Flex :: Mxml - Components Bound To Empty ArrayCollection At Load Time Don't Render As Expected When The ArrayCollection Is Updated?

Oct 27, 2009

I'm new to Flex and am using TileList bound to an ArrayCollection. The array collection is empty at load time, and then updates with the results from am HTTPService call. The problem is that the item renderers aren't being rendered as expected, I'm guessing because there was no data when they were first rendered at load time. Here's simplified example:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" >
<mx:Script>

Flex :: Make Changes To An ArrayCollection Bound To Data Grid Live?

Feb 21, 2010

I have an ArrayCollection bound to an editable DataGrid, another component needs to know when the ArrayCollection changes (as a result of changes in the DataGrid) so it can also update itself, so is listening to the COLLECTION_CHANGE event of the ArrayCollection.

The problem is that the DataGrid only updates the ArrayCollection when the row being edited losses focus. This is not good for my app as a user could edit a column on a row and not click elsewhere on the table for a long time (causing the row to lose fucus), therefore the changes won't have propagated to the other parts of the application.

How can I make the data grid inform the ArrayCollection of a change every time there is a keyup event on a text input instead of every time a row looses focus?

Flex :: Display ArrayCollection In Group With An Item Render?

Jul 27, 2011

i got an Arraycollection which holds other arrays in it.i want to display the data inside with an item render but cant manage to do this
here is example code to explain my question

<s:DataGroup dataProvider="{news}"
itemRenderer="components.displaynews">

and this is the item render

<s:Label text="{data.??/}"/>

now what i dont understand is what comes after data? in the array collection the data goes like this : myArrayCollection->[0]->firstname

so when im binding data to item render,how do i represent the [x] to get to the specific name that i want? this obviusly wont work

<s:Label text="{data.[0].name/}"/>

and one more thing is what is the lightest way to display data in a listgroup with simple item render (image and text)

private function convertFBEventData2TreeData(eventData:Object):Object
{
var children:ArrayCollection = new ArrayCollection();[code].....

i dont know what to add after data, i tried many things but nothing work :

Actionscript 3 :: Make AdvancedDataGridRenderProviderer Render An ArrayCollection?

Nov 23, 2011

I have an object that looks like this:

[Bindable]
public class MyRecord implements ValueObject
{[code]...........

In this renderProvider I override the set data function to set the dataProvider:

override public function set data(value:Object):void
{
If using the array data source, use this instead:[code]......

The problem is that my renderProvider's method is invoked for every record in the dataProvider of the ADG it is part of. This amounts to a brand new DataGrid for each trade in groupedTrades.

UPDATE: I just found some hardcoded array from a blog that is doing what I want; a DataGrid as a renderProvider of an AdvancedDataGrid.

private var masterData:Array = [
{ OrderId: 10248, CustomerId:"WILMK", EmployeeId:5, OrderDate:"1-Feb-2007",
children:[[code]....

I fail to see the difference between the hardcoded version from the blog that works and the data I'm using from my service. What am I missing?

[1] - name: hello
[2] - name: hello1
[3] - name:hai

Arraycollection:-

Flex :: ArrayCollection Fast Filtering (one Chart At A Time Is Not Option)

Sep 19, 2011

I have the following situation: have a screen with 4 charts, each being populated with 59 array collections. Each array collection has 2000+ data points. This construct needs to be filtered(by time), but the problem I'm encountering is the fact that it takes a long time for the filtering to finish (which is to expected given the amount of data points that need to filtered).

Filtering one chart at a time is not option, so I wanted to ask you what do you think would be the best approach? (should I use vector instead?). To generalize this question what would be the best way to filter large collections in flex/as3?

Php :: Zend_AMF: Get A ArrayCollection From Flex?

Sep 22, 2009

I currently have an arrayCollection in Flex and I want to sent it to PHP (Zend_AMF). According to the Zend_AMF wiki, sending an arrayCollection over directly will force Zend_AMF to cast the arrayCollection as an object which is no good. I'd rather have an array of my models. I assume the best way would be to convert the arrayCollection to an array in flex and then send it over. Is this true, and if so how would I do that in Flex 3? If you have a better recommendation,

Flex :: How To Get Memory Size Of ArrayCollection

Feb 2, 2010

I have built an image cache which is an ArrayCollection containing images. I have built functionality so that the cache can hold a max of 250 images. However, the images can be of a different size, so it's better to limit the total memory size of all images in the ArrayCollection. How I can get the total memory size of an ArrayCollection without looping through all the items in the ArrayCollection?

Flex :: AdvancedDataGridRendererProvider ChildrenField ArrayCollection?

Feb 5, 2010

I have a main class ClassA that has a bunch of "normal" properties that are simple datatype like ints, strings, etc. It also has one property ("childItems") that is an ArrayCollection of ClassB.I am using an ArrayCollection of ClassA as the source for an hierarchical data provider for an AdvancedDataGrid. I set the childrenField to "childItems".

I want to display some information about the list of ClassB objects in a nested table and pie chart, an AdvancedDataGridItemRendererProvider (columnIndex = 0, columnSpan = 0, depth = 2) and point it to my custom renderer which is an HBox with the table and the pie chart in it.

In order to see what is being set, I override the "set data" function in my custom renderer and what I see is that each instance of ClassB in the ArrayCollection is passed to the renderer separately.

Here is my question: I expected the whole ArrayCollection of ClassB instances to be passed to the custom renderprovider once and not each item in the child list individually. How do I make the ADG understand that the whole property is supposed to be passed as the data to the renderer and not each entry separately? Btw, when I change the data type of "childItems" from ArrayCollection to ArrayList, the whole list gets passed and I can easily do what I want to do. But based on my understanding, ArrayList is not really supposed to be used and ArrayCollection is better or at least more common.

Flex :: Getting Unique Elements From An ArrayCollection?

Mar 19, 2010

I have an ArrayCollection as mentioned below.

private var initDG:ArrayCollection = new ArrayCollection([

I want to populate a ComboBox with UNIQUE VALUES of "appName" field from the ArrayCollection initDG.

<mx:ComboBox id="appCombo" dataProvider="{initDG}" labelField="appName"/>

One method I could think is to loop through the Array objects and for each object check and push unique appName entries into another Array. Is there any better solution available?

Flex :: Binding Applies Only To One ArrayCollection?

Apr 15, 2010

I have a datagrid that gets its data from a webservice.When data from the webservice is retrived it calls the following function:

private function onListReg():void
{
arrRegOld = WSAutoreg.list.lastResult as ArrayCollection;
arrReg = WSAutoreg.list.lastResult as ArrayCollection;

[code].....

The intent is when I hit a update button, it compares arrRegOld with arrReg and see if any values have changes. The problem is whenever I change values on the Datagrid it changes on both the dataProvider and on both ArrayCollections.What should I do so that the binding applies only to one ArrayCollection?

Flex :: Binding To Arraycollection Does Not Work?

May 23, 2010

I am using flex SDK 3.5. I have model.as and in it i have an ArrayCollection (name it arr_mod) which is Bindable.

From my mxml i link to this arr_mod in three places:
1) in DataGrid i set dataprovider={arr_mode} ...

2) in Button i add new item to the arr_mod this way: mx:Button .. click = "{arr_mod.addItem(new Item)}"

3) in textBox i want to add mx:TextBox text="{mySpecialCounterFunc(arr_mod)}"
note that in the Script of mxml arr_mod is Bindable as well as in the class definition in model.as

The problem is, that when clicking on button, mySpecialCounterFunc is not called! it should be called, since i use {} and this should listen to changes in arr_mod (a change that was made in the button should cause a new item to be added.. and than the listener to respond). While The DataGrid is updated correctly! By the way, if i change arr_mod to simple String or Int it works.. i.e. mySpecialCounterFunc is called Why??
