• Removing collection ArrayCollection object element

  If I have an ArrayCollection collection like this:
  
  public var myAC:ArrayCollection = new collection ArrayCollection ([{name: "first of all, the price: '10' '}]);
  myAC.addItem ({name: 'second', price: '20'});
  
  For example to remove {name: price "First': '10'"} point myAC?
  
  Thanks in advance

  myAC.removeItemAt strives to remove items.

  Or...

  myAC.getItemAt (0) = null;

  var temp: collection ArrayCollection = new ArrayCollection();

  for (var a: uint = 0; a)< myac.length;="">
  {
  If (myAC.getItemAt (a)! = null)
  {
  temp.addItem (myAC.getItemAt (a));
  }
  }

  myAC.removeAll ();

  myAC = new ArrayCollection (temp);

  Who can solve the problem. The idea makes sense, but I did not test the code.

• How to browse the collection ArrayCollection?

  I have two datagrids and you want to move items on datagrip and fill the other.  Here is a screenshot of a Visual screen.

  

  In the screenshot on I can add some names/sex to the datagrid on the left using the text input and the Add button.  I can select the checkboxes for each name of ros as well. I want to do is move the check names in the datagrid control on the left for the datagrid on the right.  4 max.  But if I chose only 2 name, both names would be added to the 1 Racer and Racer 2. Runner 3 and 4 of the race would be left blank.  If I check the new names and submitted it would be in a new line on the left data grid.

  What I can understand is to scroll the datagrid control left and find only the lines of control.  To the right of the datagrid can be quite easily as soon as I figure out how to identify what is checked and what is not checked.

  This is the datagrid on the right.

  "" " < mx:DataGrid x ="10"y ="76"height ="337"id ="list"editable ="false"dataProvider =" rosterArray{}">

  < mx:columns >

  < mx:DataGridColumn headerText = "" width ="30">

  < mx:Component >

  < mx:CheckBox / >

  "" < mx:DataGridColumn headerText = "sex" dataField ="sex" width = "40" "editable ="false" / >

  "" < mx:DataGridColumn headerText = "time" dataField ="time" width = "45" editable ="false" / >

  < / mx:columns >

  < / mx:DataGrid >

  The function add to my rosterArray (left datagrid) is below.

  private function rosterAdd():void

  {

  rosterArray.addItem({name:addName.text,sex:sexGroup.selectedValue.toString()});)

  addName.text = ""; empty text entry field.

  }

  I guess I have to scroll datagrid and not the rosterArray because I don't have a place for the checkmarks in the rosterArray.

  Any help idetifying which lines are checked in the left data grid would be much appreciated.

  Thank you.

• collection ArrayCollection collection arraycollection assigned values from the original setting?

  Hi... I am pretty stumped on this one. Here's the situation... on my main flex app I define an arraycollection collection:

  public var fiscalYrsArray:ArrayCollection;

  The collection is filled with the results of a query to a CFC

  protected function fiscalYrs_resultHandler(event:ResultEvent):void {}

  for (var x: int = 0; x < event.result.length; x ++) {}

  If (event.result [x]. DATA == passData.filterFiscalYrs) {}

  Event.Result [x]. Assigned = true;

  }

  }

  fiscalYrsArray = event.result as ArrayCollection collection;

  }

  I have a main application with drop-down menus window (I use a multi-case combobox). I use this window as a filter window, where users can choose what they want filtered.

  on this component, I use a temporary arraycollection collection (b/c I don't want to change the assignments of the arraycollection the temp collection is based off of) which will be a copy of the fiscalYrsArray of the parentApplication collection:

  " < = xmlns:fx s:TitleWindow ' http://ns.Adobe.com/MXML/2009 'close = "PopUpManager.removePopUp (this)'

  xmlns:s = "library://ns.adobe.com/flex/spark" title = "filter data" creationComplete = "initComp (); »

  {for each (var point: Object in {this [comboId] .selectedItems)}

  This element of += [filterVal] ['DATA'] + ",";

  }

  filterChange = true;

  idText.text = str;

  }

  I am lie the collection arraycollection filterYrDP to a custom choice multi combobox:

  < multiPickBox:CheckCombo id = "fiscalYearF" width = "162" dataProvider = "{fiscalYrDP}".

  addItem = "msc_addItemHandler (event, 'tempfilterFiscalYrs', 'fiscalYearF')" "

  allIndex = '0' x = "77" y = "17" labelField = "DATA" / >

  However, I find that when an element is activated the assigned = true value is actually applied to the fiscalYrsArray of my parentApplication origin. I just want the assigned = true to apply to the fiscalYrDP collection arraycollection (one that is based on the fiscalYrsArray of parentApplication). How could it be written back and changing the properties of a fi main is just a temporary copy?

  By assigning the table using "=" you are just assigning the same table - in the same memory location.

  If you want to keep a separate table, you use the function ObjectUtil.copy

  import mx.utils.ObjectUtil;
  
  arrNewData  = new ArrayCollection();
  arrOldData  = ObjectUtil.copy(arrNewData) as ArrayCollection;
  

• GetItemAt collection ArrayCollection

• Problem with allocating memory collection arraycollection by AddItem

  I have a strange problem with the AddItem method.

  I made a new item with this code:

  ------

  for (var u: int = 0; u < 41; u ++) {}
  Page = new PageToSave();
  project.addPage (page as PageToSave);
  }

  -----

  the project is a distance of class projectblueprint:

  package marcoDoItBetter.utils

  {
  private var _pages:ArrayCollection;

  public void addPage(page:PageToSave):void
  {
  This._pages. AddItem (page);
  }

  }

  }

  PageToSave is a class that extends the object.

  I don't want duplicated instances, but I want independent authorities.

  project.addPage (page as PageToSave);

  is a garbage collector from?

  How can we solve this problem?

  Thank you

  Hello

  From the looks of it, looks like a bug.

  Are you defining filters or performs a sort on the ArrayCollection collection? Or it's just a pure naked collection instance ArrayCollection.

  Have you tried addItemAt() and got the same result?

• Display collection ArrayCollection in a list and the ArrayCollection with Drag and Drop collection reorgnize

  I have an ArrayCollection collection created like this

  qaAC = new ArrayCollection();

  for (var i: int = 0; i < 10; ++ i) {}
  var o: Object = {question: ' what is "+ i +"? ", answer:" it's "+ i"};
  qaAC.addItem (o);
  }

  The ArrayCollection collection is an array of object that has properties "question" and "answer to" custimized.

  I want to put 'issues' in the ArrayCollection collection in a list. 'qaAC.question' does not return an array of questions for me.

  I have to extract the ArrayCollection collection to form a new String table, and use the new array as the dataProvider of the list of questions.

  Is there a way better and clean?

  My goal is to use a list to reorgnize an ArrayCollection collection that contains complex objects (not simple string) with Drag & Drop. Is this possible?

  Any suggestions?

  I put two lists in my example to show how the ArrayCollection collection could be displayed in two different ways. You don't have to have two lists if you do not need them.

  When you change the order of the list made with drag and drop, you change the order of the collection ArrayCollection qaAC, so all the controls that display the qaAC will also be updated to reflect the new order. You can test this in the example I posted earlier. Change the order in the list of question and you will see the order change also in the list of responses. This is because they are both bound to the same collection of ArrayCollection. If you want to behave independently, you need two separate ArrayCollections.

• Enter the filtered items in collection ArrayCollection after such FilterFunction

  It is an easy one. I have my filtering function, but rather than use main ArrayCollection collection after it has been filtered, I want to retrieve all filtered items and pass them in another collection ArrayCollection.

  private var allScreens:ArrayCollection;

  [Bindable]
  private var filteredScreens:ArrayCollection;

  private void filterFunc(value:Object):Object
  {
  If (Number (value.module_number) == 1)

  {
  Returns true;
  }
  Returns false;
  }

  
  private void filterSuff(value:Object=null):void
  {
  allScreens.filterFunction = filterFunc;
  allScreens.refresh ();
  
  for (var i: int = 0; i < allScreens.length; i ++)
  {
  If (allScreens.getItemAt (i) .module_number == 1) {}
  filteredScreens.addItem (allScreens.getItemAt (i) .filename);
  }
  }
  
  trace (ObjectUtil.toString (filteredScreens));
  }

  Hmm, addAll() is a function for the ArrayCollection with Flex SDK 3.3 collection, but I guess not in some versions.  A loop could perform the same function.

  var point: Object;

  for each (item in the original)

  {

  filtered.addItem (item);

  }

  Let me know if it does the trick.

• Help!  How to upgrade two dimension collection ArrayCollection?

  Hello
  
  I'm having a problem of understanding of documentation on populating a DataGrid of two dimension collection ArrayCollection. My situation is that I have a DataGrid with a bunch of information, currently stored in a two-dimensional array (digital in the first dimension and by field name in the second dimension). I also have a bunch of data streaming from an XMLSocket, which, when it happens, is analyzed, resulting in one of the fields of the table in need of update. I can do very well with the table directly, but I can't try to understand how use the ArrayCollection collection features to cross this two-dimensional structure - setItemAt() does not seem suited for this purpose? I need to trigger the effects on the relevant cell that has been updated, when I round coding, so I will try to use some structure that handles update events and others for me automatically, such as the ArrayCollection collection.
  
  I do not know is still the best technique to use, and the intermediate level (the ArrayCollection collection and others) could be changed completely, so if you can suggest (and illustrate, if she is as confused as this!) a better method, I would be grateful.
  
  Thank you
  
  David
  

  Ah.

  You must look for the item in the collection ArrayCollection. This is usually done with a loop in the collection. When you have found the item you would:

  Item.Quantity = new quantity;
  dp.itemUpdated (item);

  You must call the method of collection itemUpdated to make the signal Collection all interested parties (for example, the DataGrid bound to her) she's changed.

  A Collection can also views and ViewCursors that might be useful to have a lot of data.

• Filter collection arrayCollection based on elements in another table?

  I have a table that contains several values: ["361 364"] = array1
  
  Here's the id references that change frequently.
  
  I have an arrayCollection collection that contains a bunch of files. I have experience of writing code to perform simple filtering of my collection arrayCollection using the filterFunction function and a simple piece of criteria.
  
  I am trying to reach a loop for filtering my arrayCollection collection to look at the number of element in array array1 and then filter my arrayCollection collection, leaving only entries that match the id numbers in array1.
  
  I am using a ".. for each" loop but I do not understand the result I need...
  
  Sample:
  
  public var matchingID:int:
  
  private function filterArray (): void
  {
  for each (var i: int array1)
  {
  matchingID = i;
  arrayCollection.filterFunction = checkIDs;
  }
  arrayCollection.refresh ();
  }
  
  private void checkIDs(item:Object):Boolean
  {
  If (item.id is matchingID)
  {
  Returns true;
  }
  on the other
  {
  Returns false;
  }
  }
  
  
  When I run this code I find myself alone with a collection consisting of single entry, arrayCollection which is the last. My brain is frozen trying to understand this one. The values and the amount of values will vary in array1 I am looking for a loop of filtering for arrayCollection collection that works no matter how many values of array1 is.
  
  Any creative ideas?

  You wanted to probably say array1 = [361, 364], right?

  Course 2
  
  
  Course 3

  ;

  you need to do collection here ArrayCollection instance before put something u.
  this.myDataDistinct = new ArrayCollection();

  E4X selection
  var xmlList:XMLList = myData.course.name;

  for each (var xml in xmlList)
  {
  trace (XML); you will see that we have now.
  var str:String = new String (xml);
  var flag: Boolean = true;
  for (var i: Number = 0; i
  {
  If (this.myDataDistinct.getItemAt (i) == STR)
  {
  flag = false;
  break;
  }
  }
  if(flag==true) {This.myDataDistinct.AddItem (STR) ;}
  }
  }

• Collection ArrayCollection clone

  [Salvation all THE]
  
  I decided to create a new topic for a problem in another... never mind: P
  
  Simple question
  
  I had a myOriginal (collection ArrayCollection), clone/where you want it and call the new: myCloned (collection ArrayCollection).
  
  myOriginal cannot be updated any more.
  
  This is my code so far but it stills updated the original Collection. I prove that by the loop and the trace of the original Collection.
  
  
  [Bindable] private var myData:ArrayCollection;
  [Bindable] private var myCloned:ArrayCollection;
  
  private void resultHandler(event:ResultEvent):void {}
  myData = event.result.db.data; Original data
  cloneOriginal(); Perform cloning
  myData.disableAutoUpdate (); It is wrong... in the 'core' still updates... I think so..
  }
  
  
  private function cloneOriginal (): void {}
  var myCloned:ArrayCollection = new ArrayCollection();
  for (var c:int = 0; c < myData.length; c ++) {}
  myCloned.addItem (myData [c]);
  }
  
  
  Thanks in advance... ;)
  Base on...

  Thank you for using Clara, after some time, I've done the correction :)

  Final code, thanks to anyone are [[]]:

  "- How do I clone an ArrayCollection collection.

  Import mx.utils.UIDUtil;
  Import mx.collections.ArrayCollection;
  Import mx.rpc.events.ResultEvent;

  [Bindable] public var myOriginal:ArrayCollection;
  [Bindable] public var myCloned:ArrayCollection = new ArrayCollection();

  FLEX THINGS...
  public void objectCopier(toAdd:Object):Object {}
  var addME:Object = clone (n);
  addME.mx_internal_uid = UIDUtil.createUID ();
  return Alain;
  }

  public void clone(source:Object): * {}
  var myBA:ByteArray = new ByteArray();
  myBA.writeObject (source);
  myBA.position = 0;
  Return myBA.readObject ();
  }
  END

  public void resultHandler(event:ResultEvent):void {/ / result of a HTTPService...} For example, of course...
  myOriginal = event.result.db.data;
  myCloned = clone (myOriginal); THE ACTION IS HERE

  hList.dataProvider = myOriginal; Stay forever with these data
  hList2.dataProvider = myCloned; Table working on it
  }
