How to populate a flex datagrid from an Arraycollection without specifying DataGridColumn's individually. Is there any custom datagrid available where I can pass the datasource arraycollection and see the data populated in the output. Without knowing the structure / bluprint of an object is there anyway to find how many member variable that class have?

I have an actionscript class with a static member variable defined.
public class A
{
public static var x:int;
}
When I try to access it from different parts in my code I don't get the same value in each spot.
A.x
I am accessing the variable in different modules that are loaded, so they are all in their own separate .swf file.
I am trying to figure out how to manage a Datagrid based on an XML object like this:
[Code]...
I will need to populate the Datagrid column names based on a different XML object and use the above XML to populate each of the column's rows. I currently am able to create the Datagrid and populate its column headers but I am unsure as to how to how to add the rows for each column. The above XML will be update with new row and column elements added and deleted. This, of course, will be bound to the Datagrid to show updates.
How can I access the member variable of an object by using a variable in the name.Example:
Entries Object has properties 1, 2, 3, 4, 5.
Normally I would access them by
var i : int = Entries.1;
[code].....
I know the problem has something to do with the string vs number issue and I've tried a few things, but can't figure it out.
var HDLrange:int="enterRange_txt.text";
enterRange_btn.addEventListener(MouseEvent.CLICK, onClick);
function onClick(event:MouseEvent):void[code].....
I have flex advancedDataGrid (could use dataGrid if that works better, though i like my meta-column headers), and i want to have a component popup on top of a selected row.
The problem is, i can figure out how to reference an actual rendered row of a datagrid (rather than an item of the dataprovider) in order to get its position on the screen.
how to access a "row" of a datagrid, or at least get its position?
I am unable to bind the selectedIndex public property of a spark DropDownList to it's original source in the view's presentation model.
For the purposes of replicating this issue with as few lines as possible I have two views, and one presentation model. The code follows.
Main.mxml
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
[code]...
Debugging the application I find that selectedIndex in the presentation model always remains at the default value assigned regardless of which item I selected from the DropDownList. For the sample code above this is -1.How can I bind the selectedIndex in the presentation model such that it is updated appropriately when the selected item DropDownList changes?
I created an flv video player using Flash Builder 4. This "BasicVideoPlayer" project is compiled into a SWC that will be eventually be used to create other video players that extend the functionality. One of the features is a view that appears when the video has finished playing that displays a "Play Again" button. This "Play Again" view has its own class, "BasicPlayAgain", that accepts a graphic asset that is exported from a .fla file that contains all of the graphic/UI assets.
In my new project, "EnhancedVideoPlayer", I'm using the BasicVideoPlayer SWC as a library to create a new video player that will add more functionality to the "Play Again" view; specifically it will add more buttons to that view.The EnhancedVideoPlayer uses a default class that extends the BasicVideoPlayer class. The BasicVideoPlayer class has a member called "playAgainScreen" whose type is BasicPlayAgain. The EnhancedVideoPlayer needs to override the playAgain member and recast it as EnhancedPlayAgain so it can control the new buttons properly.
I have a class, call it MyClass, and there are several variables that I need to be able to access each instance of from within the class.So for instance, I need the object myObject1, a member of MyClass, to store the variable myNumber.From the main timeline, if I trace myObject1.myNumber, I get whatever number I've stored.
However, I need to check the numbers against another parameter, so I need to be able to test if myObject.myNumber == myOtherNumber. But from within the class, if I trace this.myNumber or myNumber I get null.What is the proper syntax for accessing a variable within a class?

I'm trying to do something with eventListeners, but i still do a lot of messy code, so wanted help of those who already know flex.
I'm have a DataGrid, and its itens are added by another component, no problems with that.
I have buttons to Add, Remove and Edit the items inside the DataGrid. No problem with that too.
But i want those button to be enabled when the DataGrid as at least one item, and when it doesn't as any, all three buttons should be disabled.
EDIT: Forgot to say: I think eventListeners are the best way.

View 4 Repliesrecently, I research for the collection framework, and find LinkedSet(AS3Commons collection framework,it is a good opensource framework) written in ActionScript, but it can't use as dataProvider in ComboBox or DataGrid, because only implements ICollectionView can use as dataProvider. So I want to try if a class implements ICollectionView can work or not. I know Flex has build-in class implements ICollectionView, but I only want to define a class not use build-in class. The class as simple as possible.(can work is enough)

View 3 RepliesI know that one can give a symbol already placed in the scene and instance name and be able to manipulate that object programatically through ActionScript in Frame actions. What I want to do instead, is bind that instance name to a class member so I can use it inside a class file and and eliminate the need for frame scripting.
I am new at this and I'm trying really hard to figure out what the ideal workflow is. I would like to use a fully OOP approach at developing my applications, however I like to use the graphical interface to position assets on the scene because I find it easier than positioning assets programatically. So the solution I am looking for is binding assets to class members. If such a workflow is not possible, what's the best approach in dealing with assets in a fully OOP design?
Why does Flex 3 DataGrid read a string from XML lastResult.node as number?A field is saved as var_char in mysql, php reads it as string and pass it OK.If there are more then 16 charaters it gets rounded....For example:
this in database cell:
12345678901234567
gets read in DataGrid as nubmer as 12345678901234568
this is in database cell:
5555544444222223333377777
php reads it same and puts it in XML flex reads XML into arrayCollection and DataGrid reads it as:
5.55554444422222e+24
So it reads it as number, why? And how to make it read as String? I tried with labelFunction, no help.

View 1 RepliesI'm trying to set up a menu. Because this menu can have a varying number of entries, I'm generating it instead of hard-coding it. The Menu object contains an Array of MenuEntry objects, and each MenuEntry has a framework.Button object which contains the text and box that actually gets drawn to the screen. I can add a MouseEvent.Click event to the Button, but not the MenuEntry. If I do it that way, though, I'm unable to access the data in the MenuEntry object that contains the button, so I don't know which MenuEntry was clicked.
The only solution I can think of involves checking the mouse position against the position of each MenuEntry, depending on the number of Menu Entries. This does not seem like the right way to do it, though, as it is not scalable. I tried having the MenuEntry class extend the Button class, so theoretically, the MenuEntry itself could dispatch mouse click events, but that didn't work.
I'm binding an array of items to a data grid using ItemRenderer. I use the data variable to control the bindable data. I also have someComponentVariable that need be inserted into every row but its declared at the component scope, so the data grid doesn't seem to reconize it (compile error). How can I use this variable (someComponentVariable) inside the ItemRenderer?

i am creating a popup of a textarea though which i am storing my notes in a data grid. The Code for the data grid is given below.
Now when i add the note IT fits in one of the rows. Now all the rows have same size. I want to make the size variable so that the text fits in each row. For big text notes the height of rows should be greater so that no scroll needed. similarly when the data is small then the height should be small

As the View is presented as a static and not a variable. When you try to submit it as a variable in any format (String, Object) an error occurs.

how I can send the (View)Class as a variable or if this is a bug in the SDK
