ActionScript 3.0 :: Update Data Provider?

Nov 26, 2011

As i understand datagrid only is used as a form to present the loaded data in.So when we add new row to component or try to modify the value in cell and save it (xml file), we won't see those changes in saved file. So can some one explain to me or direct me to tutorial on how to update data in dataprovider, and how to save it to xml file.

Flex :: Update Hierarchical Data Provider In Advanced Data Grid During Drag And Drop?

Nov 11, 2010

I am trying to drag and drop hierarchical data in the same advanced data grid, and I would like the data provider to updated when the ADG is updated. (I want to be able to save and load this tree, so it is important that drags and drops are saved.)

[URL]

The sample app has an ADG showing hierarchical data as well as flat data. The first column of each datagrid shows the rowindex of the underlying data.

If you rearrange the items on the left ADG, the row indexes become unordered. If you click traceTree you see that the data provider is not in order.

On the other hand if you do the same on the right, the row numbers stay ordered even when the objects move around and if you click traceFlat, the data provider is in the order shown on ADG

My goal is to have the data provider order match the ADG order for the left grid which is displaying hierarchical data.

Flex :: Differentiate Between A Data Provider Update And A Itemrender Being Recycled When Using A Custom Itemrenderer In A DataGroup?

Oct 18, 2010

How do I differentiate between a data provider update and a itemrender being recycled when using a custom itemrenderer in a DataGroup?I have overridden the set data function of the custom item renderer, but I have found that on making a change to the ArrayCollection used as the DataProvider some of the item renderers are not assigned the same object they had before the update. This has made it almost impossible for me to distinguish between a data update and an itemrender being recycled. Also, the data never seems to get set to a value = null, so that seems to be out as well.

Flex :: Same Data Provider For Chart And Data Grid?

Aug 18, 2011

I want to display the same data in a chart and a data grid. I want to use the same data provider for both of them to reduce the amount of SQL queries.How do I transform the database structure into the chart structure and into the table structure using ActionScript?*

Database structure in JSON format:

[
{key:, year:, value:},
{key:, year:, value:}
]


Data provider structure required by a chart:

[
{series1:, series2:, year:},
{series1:, series2:, year:}
]

Data provider structure required by data grid:

[
{key:, year2000:, year2001:, ...},
{key:, year2000:, year2001:, ...}

ActionScript 3.0 :: ArrayCollection As Tree Data Provider

Mar 11, 2009

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>

Flex :: Filter The Data Provider For A Tree?

Mar 23, 2012

I have a requirement to filter the tree similar to that of flex builder-->preferences wizard tree.

My tree dataprovider is arraycollection of industries. Each industry has a list of sub industries and further, say upto depth 5.

So when we type in a string to filter, only the node having this string along with their parent hierarchy should be returned.

How can we implement this using flex?

Flex :: DataGridColumn With Array Of Objects As Data Provider

Mar 12, 2010

I have a datagrid that uses an array of objects as the data provider. The objects are essentially key/value pairs:

{ foo:"something"}
{ bar:"hello"}
{ caca:"lorem"}

The datagrid has 2 columns. The first column is the key and the second column is the value. Right now my grid looks like:

My dataFormatter function makes sure that depending on the column (i.e. the dataField value) the correct key or value gets printed out. This works fine for displaying. However, as soon as I try and edit the value field it essentially adds a new value into the object with a key of '1'. For example, if I edit the {caca:"lorem"} object it will then contain the value {caca:"lorem",1:"new value"}.

Is there any possible way I can set the DataGridColumn so that when I edit a value it will update the value associated with the key rather than inserting a new value? I've tried using a custom item editor but it still does the insert. It seems like I need to be able to update the 'dataField' with the actual key value but I'm not sure how to do that.

Forcing Menu To Refresh After Modifying Data Provider XML

Apr 15, 2009

When updating the data provider for a menu bar component, the state of the menu items fails to update until the user interacts with the menus (rolls the mouse over them, clicks them, etc). For example, a disabled item remains enabled until the user roll the mouse over it. Is there a way to force a menu 'refresh' after modifying the data provider XML?

Flex :: Get The Item Parent In A Tree When Using Nested Objects As Data Provider?

Jan 11, 2010

I have a Flex tree with an ArrayCollection as data provider. The collection holds an array of CategoryVO objects. Each object can have another array of CategoryVO objects inside it's "child" attribute. This way the tree displays the data correctly. Now I want to get the parent of a specific item, e.g. tree.selectedItem. Using XML as data provider the item parent is avaiable thorugh the parent() method. But I can't convert my data to XML. How can I get an item's parent? Perphaps using the tree's dataDescriptor?

Flex :: Flash Builder - Data Provider Not Working If XML Has Single Node Value Or Less

May 20, 2010

i get this error when i retrieve an XML that only has 1 node (no repeating nodes) and i try to store in an ArrayCollection. -When I have MORE than 1 "name" nodes...i do NOT get an error. My test show that XMLListCollection does NOT work either.

TypeError: Error #1034: Type Coercion failed: cannot convert "XXXXXX" to mx.collections.ArrayCollection.

this error occurs as the line of code:

myList= e.result.list.name;

Why can't ArrayCollection work with a single node? I'm using this ArrayCollection as a dataprovider for a Component -is there an alternative I can use that will take BOTH single and repeating nodes as well as work as a dataprovider?

code:

[Bindable]
private var myList:ArrayCollection= new ArrayCollection();
private function getList(e:Event):void{
var getStudyLoungesService:HTTPService = new HTTPService();

Flex :: Spark List : Show Subset Of Data Provider Based On Parameter

Aug 1, 2011

I have a situation where I have a List showing a queue of Upload Objects:

[Code]...

I would like to create three different views of the List: One showing All uploads in the queue Another showing only the Upload items with Upload.type == "Update" and another showing only the items with Upload.type == "Create". Another example of this would be on an email inbox, where we could filter "All, unread, or read". I realise I could just create three different lists, one for each view of the list (maybe I'm just being picky) but I was wondering: Is there is any easy way to conditionally select the items to display from a DataProvider based on a parameter (for example type =="Upload") so I don't have to juggle three separate ArrayCollections about?

ActionScript 1/2 :: How To Automatically Update Xml Data For Xml Connector

Apr 12, 2010

I have a project with an XML Connector that goes out and gets data from an xml file and displays it in a label in my flash. It does this when the swf file loads using ActionScript in frame 1. The ActionScript is simply: this.labels_xc.trigger(); It loads the data from the XML file no problem.  But the data in the XML file changes every so often.  How do I get the swf file to go out and get the new data on a regular interval (say every 2 minutes or so)?  I've looked at scripts with timers and I can't figure it out. Here is the url to the page I'm testing it on:[URL]

Flex :: Update An Image Dynamically Using Data Binding?

Feb 20, 2010

I have a main.mxml application that lays out my application, it contains a "browse and upload" button. And contains an image to view the users uploaded image like so:

<mx:Application
<mx:Script>
<![CDATA[

[Code].....

In my myModel class I have a img_scld_bm that the browseAndUpload() function draws into after scaling it.

My intent is that my mx:Image will display the image. As shown here I'm assigning the image source="mymodel.img_scld_bm", this ends up just showing a broken image icon.

I also tried data binding, where in my myModel class I have [Bindable] var img_scld_bm. And then tried setting my mx:Image source="{myModel.img_scld_bm}" .. that didn't seem to do anything either. All this compiles fine, no warnings. I think in this case, I'm not setting a trigger or propertyChange event to update the binding?

how to correctly bind an mx:Image source to some bitmap?
