I have a tree using an ArrayCollection/Object data provider. The following code worked with an XML data provider but won't work with the non-XML data provider:
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?
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 Flex tree with an ArrayCollection as data provider. The ArrayCollection is composed by objects linked eachother by the "children" field (that is an Array containing other children objects)
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'm trying to make a Flex Tree Component display the children of a sprite in a hierarchical way. Moreover, dragging the items on the FlexTree would resort and reparent the items. I have special Elements set as Folders. This would allow other elements to be added there as a children by dragging an element on the tree and dropping it there. I have a failed attempt which works, but breaks when I try to add folders. Basically, it fails at reparenting the items by dragging and resorting folders and that Does anyone know of a component or something which can do this, has anyone have created any of this or could anyone give me a clue?
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.)

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 radio button group within a data grid, whenever I attempt to change the selected radio button the web page crashes. Below is how I put together the radio button in the data grid.
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?*
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 am working on a tree component and I am having a bit of the issue with populating the data-provider for this tree.The data that I get back from my database is a simple array of value objects. Each value object has 2 properties. ObjectID and ParentID. For parents the ParentID is null and for children the ParentID is the ObjectID of the parent.
Essentially the tree should look something like this:
I have a dataProvider and there is an object in the dataProvider. I want to know if there is a way to see if you can check to see if part of the object exists. So lets say I have an object with usernames and passwords and I want to add a username to that dataProvider
I have created a custom item renderer for the tree, i have added some children in create children function, my problem is that sometimes i need to show these children and sometimes i don't, depending on clicking on a button which also i have added at create children, the problem is that i had to create the item even if i don't want it to be visible, and removed it by making visible false, and this costs a lot of memory, i have tried to create it at buttons click listener but when scrolling the child disappears, and it may appear again if i keep scrolling up and down.. i am trying to add the child just when i need it to be visible, is this possible or i have to create it on child creation method?
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();
I have added an event handler for itemOpening event for the tree component inside the handler basically ido myTree.selectedItem = event.item ; and then add the new data inside myTree.selectedItem.children.push(newData); But It do not show simultaneously instead I have to close , open the branch again to see the new data. I think I need to refresh something after adding new data but dont know what? below is the code but without the declaration , script tag etc
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?
That is I want to hide the contact_person and list nodes.Deleting the nodes from the dataprovider cannot be done.So what i did was to create a custom tree data descriptor by extending DefaultDataDescriptor.Then override the getChildren method and applied a filterfunction to the collection returned by super.getChildren.The problem is when i hide the 'list' node I cannot have the child nodes to show up.So is there any way I can hide 'list' but show the children of 'node'?
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 viewstack with childrens which I want to show/hide depending on the state the application is
[Code]...
AS you can see I inlude the retail customer view in the retail state and the wholesale customer view in the wholesale state. The problem is that when I run my app they don't appear on neither state.
In flex 3 I have a hierarchical data structure. I would like to display the content of it in a tree. My problem is that I have nodes which data calculated from children nodes. How to structure the hierarchy to make automatic changes to those parent nodes, if their children's data changed? For example:
Every node has a warning flag. If some of the children warning flag changed to true, then the parent warning flag should change automatically set to true. A node integer field is the sum of the children integer fields, and if any of the children changes, the parent integer field "calculates" the sum immediately. Is there an easy solution wit good structuring changes happen automatically, or I have to make some custom functions?
I have a container symbol called BoxContainer. This can contain an unknown number of Radio Button components. To add these, I have an array of Radio Buttons called boxes.This is part of the CheckBoxes class.Here's my problem: When I add the radio buttons as children to the stage, from the frame itself, it works just fine. However, I need to add it to the BoxContainer movie clip. I have tried:
On the frame: for(var i in Checkbox.boxes) {[code]..........
However, both of these do not work. When I run the flash, the radio buttons are not visible. How can I fix this?
For instance the mx.controls.Image objects are only displayed when i add them directly to the main application object. If i add a "subimage" to the previously created Image object it simply doesnt show.
What I want to do:
var img : Image = new Image; var subimg : Image = new Image; img.source = "images/panel.png";
