Flex :: Data Cannot Be Grouped Outside App And Return ArrayCollection
Sep 23, 2011
I have flat data in my app which I will need to group, summarize, and count as I normally would with a sql query. For this project though, it must be done in the flex app. I need to figure out how to group my data by day or month using a datatime field in my Arraycollection, then appropriately count or summarize data in other fields. I've used Groupingcollections before, but only when binding to hierarchical controls (like AdvancedDataGrid and Tree), but I need a resulting ArrayCollection with the grouped and summarized data. Basically, I'm trying to access my AC like a sql table (GROUP BY MONTH(datetime), COUNT, COUNT(DISTINCT(), etc.) and I'm unsure how to do it.
I am trying to display grouped data in AdvancedDatagrid but the data does not show up. When I specify the dataprovider without the grouping collection I am able to see the data. Is there something wrong with this code?
My code is: var dataList:ArrayCollection = new ArrayCollection([{name:"alauddn"}, {name:"ansari"}]); private function getItemInd(event:MouseEvent):void{ var item:Object = new Object(); item.name = "ansari"; var ias:int = dataList.getItemIndex(item); Alert.show(ias.toString() + ": " + item.name); } But it returns "-1:
I've got a Gridcolumn in a Datagrid (Spark). The Column's dataprovider is a Number value that gets updated via Binding.Now, without an item renderer the cell displays the correct values.If I set an item renderer, I can't access the values in this renderer.My renderer looks like this, so nothing really do here (for now) but to trace the value, but the value is always NaN.
I have an xml file (externally saved) that is similar to the following:
[root] [main] [title]...[/title]
[Code]....
What I like to do is to get what's in [title] tag using HTTPservice, import it into Flex, and save it as array objects, and do the same thing for [content]. This way I can later refer the array object saying title[0] or content[2].
I have xml file with data as below and i want to convert this into Flex ArrayCollection including the id and name of the tags. I am using httpService to get the file.
I'm working on a flash cards application and am using an ArrayCollection of Objects to store each cards individual data. When the user click the 'save' button, the text from the two textAreas and the 'title' textinput are stored in the AC as one object with .title, .side1 and .side2 properties that contain the text from the flash card. I have made a List in a separate class I want to have display the title of each card the user has created, but after days of researching and looking around, I still cannot get the display to list the titles.
Part of my NewCard.mxml: <?xml version="1.0" encoding="utf-8"?> <fx:Script><![CDATA[ import flash.events.EventDispatcher; import mx.collections.ArrayCollection; import spark.effects.SlideViewTransition; [Code] .....
Here am getting array of groups(groupName,GroupID each row ) from a RemoteObject and displaying in a ComboBox. I am selecting the groups with selectedIndex as 0,1,2,3, but I want my groupIDs of correspoding groupnames,which am bringing to client side.
How can I get actual the groupId of the selected group?
My label text is not showing up after binding the arraycollection to the label text. Could I see an example of how to properly bind an arraycollection to a labels text?
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;
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 an ArrayCollection of Objects. Each Object with three attributes:CustomerID, Income and DateMy goal is to chart this data for each customer (or a couple together) in a Income by Date LineChart display. Selection of customers is done with ArrayCollection filters.Data is fetched from an SQL database, however, each customer has some data points missing.f there was zero income on August 8, 2010 there will be no entry for that.Charting the ArrayCollection as is, is misleading because there is no indication of the missing data points.One way to solve this is to artificially add zero points for the missing dates for each customer. However, this would explode the data set (and impact performance).
The problem lies in the fact, that when the ArrayCollection _data is filtered (because the Checkbox "Even" is set), then the 2nd loop in the test case (for adding new items) adds items (the "35") again and again - because it's filtered and thus not visible.
I have a Flex tree with an ArrayCollection as data provider. The ArrayCollection is composed by objects linked eachother by the "children" field (that is an Array containing other children objects)
In my AIR app i am trying to get the names from sqlite database as an ArrayCollection . Here is my code.
private function visitorName():void { var sqlText:String = "SELECT name FROM user"; visitorNames = new SQLStatement;
[Code].....
What should i do to get the results to an ArrayCollection by calling the visitorName() function? Is it possible to get return value from a nested function?I know the visitorName function should be changed to ArrayCollection type and should declare an ArrayCollection variable inside it .. but not so sure how to proceed .
I have a component where I expose the property 'questions' with the following code:
private var _questions:ArrayCollection; private var questionsChanged:Boolean; [Bindable("questionsChanged")]
[Code]....
In this component, I use commitProperties() to implement my logic.
I use Cairngorm and the 'questions' is in the model and hence it's defined as a source for data binding.
When the 'questions' ArrayCollection's size changes elsewhere in the application, it is not invoking the setter method in the component that is destination for the data binding.
I'm trying to export an AdvancedDataGrid to CSV. This is easy enough for non-hierarchical data, but when using a HierarchicalCollectionView to show treed data it gets trickier.
how to access each of the cells just as they appear on screen when all of the nodes are expanded?
I#m looking for a solution to sort all grouped colums in advancedDatagrid. It should be the same behavior like clicking in a columns head. i'm not looking for a solution to sort the fields IN a the grouping. There is working solution named compareFunction. But I'm not able to sort the two rows in my picture by column "Einnahmen". Sorry for the german word.
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:
Is there a way to have ungrouped and grouped items mixed in the same datagrid?
For example, think of a grid that lists the root items on a C: drive.
Obviously, we would want the Directory Structure to be group and expandable. But the files on the root drive would also be shown on the list, however they would not be grouped.
When I do user.login(), it sends a request with a HTTPservice from my external AS class. In the result event handler for this httpservice, I set a public variable to true or false, depending on whether the user's credentials are correctly in the DB.
I then use a getter to get that boolean value. However, without the timer, it always returns false because my code is faster than the event result handler. If that makes sense.
So I have to use a timer to stall my application for one second.. But seriously, that doesn't make sense to me. There has to be a better way, no?
linedataColl is an AC that contains 100+ of rows extract from CSV, I wish to add item into SuperDataCollection object by object but the only problem was I'm unable to see any data display in "S" which is a datagrid. What wrong with my code?
var superDataCollection:ArrayCollection = new ArrayCollection(); var dc:ArrayCollection = new ArrayCollection(); var di:Object = new Object();[code]......
I know this one might be easy but I couldn't figure out.I have a List control that retrieve multiply data from Mysql. When a use clicks the data on List, The datagrid will display the data and the product image will show.I can see the multiply data shown in my dataGrid, but I don't know how to get the individual data shown.
I have been trying to populate a tree control via an httpservice that uses php to talk to a database. The queries work fine and the data comes back in the following format from php: echo "<root>"; echo "<topic>"; echo "<sectioncode>$sectioncode</sectioncode>"; echo "<children>"; echo "<labtitle>$title</labtitle>"; echo "</children>"; echo "</lab>"; echo "</root>";
Flex can see this and interprets the heirarchy fine unless i try to format the resultformat in the httpservce (if i do that it goes a little nuts). The results from the php query to the db come back as an ArrayCollection with each containing a "root->topic->sectioncode->title" type of structure (which is what I want). When I go and try to use this Arraycollection as a dataprovider for a tree control, it doesn't work at all. When I use the arraycollection as the dataprovider I get [object,object] for every row in the tree and there is no parent/child structure.
Ideally I would like the title to be a child of the numbercode, but when i try and format the return from xml like that the number becomes and object without a value and the title becomes a child. I have a feeling that I am missing something in the php return to show the structure to flex more clearly and also something in the tree to implement it as the data provider better. Here is the code that I am using in the tree: <mx:Tree x="25" y="48" height="451" id="ilabtree" dataProvider="{labarray}" labelField="@title" width="152" textAlign="center"></mx:Tree>
I have a somewhat complex parent/child hierarchy object that I need to display in a tree format that dynamically updates. To pass it into the tree as a dataprovider I convert the top level parent into an Array and then into an ArrayCollection. The problem there is if anything changes in the hierarchy the tree isn't dynamically updated unless I regenerate the dataprovider.
EDIT: I didn't have much code shown so I just tried to include the skeleton version of how everything is being used below, the tree works fine and even when I remove/add nodes the changes are evident but the vertical scroll bar isn't updated(doesn't resize) and if I scroll the tree will get out of whack and may display whitespace at the bottom of the tree where the item was just removed.
I tried just a plain bindable ArrayCollection test object with multiple levels and it updates properly so I think my tree is fine it's just how I'm trying to bind the dataprovider that I'm having the issues.
AS3 Class 1 - Object that can have plenty of child objects of itself by calling insertCustomObject()
public function CustomObject() { } public function insertCustomObject(customObject : CustomObject) : void {
I know how to display data in a List control using dataProvider but what about control that don't have dataProvider e.g. TextInput, Label contorl?[code]Try to use {dp.ID} and {dp.getItemAt(0).ID} on TextInput but nothing being display?How to make TextInput id=" first Name" able to display the SQL data?
