I have a data grid who's data provider is set to an XML object.

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.
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:, ...}

View 1 RepliesI 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?
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.

I have a dataProvider and there is an object in the dataProvider. I want to know if there is a way to see if you can check to see if part of the object exists. So lets say I have an object with usernames and passwords and I want to add a username to that dataProvider
View 1 RepliesI 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?
View 2 Repliesi 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();

This is my XML data in a file named nodesAndStuff.xml.

Now I have added my tree just below the list and I have saved counting from 10 to 19 in one.xml, 20 to 29 in two.xml and so on in different XML file. I have no clue how to connect the XML containing counting from 10 to 19 as the single node in tree at the selection of label one in list

I'm currently working with the OLAPDataGrid component and got stuck at a relatively simple task: I want to style the last row of the grid differently from the rest, so my cell item renderer needs to know whether he's rendering the last row with content in the overall grid, including those rows currently not rendered because they are outside the visible grid space. AdvancedGridListData's rowIndex property only gets me the row index of the renderer relative to the range of visible grid rows, i.e. when I scroll down the grid, a data item with an index greater than 0 gets the rpw index = 0.
View 2 RepliesI 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?
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.
View 2 RepliesIf user change the value of the TextInput, then click refresh button to retrieve the data model from backend again, the GUI value will not change back. Re-binding not happen, Since the value of data model not changed, no propertyChanged event fired.In this case, I must Programmatically set the model value to the GUI after data refreshing done.I know bi-directional binding can solve this problem(when user change value on GUI, set the new value to data model immediately). But sometimes I cannot use bi-directional binding, for example, the data model is a int, but user input a non-int value, I cannot set the value to data model. So the value in data model do not change, when refresh data, rebinding still not happen.
This will make the data binding useless. How to resolve this?I put pseudo-code here for now, I will put real code later:1. retrieve a data model from server, via blazeds or something else.2. bind the model to a TextInput on GUI.3. user change the TextInput text.4. User click a refresh button, triger retrieve the model value again.5. Now since the model value do not change, no PropertyChanged event fired.6. GUI value still is the user's input, not the value from the model. can clear the model value before set the velue back, make re-binding happen.(but sometimes you do not know how to clean the model value, take int for example, you may do not know the original value and happen set the same value). Or I can manually set the model value to GUI. But both are not good looking.

I have a Data Grid with automacticly genorated columns, i now need to add data items into a spesific row / column of this grid e.g. col 2 row 3. It dosnt have a data provider at the moment as i wish to be very selective about which data goes where.

View 2 RepliesI am working in Flex3. Here I have a datagrid which contains data. some columns are editable. when the user changes the column data web service is called. Here using function of focusOut, I am calling the web service by sending the data which comes from the datagrid through focusOut function. Now I want to call the web service when the user changes the column data and presses keyboard key 'Enter'. Here I can call function but the event does not carry datagrid's data to the function being called.
View 3 RepliesI 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>
