Is there a way to make a Flex 3 Datagrid show only the first node of an arrayCollection, instead of showing all of the arrayCollection's data?[code]...

I am trying to bind an ArrayCollection result coming in from the server to my DataGrid
created dynamically in AS. The result data is not getting Displayed in the Grid.
var dg:DataGrid = new DataGrid();
dg.width=650;
dg.dataProvider=someArrayCollfromServer;
I am adding the dgColumn as runtime based on some data from a XML and it is the same as defined in below static format. But if I use the same code and create the DataGrid as a Flex Component as below, it works fine.
<mx:DataGrid id="dg" width="100%" height="100%" dataProvider="{someArrayCollfromServer}">
<mx:columns>
<mx:DataGridColumn dataField="Value" headerText="Value"/>
<mx:DataGridColumn dataField="Code" headerText="Code" />
</mx:columns>
</mx:DataGrid>
This works fine. Is there some functionality or implementation different as far as DataGrid is concerned in Flex and AS.
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++){

I've got a Flex 3 application with an HTTPService returning an Atom feed. I catch the result from it and store it in an arrayCollection which is then the provider of my Datagrid. I have no problem accessing the data from the "first-level" of my Array, but cannot go under it. Not very clear, so here is some code:
My XML [part of it]:
<entry>
<title>Test 2</title>
<id>http://collaboration.*****.com/collaboration/messaging/feeds/****/todo//7D6637D3E86B3ED3C12575B***8479</id>
<link rel="alternate" href="notes:///C12575B4004***8
[Code]....
The "title" column shows the data correctly, but the status column is empty ! When I launch my app in debug mode, I can see that my notesArray has the correct format and I can access todo -> status with the value..
I've setup my datagrid in flex 3 but, I dont know how to use the arraycollection from my database. How do I place it in my dataprovider?
View 11 RepliesI'm using Flex 4.5 with PHP Zend webservice framework. Basically, I have 2 DataGrids that can drag and drop between each other. At the initializing of the component, I call a webservice to populate the top DataGrid. Then the user can drag rows to the bottom DataGrid that get processed and saved later on. My problem is that I want to have a reset button (or cancel button), that will take the user to a new component in the ViewStack, and if they return to the component with the DataGrids, the top DataGrid has the original records and the bottom DataGrid is empty.
I just can't figure out a good way to repopulate the top DataGrid. I can clear it, but it doesn't seem to refresh with the original data. I've tried unsuccessfully to call the webservice again and set the dataprovider to the new lastResult token. I've also tried unsuccessfully to copy the results of the initial webservice call to an ArrayCollection and simply set a Bindable variable to that ArrayCollection (or a backup of that ArrayCollection holding original records).

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:

here is the code for the set data function (itemRenderer is extending HBox):
override public function set data(value:Object):void {
_data = value;
if(data!=null)

I am creating a Flex3 app to return some results from the Google Geocoding API. I am using the HTTPService Events sample from TourDeFlex as a reference guide to mimic. For now, I have hardcoded the response from Google to use this XML response: [URL] Network Monitor suggests that I am getting a valid response from the XML, but I imagine I have not referenced it correctly for populating my DataGrid?

I'm using FlashBuilder 4 and trying to create a dropdownlist that populates a datagrid. The functionality is fine but my data is being chopped up too much. Currently every since "nepName" tag in my XML file is showing up in my dropdownlist (which makes for many duplicates of the same names) and only shows the data associated with that nepName tag. I want each nepName (by name ex. Barnegat Bay National Estuary Program) to display only once in my dropdownlist and populate my datadgrid with ALL the data in the XML file that is associated with that name

I know that "result" is an ArrayCollection type but i don`t know how to get rows and columns from this. I know that my data is there but i have no idea how to get it.
how to get to Arrays and simple data variables which are in ArrayCollection.
P.S. I tried also change query type in service.PHP for mysql_fetch_query but in that case i`ve got only one row (not all data).

Is it possible to dynamically show row index for DataGrid rows ?
I have a static ArrayCollection which is set to be DataGrid's data provider and I would like to always have row numbering for each populated row (e.g. in a column called "#").
I want show a image onmouse over inside data grid to each row, so if I click on that image, some function should call(as per my requirement).
<mx:DataGrid width="320" height="624" verticalScrollPolicy="on" dataProvider="{blocked_Usernames}" editable="true">

View 1 RepliesIt might sound like a trivial question but how can I show progress bars, when datagrids and other components that "talk" to web services, update their data providers
View 1 RepliesI can successfully add a validator on an item in my datagrid, by passing in the particular element in the dataProvider to the validator, but I can't get the red border to show up around the cell if the validation fails. I have stepped through the validator, and confirmed that it is passing back a failure, but I can't figure out why the red error border doesn't show up. I have a feeling its because I am passing the item in my dataProvider as the validator source, rather than the 'cell' item, but I can't find a way to access the cell.
View 1 RepliesI have made a program in Flex for creating simple schedules, similar to MS Project or Vico Control. I have one problem that I would like to solve. (You can see it here: OnTime Project Scheduling tool made in Flex
The tasks of the schedule are represented as Gantt Chart, for which I created a itemRenderer inside one of the rows in the DataGrid. The tasks are shown as gantt diagrams, but I would also like to show the connectivity between tasks.
take a look at the image below, to see what I am trying to accomplish here: (above is the image of how datagrid looks now, and below is the thing I would like to add)
how I could do this inside DataGrid's item renderer?
Is it possible that when mouse is over the datagrid header the cursor changes to hand cursor instead of the pointer?
View 1 RepliesI have an AdvancedDataGrid with a custom label function whose value can change based on other form status (specifically, there's a drop down to choose the time display format for some columns).Right now, I have this labelFunction:
internal function formatColumnTime(item: Object, column: AdvancedDataGridColumn): String {
var seconds: Number = item[column.dataField];
return timeFormat.selectedItem.labelFunction(seconds);
}
[code]....
... and the timeFormat object is a combo box with items whose labelFunction attributes are formatTimeAsFractions and formatTimeAsInterval.The columns that have time formats have formatColumnTime as their labelFunction value, because extracting the seconds in that function and passing it in to the formatters made for a more testable app (IMHO).
when the timeFormat.selectedItem value changes, I want to force my grid to re-calculate the labels of these colums. What method must I call on it? invalidateProperties() didn't work, so that's out.
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?
I have a data grid where users can drag columns and reposition them. But there is a strange requirement that some columns should not be draged to the left of some other column. eg, assume the columns are: name, price , start date, end date, The end date should not be dragged and placed before the start date. i.e. The user can have start date, price , name , end date. name, start date, price , end date. But at no point can end date appear before start date. Is there a way to do this flex? Is there a way to know where the user is trying to drop the column and show error message ?

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>

How can I make a global varaible ArrayCollection that I can call from differint classes/components in flex?
