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.

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 :: 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 :: 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:, ...},

Flex :: Data Passed From DataGridColumn.itemToLabel To DataGrid.itemRenderer.set(data)?

Dec 4, 2009

I have a DataGrid whose dataProvider is an Array of int Arrays (each with different lengths). Since each row has variable size (and I want to display all the data), I decided to extend DataGridColumn and overwrite the itemToLabel function to be able to display the data. The problem is that I also need to display the data differently depending on the int value.

I believe the only solution is to write an itemRenderer, but the only input the itemRenderer.set(data) function receives is the entire int Array. I believe I need either the exact string returned by itemToLabel or the column index of the cell the itemRenderer is for (to basically do the same parsing I implemented in itemToLabel).

Flex :: DataGridColumn Display Multiline String Data?

Aug 18, 2009

Is it possible to display a multiline string in a Flex DataGridColumn?i.e. Display:

Text line one.
Text line two.

I've tried putting "

","
","&#13;" when storing the string but nothing seems to work.Currently only "Text line one." is displayed and the rest is hidden in the cell. I would prefer not to use "wordWrap=true" to emulate this behaviour in the cell, but instead be able to manually put in newline breaks (although I could turn on wordWrap to avoid long text from hiding due to cell dimensions).

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?

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.

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>

ActionScript 3.0 :: Adding Data Into Array Of Generic Objects?

I am able to add key/pair data into the associative arrays, like;

arrColors.push({color: "beige", code: "0xF5F5DC"});
arrColors.push({color: "brown", code: "0xA52A2A"});
// and so on

But, if I want to do the same with the array of generic objects, like;

Code:
var obj: Object = new Object();
obj["key"] = "value";

How can I add more data into it, because push() function does not seem working with this type of array.
