I have a data grid who's data provider is set to an XML object.
Code:
<mx:DataGrid id="streamMonitorGrid" dataProvider="{_data.stream}" height="100%" width="100%">
[code].....
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 have a radio button group within a data grid, whenever I attempt to change the selected radio button the web page crashes. Below is how I put together the radio button in the data grid.

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:, ...}
]
I have a datagrid and the dataprovider for this grid is the result of a RPC call. The result set has the following structure[code]...
View 2 RepliesHow 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.

when we use an advanced data grid, only when we click on the parent element the children details get populated in the corresponding columns, right?..SO now i have made the empty columns invisible(at design) now how do i make them visible at run time when the parent element is expanded..similarly once the columns are visible, how can i make them invisible again when the parent element is closed.

View 1 RepliesAs 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.

I've been working with the flash data grid component, and I want to update just one cell in the data grid without updating the entire dataset. I haven't found anyway to do this and the object inheritance makes it really difficult to track down properties of specific child elements. Here's a snippet i use to get data from a specific data cell:
var cellData:String = _currentPlaylistDataGrid.columns[0].itemToLabel(_currentPlaylistDataGrid.getItemAt(_c urrentSlideID));
What's the best way to do this? It's NOT on a click event or interactive event.

In Flex, using AdvancedDataGrid, I'm trying to achieve a drag and drop of one row's column data to another row's column or the same row but different column. Is this even possible? I've been googling for hours and all I can find are drag and drop whole columns just to rearrange their view order.

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.

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?

private function getList(e:Event):void{

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?
