we could filter "All, unread, or read". I realise I could just create three different lists, one for each view of the list (maybe I'm just being picky) but I was wondering: Is there is any easy way to conditionally select the items to display from a DataProvider based on a parameter (for example type =="Upload") so I don't have to juggle three separate ArrayCollections about?

I have been trying to populate a tree control via an httpservice that uses php to talk to a database. The queries work fine and the data comes back in the following format from php:
echo "<root>";
echo "<topic>";
echo "<sectioncode>$sectioncode</sectioncode>";
echo "<children>";
echo "<labtitle>$title</labtitle>";
echo "</children>";
echo "</lab>";
echo "</root>";
Flex can see this and interprets the heirarchy fine unless i try to format the resultformat in the httpservce (if i do that it goes a little nuts). The results from the php query to the db come back as an ArrayCollection with each containing a "root->topic->sectioncode->title" type of structure (which is what I want). When I go and try to use this Arraycollection as a dataprovider for a tree control, it doesn't work at all. When I use the arraycollection as the dataprovider I get [object,object] for every row in the tree and there is no parent/child structure.
Ideally I would like the title to be a child of the numbercode, but when i try and format the return from xml like that the number becomes and object without a value and the title becomes a child. I have a feeling that I am missing something in the php return to show the structure to flex more clearly and also something in the tree to implement it as the data provider better. Here is the code that I am using in the tree:
<mx:Tree x="25" y="48" height="451" id="ilabtree" dataProvider="{labarray}" labelField="@title" width="152" textAlign="center"></mx:Tree>

I am having trouble searching through a list component and/or dataprovider to see if an item already exists. Basically i am adding items to the list when a item is dragged on to the list. But i want to check to see if an item is already added so not to duplicate items. any ideas would be great.

I am currently working with a hierarchical tree structure in AS3/Flex, and want to enable drag and drop capabilities under certain conditions: Only parent/top level nodes can be moved Parent/top level nodes must remain at this level; they can not be moved to child nodes of other parent nodes Using the dragEnter event of the tree, I am able to handle condition 1 easily.

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 a tree in Flex Application and one of the items is selected.
When a user clicks another item, I would like to make a check and possibly prevent the change of selection.
I tried catching click event and calling stopPropagation, and also itemClick with stopPropogation but both do not prevent selectedItem from changing.[code]...

I want to display the same data in a chart and a data grid. I want to use the same data provider for both of them to reduce the amount of SQL queries.How do I transform the database structure into the chart structure and into the table structure using ActionScript?*
Database structure in JSON format:
[
{key:, year:, value:},
{key:, year:, value:}
]
Data provider structure required by a chart:
[
{series1:, series2:, year:},
{series1:, series2:, year:}
]
Data provider structure required by data grid:
[
{key:, year2000:, year2001:, ...},
{key:, year2000:, year2001:, ...}

I have a datagrid that uses an array of objects as the data provider. The objects are essentially key/value pairs:
{ foo:"something"}
{ bar:"hello"}
{ caca:"lorem"}
The datagrid has 2 columns. The first column is the key and the second column is the value. Right now my grid looks like:
My dataFormatter function makes sure that depending on the column (i.e. the dataField value) the correct key or value gets printed out. This works fine for displaying. However, as soon as I try and edit the value field it essentially adds a new value into the object with a key of '1'. For example, if I edit the {caca:"lorem"} object it will then contain the value {caca:"lorem",1:"new value"}.
Is there any possible way I can set the DataGridColumn so that when I edit a value it will update the value associated with the key rather than inserting a new value? I've tried using a custom item editor but it still does the insert. It seems like I need to be able to update the 'dataField' with the actual key value but I'm not sure how to do that.

i get this error when i retrieve an XML that only has 1 node (no repeating nodes) and i try to store in an ArrayCollection. -When I have MORE than 1 "name" nodes...i do NOT get an error. My test show that XMLListCollection does NOT work either.
TypeError: Error #1034: Type Coercion failed: cannot convert "XXXXXX" to mx.collections.ArrayCollection.
this error occurs as the line of code:
myList= e.result.list.name;
Why can't ArrayCollection work with a single node? I'm using this ArrayCollection as a dataprovider for a Component -is there an alternative I can use that will take BOTH single and repeating nodes as well as work as a dataprovider?
code:
[Bindable]
private var myList:ArrayCollection= new ArrayCollection();
private function getList(e:Event):void{
var getStudyLoungesService:HTTPService = new HTTPService();

How do I differentiate between a data provider update and a itemrender being recycled when using a custom itemrenderer in a DataGroup?I have overridden the set data function of the custom item renderer, but I have found that on making a change to the ArrayCollection used as the DataProvider some of the item renderers are not assigned the same object they had before the update. This has made it almost impossible for me to distinguish between a data update and an itemrender being recycled. Also, the data never seems to get set to a value = null, so that seems to be out as well.

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 want to create a custom list in Flex for an interface prototype. The list is supposed to have an image and 3 text fields. This is what I have done so far, the control displayed is what I want. But, when I click on one of the items, the item does not appear (visually) to be selected. I was not sure how I would implement this.
Here is my code so far:
<s:List width="400" height="220"
dataProvider="{arrColl}"
alternatingItemColors="[#EEEEEE, white]">

//Where myDataArray is an ArrayCollection consisting of my Custom ValueObjects. When i execute the code it displays my list with custom item renderer, which is fine. But when bring my mouse over it, it doesn't give any colour highlight which means it is not selecting. Secondly, when i click on any of the list item, it doesn't dispatch any change event. I tried a lot but couldn't understand it.

I have an issue with Spark Lists whereby I am trying to ensure that an item is always selected and ensure that the GUI displays this to the user.
The application (full code below) creates a List, a Label and a Button. The Label states what is selected in the List. The button removes the selected item. Changing the selection, updates the text in the Label. Important: The List has "requireSelection" set to true to ensure that an item is always selected.
If I select the first item in the List, the selection is correctly reflected in the label. Clicking "Remove" removes the item and the next item is selected. This is all working correctly.[code]...
