Datagrid with textfield problem

Hello,
I have a datagrid with a custom cellrenderer that renders the datagrid column as a textfield. This works fine, but when I scroll the datagrid up and down, the text in the text field gets all jumbled. I have attached an image showing before and after scrolling. I am assuming that I need to redraw the datagrid after the scrollbar loses focus or something like that, but I am new to AS3 and unsure how to proceed. Any help greatly appreciated!

The phone can deal with that. It's just how the input system of most phones work: a sentence starts with a captical letter. you can simply turn that of, just as you would so if you were writing an sms. See your phones manual for that!

Editable Datagrid with LabelFunction Problems

Hi,
I'm having problems with a datagrid with editable columns and labelFunctions.
The problem is that when i leave the editable field by a way that wasnt with Escape Key, the datagrid apply again the labelFunction and destroy the number formattion adding a lot of numbers.
When the field is filled with 0000,00 he just adds more zeros, like 0.000.000,0000 and keep going after do the same process.
And when the field has a number different of zero, he apply the labelFunction then after he remove the labelFunction. After few times it just make the number vanish and the cell goes empty.
I read the documentation about editing cell and tryed to implement a solution to prevent the cell be edited, without sucess.
The source code goes attached for some advice on my problem.
Thanks, Fredy.

Hi,
I solved a part of problem with some changes that i've made.
Now there is no problem with values different of zero, when i got just number, its fine, but still have problems with zero values.
The snippet code goes next, the bold part that was modified from the last sample.

@Alex
Thanks for the answer.
I want to edit this column, but if there is no 'change' i dont want to apply again the label function and close the itemEditor.
I've tryed to call event.preventDefault() but i dont know what to do next.
Do you have some advice how to solve my problem?
This is just happening when i got zero values on my datagrid =/
Thanks all for the answers.

Problem filling DataGrid with XML - Object or ArrayCollection?

Hi,
I am trying to fill a datagrid with an XML file, rendered
from a PHP
script.
The problem is that - first time there is only one entry in
the XML
file, so when I receive the data using
event.result.root.child, I get
an Object. But second time, when there are two entries in the
XML
file, the return type becomes an ArrayCollection of "child"
type
objects.
This causes a problem when setting dataprovider of a
DataGrid....
So is there a way I can know what is the return type from the
XML
file, i.e., whether it is an Object or an ArrayCollection, so
that I
can set the dataprovider accordingly?

In E4x
If you have an xml structure like so:
<parent prop1='someValue' >
<child prop1='someValue' />
</parent>
to reference the parent use event.result
to get the child use: event.result.child; to get the child
attr: event.result.child.@prop1;

Need for a Datagrid with variableRowHeight="true" and custom Item Renderer to display exact rows

Hi again, developers:
I'm in a search of a datagrid with certain characteristics:
     - variableRowHeight = "true"
     - only one column
     - each row must have a custom item renderer with possibly different heights, and a fixed width
     - the datagrid must show always every item in the data provider with no vertical scroll bars, what means that the datagrid height must have always the exact height sum of all the item renderers it is displaying.
     - and no extra empty rows must appear in the last positions of the datagrid
The last two requirements are something difficult to achieve... for some reason, empty rows appear at the last positions of the datagrid. I post what i've managed to get:
<mx:Script>
     <![CDATA[
     private function resize():void
                if (dg.dataProvider)
                    var h:Number = dg.measureHeightOfItems( -1, dg.dataProvider.length);
                    dg.height = h;

            </mx:DataGridColumn>
        </mx:columns>
    </mx:DataGrid>

Thanks Harui, but it doesn't help. If the border is set it will help, but the very big problem is the empty rows that appear at the end of the datagrid... I can't find a way of measuring correctly the height of the itemRenderers!
I'll update this thread if I manage to do it.

Strange Behaviour on DataGrid with ArrayCollection as DataProvider

I have a Datagrid with an ArrayCollection as DataProvider, the arrayCollection is partially generated by a remoteObject call, the dataprovider seems to works at least until I try to edit the field...
By the RemoteObject I only receive an ArrayCollection with the field `ip`, but the datagrid looks for the fields ip, check and save...
If I add/edit this new field it works, but only under particular condition
The DataGrid:
<s:DataGrid id="datagrid" left="10" right="10" top="136"
       dataProvider="{listaIPCheck}" bottom="10" requestedRowCount="4">
          <s:columns>
                <s:ArrayList>
                     <s:GridColumn dataField="ip" headerText="Asset"/>
                     <s:GridColumn dataField="check" headerText="Inventory"/>
                     <s:GridColumn dataField="save" headerText="Salvataggio"/>
                </s:ArrayList>
           </s:columns>
</s:DataGrid>
The Script:
   [Bindable]private var listaIPCheck:ArrayCollection;
    private function ro_resultHandler(event:Event=null):void
      listaIPCheck = new ArrayCollection();
      listaIPCheck = ro.getListUpdate.lastResult;
      heap = 0;
      // Read Below {POINT #1}
      init3();
    private function init3():void
     // Read Below {POINT #2}
     if (heap<listaIPCheck.length)
        // omitted the initialization of the process p
        p.addEventListener(NativeProcessExitEvent.EXIT, onExit);
        try{
          p.start(startupInfo);
        }catch(e:Error){}
    private function onExit(e:NativeProcessExitEvent):void {
        // Read below {POINT #3}
Here is my code, now as you can see there are 3 line where I wrote to read below...
Let's assume to put this simple `for` instead of the commented line (once at a time)
    for (var k:Number=0;k<listaIPCheck.length;k++)
      listaIPCheck.getItemAt(k).check = "checkVal";
      listaIPCheck.getItemAt(k).save = "saveVal";
This code always work in the 3 points, so at the end of the call the ArrayCollection is always filled with the new values, but the datagrid refresh the items only in POINT #1 and POINT #2
Why not in Point #3???

Thank you Amy, but adding the properties in the server side did not work...
The workflow of the program is that:
1) I get the ArrayCollection (listaIPCheck) contatining some information (function ro_resultHandler)
2) I start an external process and grab the output data (function init3)
3) read and use the data from the process (function onExit)
Now the problem I have is regarding the refresh of the datagrid, this datagrid has the ArrayCollection (listaIPCheck) as DataProvider.
So:
- If I put the for loop instead of the comments ( // Read Below {POINT #1} ) or
( // Read Below {POINT #2} ) it works, the ArrayCollection is updated and the datagrid is refreshed
- Whereas if I put the for loop instead of ( // Read Below {POINT #3} ) , it won't work.. or at least, the ArrayCollection is correctly updated, but the datagrid is not refreshed at all and I have to use .refresh()

DataGrid Horizontal Scroll Problem when datagrid contains Item renderer

I have datagrid with horizontal scroll policy enabled. Grid
contains some item renderer also.One of the item renderer is
datefield when i select a date from the datefield and say the
adjacent cell of the grid also contain datefield itemrenderer
and i am selecting date from that itemrenderer also.When i
scroll horizontally the date in the itemrender changes to any one
of the two itemrenderer.Some time it works fine.I am getting the
issue for combobox itemrender also.Can any one help me to solve
this issue.

DataGrid with styleFunction example posted

I've just uploaded a new example to my site, which is an
extended DataGrid
with a styleFunction added similar to the one that
AdvancedDataGrid has.
This also includes a StyleableRenderer class, which is a
simple itemRenderer
that extends UIComponent, if you've been wondering where to
start in order
to start writing your own UIComponent based itemRenderers.
http://flexdiary.blogspot.com/2008/09/extended-datagrid-with-stylefunction.html
Enjoy!

Hello
First, thank you for the help. I later had the same idea with the base class. Know there is some problem with the database. But that's an other problem.
So thanks for your help!
Actually I'm not sure which DataGrid I'm using. I'm quite sure it's not MX, Because I can't find any MX-Code. The DataGrid gets created with a function in its own class. (EntityDataGrid.as)
I do not get any error. The other objects just don't get viewed. (There is an exception rule)

Load DataGrid with a service information

Hello everybody, I'm loading one datagrid using one service (on Java) that give me some date to load a DataGrid but I have a problem. I want to call to more than one method and with this dates create an array, and then give the array to the dataGrid. The problem is that I get only one date with one call, and I want to get al the dates of the array with one call. Now I'm doing that, I load my datagrid with something like this:
Subject - Null - Null - Null
Subject - From - Null - Null
Subject - From - Date - Null
Subject - From - Date - Size
Subject2 - From - Date - Size
Subject2 - From2 - Date - Size
Subject2 - From2 - Date2 - Size
Subject2 - From2 - Date2 - Size2
Subject5 - From5 - Date5 - Size4
Subject5 - From5 - Date5 - Size5
And I want that:
Subject - From . Date - Size
Subject2 - From2 - Date2 - Size2
Subject5 - From5 - Date5 - Size5
Here the code
//The columns of the DataGrid
public var columnas:ArrayCollection = new ArrayCollection([
                            {headerText: 'R', dataField: 'leido', textAlign: 'left', renderType:'text',width: '5' },
                            {headerText: 'Asunto', dataField: 'subject', textAlign: 'left', renderType:'text', width: '100' },
                            {headerText: 'Remitente', dataField: 'from', textAlign: 'left', renderType:'text', width: '70' },
                            {headerText: 'Fecha', dataField: 'date', textAlign: 'left', renderType:'text', width: '35' },
                            {headerText: 'Tamaño', dataField: 'size', textAlign: 'left', renderType:'text', width: '40' },
                            {headerText: 'Adj', dataField: 'adjunto', textAlign: 'right', renderType:'text', width: '10' },
//Valing to my java service methods
public function onInfoResult(event:ListEvent):void {
            _service.addEventListener(ResultEvent.RESULT, tablaLoadedResult);
            _service.addEventListener(FaultEvent.FAULT, tablaLoadedError);
            for(var i:Number=1;i<5;i++)//To get 5 lines in the DataGrid
                _service.getSubject(i,'INBOX');
                _service.getFrom(i,'INBOX');
                _service.getDate(i,'INBOX');
                _service.getSize(i,'INBOX');
public function tablaLoadedResult(event:ResultEvent):void {
              var subject:String = String(_service.getSubject.lastResult.toString());
              var from:String= String(_service.getFrom.lastResult);
              var date:String= String(_service.getDate.lastResult);
              var size:Number = _service.getSize.lastResult;
               array.addItem({read:"T",subject:subject,from:from,date:date,size:size,adj:"A"});
public function tablaLoadedError(event:FaultEvent):void{
            textArea.text = "Fallo : " + event.message;
I don't know if I'm doing correctly or it's completly wrong.
Thanks!

Any suggestion? I'm a little lost and I need to do more things with this datas.
Thanks

Bug: Scaling DisplayObject with TextField Child

Hi,
my app has a number of DisplayObjectsContainers of type Sprite. Among others, these objects each have a TextField as their child. Scaling the Sprite object does not properly scale its child TextField. Also, in case the Sprite object is not scaled directly, but indirectly by adding it to a scaled Container, AIR 2.6 shows the same behaviour on the iPad. renderMode is set to gpu.
Seems to me like a bug, since the same code runs properly on desktop and on android.
How can this be solved??
Thanks in advance
LLD

So I'm the only one with this problem? I still hope to get some feedback on that one.
Below is a small class that shows the problem. Just add it to your project, instantiate it and put it on the stage. Don't forget to set renderMode to gpu and let it run on iPad and on other platforms. You see the difference?
Here's the code:
package
    import flash.display.Sprite;
    import flash.events.TimerEvent;
    import flash.text.TextField;
    import flash.text.TextFormat;
    import flash.utils.Timer;
    public class TestScale extends Sprite
        private var ScaleObj:Sprite;
        private var TF:TextField;
        private var _timer:Timer;
        private var _scale:Number = 1.0;
        private var _dir:int = 1;
        public function TestScale()
            super();
            this.graphics.beginFill(0x333333);
            this.graphics.drawRect(0,0,500,500);
            this.graphics.endFill();
            ScaleObj = new Sprite();
            ScaleObj.graphics.lineStyle(1,0x000000);
            ScaleObj.graphics.beginFill(0xeeeeee);
            ScaleObj.graphics.drawRoundRect(0,0,150,40, 6,6);
            ScaleObj.graphics.endFill();
            ScaleObj.x = 100;
            ScaleObj.y = 100;
            TF = new TextField();
            TF.width = 140;
            TF.x = 4;
            TF.y = 5;
            TF.defaultTextFormat = new TextFormat("_sans", 15, 0x000000);
            TF.text = "Just a scaling test";
            TF.selectable = false;
            ScaleObj.addChild(TF);
            addChild(ScaleObj);
            _timer = new Timer(200);
            _timer.addEventListener(TimerEvent.TIMER, onTick);
            _timer.start();
        private function onTick(event:TimerEvent):void
            _scale += 0.1 * _dir;
            if(_scale > 2.0 || _scale < 0.2)
                _dir = _dir * -1;
            ScaleObj.scaleX = _scale;
            ScaleObj.scaleY = _scale;
Thanks in advance for any helpful input!!

DataGrid Header shadow Problem.

Hello,
Here is my problem: I have this DataGrid with all kind of
custom styles, backgroud colors, cell colors, fonts. etc. I can't
figure out how to get rid of the black line right under the header.
It's like a 1px stroke solid black........Am I on Crack, is this
even possible? I know you can hide the header, but I want to keep
it for sorting purposes. Thanks for any help.

I think the column still exists even if you set its visibility to false. You could try something like this

Datagrid vertical scrollbar problem

I wrote a search function for a datagrid component. The
dataprovider is a ArrayCollection variable. If the item is found in
the array, set the item to be selected in the datagrid. The problem
is when the selected item is at bottom of the datagrid, the
scrollbar doesn't refresh so I have to manually move the scrollbar
to see the selected item. Here is part of my code:
<mx:Script>
<![CDATA[
......(populate accountData using dataservice)
accountDS.fill(accountData);
private function findAccountById(id:String):void
var size:int = accountData.length - 1;
for(var i:int = 0; i< size; i++) {
var account:Object = accountData.getItemAt(i);
if(account.accountNumber.search(id) != -1)
dgAccount.selectedIndex = i;
break;
]]>
</mx:Script>
<mx:ArrayCollection id="accountData"/>
<mx:DataService id="accountDS"
destination="accountlist"/>
<mx:Panel >
<mx:DataGrid id="dgAccounts" dataProvider="{accountData}"
editable="false">
<mx:columns>
<mx:DataGridColumn dataField="accountNumber"/>
<mx:DataGridColumn dataField="accountType" />
</mx:columns>
</mx:DataGrid>
</mx:Panel>

You need to look at the API for DataGrid. Particularly the
property "verticalScrollPosition".
The logic in your expectation that setting selectedIndex
should update the scroll position is flawed. What if you selected
an item with the mouse and then wanted to browse the other options?
You would use the scroll bar for this. Your selection might
disappear from the list but you would want it to stay selected.
Thus the scroll position and the selected index are completely
independent of one another.
The point I am trying to make is this: you are required to
set the verticalScrollPosition when you set selectedIndex if you
want them to work in concert.

Dynamically created textfields problem

Hi people,
I have a strange problem here: I want to create textfields
dynamically that are just big enough to hold the text to display.
The textfields use a font from the library. I get the metrics of
the text with TextFormat.getTextExtent(), it seems to work ok.
However, the last letters of the text are missing in the textfield
after assigning the text, when the text needs more than 1 line. The
textfield is sized for 2 lines, but the 2nd line is just empty. I
applied wordWrap, but the text doesn't show at the 2nd line. This
seems to be connected to the font that is used: I tested about a
dozen different types, and only 1 of them displays always the full
text, with all other fonts, the last 6 or so letters are missing.
The text property of the textfields holds the complete text; where
are the last letters?
So, are there any known issues with textfields created
dynamically? Or any trick to display all of the text? I'd like to
use a monospaced font, but all I have tested have this strange
problem.
Attached is the code used for creatiing the textfields.

Yep, the reason is I never tried that. :)
No... I'm just about to give it a try, but I want to draw a
fancy border around the textfield (other than the border that comes
with the textfield), so I guess I'll need the metrics info anyway.
Another thing is that I want the width to be not more than 150,
gotta check if that's possible with auto-size. Have to try that
now... thx for the input!

Datagrid with graphics ?

hello, I want to make a datagrid (without column headers),
that holds clickable bitmap images.
Can anyone direct me to a tutorial that will help understand
this process ?
thanks kindly

I have re read the Cell Render documentation and looked at
all the examples I can find of which there are only 3
all of them receive the data to populate the combo box from
hard coded arrays with in the actionscript itself, I could not find
a single example that receives the data for the datagrid and the
combo box from a remote source like a php script or text file.
I have been trying for days to get this datagrid combo box to
work properly.
I can get it to work if I put the data array in the
CellRenderComboBox.as file as follows.
this is what the examples show.
private static var COMBOBOX_DATA_PROVIDER : Array = [{label:
"unrated", data: 0},
{label: "low", data: 1},
{label: "medium", data: 2},
{label: "high", data: 3}];
when I declare it like that it works,
When I get the data from a data provider as follows it
doesn't work.
private static var COMBOBOX_DATA_PROVIDER = _root.cbdata;
However I can get it to work by putting a combo box on the
main stage with the same name as cbdata then it works.
Whats with this?
Why do I have to have a combo box on the stage for the ones
in the datagrid to work when pulling data from an external source?
I can't believe the difficulty i'm having doing this.
everything else has been quite easy.
And there seems to be very few comments or examples anywhere
of datagrid with combo box being populated from an external source.
There are examples of them being populated from within the
actionscript itself but not from an external source. I'm wondering
if there is some problem with this.
Can anyone see where I'm going wrong?
Or is it something that can't be done in flash?

HT1386 I just reinstalled my windows operating system and decided to put on windows 8. After loading all of my music back into a freshly installed itunes, my 4th gen ipod is not recognized by itunes. My 1st gen ipod nano works with no problem. Help!

reinstalled my windows operating system and decided to put on windows 8. After loading all of my music back into a freshly installed itunes, my 4th gen ipod is not recognized by itunes. My 1st gen ipod nano works with no problem. I can eliminate any problems with the cable and connection.
I've stopped and started the service, and also have performed cold reboots.
Nothing seems to have helped the situation.
Help!

See:
iOS: Device not recognized in iTunes for Windows
I would start with

Have you tried on another computer to help determine if you have a computer or iPod problem?
The iPod Classic uses different drivers than the Nano
