Flex :: ArrayCollection - Selecting Value From ComboBox
Sep 22, 2010
My goal is to create a generic function that selects a value in a combobox according to a value. (My comoBox holds arrayCollection as dataProvider.) The difficulty is infact to get a propertyname in runtime mode.
public function selectComboByLabel(combo:ComboBox , propetryName:String, value:String):void {
var dp:ArrayCollection = combo.dataProvider as ArrayCollection;
for (var i:int=0;i<dp.length;i++) {
if (dp.getItemAt(i).propertyName==value) {
combo.selectedIndex = i;
return;
}}}
The line if (dp.getItemAt(i).propertyName==value) is of course incorrect.
It should be arther something like: dp.getItemAt(i).getPropertyByName(propertyName)

I use this arrayCollection to populate a Flex 3 Datagrid. I'd also like to use this arrayCollection to populate a comboBox with the Name node.
In the arrayCollection, I've got the Name listed twice. I've got two rows in the Datagrid.
If I set the ComboBox's labelfield to Name, then the Name will be listed twice in the ComboBox menu. Is there a way to use this arrayCollection and have each Name listed only once in the comboBox?
I can always make another loop and array collection for the Name, but I was wondering if there were a better way.
var i:uint;
for (i=0; i<myArray.length; i++){
myDGArray = [

My first issue is that when my ArrayCollection only has one item, for some reason I cannot select that first item. The change function set on the mxml never gets called when I try to select that one item. If I set a prompt, it works. I know that the item is not already selected because when debugging, the selected item shows null. I do not want to use a prompt. I want the first item in the ArrayCollection to be selected automatically. So if there is only one item, I want the selected item to be that. FYI - I am using a labelFunction to format the data in the Array Collection. why I cannot select the first item or set the first item in the ArrayCollection to be the selected item?
My bigger issue is that when my Array Collection gets updated, my label function must not be refreshing because when I first open the dropdown, it has specfic data. When the Array Collection gets updated and I open the dropdown again, I see the old data in the dropdown, yet it doesn't exist anymore.
So let's say I have a ComboBox that has a datasource of an array collection of one state code and it's state name. Their is a labelFunction that puts a dash in between the state code and the state name. Their is no prompt, so the ComboBox would look like GA - Georgia and when you open the dropdown, that would be all that is there. I want that item to be selected automatically. why the old data shows up when opening the dropdown after the array collection was updated with new data?
<mx:ComboBox labelFunction="getFormattedNpaNxxCollectionList()"
dataProvider="arrayColl" change="doSomething()"/>
public function getFormattedNpaNxxCollectionList(item:Object):String
{
return StringUtil.substitute("{0} - {1}", item.stateCode, item.stateName);
}

I am developing a panel in Photoshop with Flex and Extendscript. I am pretty close to getting this to work, but with my Flex skills I am having a little issue with the Array I am pulling in from the jsx file. The array is displayed fine in the alert box, but somewhere between my split and creating new collection something is wrong.
Here is my Flex
protected function loadData():void {
var grabFolderNames:SyncRequestResult = CSXSInterface.instance.evalScript("labNames");
var list:String = grabFolderNames.data;

Is there a way to reverse the order of the items in a comboBox? I'd like to use index numbers to refer to items in the arrayCollection below. I want the newest content to appear first in the comboBox. But, if I add something above the first item then all of the index numbers will be off by one. If I could add a new item to the end of the arrayCollection, but have it appear first in the comboBox drop down that would solve a lot of problems.

I'm using a combobox component that I'm populating with a five-element array, as follows:
0 All
1 Bakery
2 Diary
3 Deli
4 Drink
And because I don't want "All" displaying in the text box, I've added the line
dropDown.text = "Select here..."
once the combobox is populated. Unfortunately, when I test the combobox and open the list, "All" is at the top of the list but already selected, so that when I click it, nothing happens. The rest of the items work fine.
Could someone tell me how to disable the first item, so that it's not automatically selected when the list opens and therefore can be clicked?

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>

I'm trying to set a specific list item in a mx combobox to have a custom item renderer, the problem is that I cannot do this via mxml, it needs to be done via actionscript at a later stage, eg: combobox gets created, combobox gets populated, user does other tasks, combobox needs to set one or more items in the combobox to have icons (via item renderer)..
I can do this via the onChange event, but it only applies the icon when the combobox is opened and there is a slight delay so you can see the icon being added.

I have a flex mobile application that I am working on that I am having issues with selecting an image from roll/taking a picture. My application is not tabbed, however one part of it contains a Tabbed View Navigator with tabs across the bottom. Within one of those tabs, I have the ability to upload an image to a webservice that I have created. However, when I select an image or take the picture, it pops back out to the initial splash screen and the application restarts. If I use the component standalone (outside of the tabbed view navigator) it selects the image and uploads without any problem.

I've created an Flex app. It currently has an drop down menu. With the option to select a Channel. Once the channel is selected the data pulls through. But, what I want to do is just pull through one channel of data as opposed to multiple items of data. How can I achieve this?
My code is quite simple at the moment and looks like this :
<mx:FormItem label="Select your Channel : " x="296" y="0">
<s:DropDownList id="channelSelection"
dataProvider="{channelList.lastResult.channels.channel}"

I have a datagrid with 5 columns. The first column has checkboxs and rest four columns have data from the dataProvider.
I have two relating issues: First: I want the row to get selected when I click on a checkbox, or if i click on multiple checkboxes, every row should stay selected in the datagrid for whose checkbox is selected.
Second: If a row or multiple rows are selected, the corresponding checkbox should get selected too.
My code is given below:
<mx:DataGrid id="dg_trashContent" allowMultipleSelection="true"
verticalGridLines="true"
dataProvider="{trashDataProvider}"

I have posted two problems with a custom itemRenderer see this post. My primary Problem is, that it always selects a wrong line (one under the one I select). I now realized that this happens, when I save back the content of the itemRenderer to the dataProvider. If I code this part out, the dataGrid works as expected...

I'm having a problem displaying data from a function to text box within a tab. If you run the code and click "Select Tab 2 and Fill..." I get an error; "TypeError: Error #1009: Cannot access a property or method of a null object reference." I'm guessing this is because "Tab 2" is/was not rendered yet. Now if I run the code, select "Tab 2" then select "Tab 1" and click "Select Tab 2 and Fill..." it works the way I would like. Dose any one know a way around this problem.

Output: texta textb Now I want to select from "ta" in TextField1 to "tex" in TextField2. By the drag of a mouse. I know that by conventional methods it is not possible? Is there any other way to achieve this? And I need to highlight the text also.

i have a problem using the itemRenderer functionality. When using an ArrayCollection the visible Data in the DataGrid using the itemRenderer will be rendered just fine. But if i start scrolling the entries are repeating in the cells using the renderer. The cells are not filled with date according to the id. What mistake i'm doing here.
I read a lot of the explainations like:

Inside a datagrid, I essentially want to create a "download button" itemrenderer to the right of the name of a downloadable object, resulting in something like the following link: [URL]
The download function operates upon the currently selected row and is called when one of the download buttons is clicked. Therefore, I am wondering if anybody knows of a way to select the row the itemrenderer button is contained within as the active row when one of the download buttons is clicked.

I have an array of items that should be selected in my tree control. As you can see from my code below, I bind this array to the selectedIndices property of the tree. The selected Items are not properly selecting in tree(selecting some other items and always root is selected).Flex seems to "ignore" my items (selects some other indices).
My XMLList:-
<fx:Declarations>
<!-- Place non-visual elements (e.g., services, value objects) here -->
<fx:XMLList id="XMLList">
<node><node name="max">

the applicable differences between an ArrayCollection and a Vector in flex? I'm unsure if I should be using one over the other. I saw that Vector is type safe and that makes me feel better, but are there disadvantages?
public var ac:ArrayCollection = new ArrayCollection();
versus
public var vec:Vector.<String> = new Vector.<String>();

In Flex, it's easy to convert the XML to Object and to ArrayCollection by using var decoder:SimpleXMLDecoder = new SimpleXMLDecoder(); decoder.decodeXML( xml );
But is there a good way to convert ArrayCollection to XML.
