Flex :: Sort AdvancedDataGrid With Hierarchical Data?
Mar 29, 2011
I have an AdvancedDataGrid with a HierarchicalCollectionView as its dataProvider. When I view the grid with the dataset I'm working with, and click the header of the column I wish to sort on, everything works perfectly. It sorts it hierarchically exactly how I would expect it to.What I want to do now is have the grid already be sorted when it is shown to the user. Is there a way to do this programatically? I can't for the life of me figure out how to do this, and clearly it's possible since the AdvancedDataGrid has this built in.[code]This appears to do something as far as sorting goes, but it doesn't sort it in the same way as clicking the column header. "startDate" is a property of an object in theDataSource by the way.

Following is the sample code. While I start editing either in optionId column or option column, the other rows of the same column are also get affected and reflecting the same value. But when I am editing in other columns it is working fine... Don't know the reason.

I am working on a Flex AdvancedDataGrid with a flat ArrayCollection dataProvider. The requirement is that when the root nodes is closed, the root row should show a subtotal data and when the root nodes is opened, not show the subtotal data.

I'm making an application where I display an AdvanvedDataGrid with one column with dates(in format DD/MM/YYYY) and another with datetimes (in format HH:MM). I'd like to sort dates according with the datetimes as well(just clicking in the header of the column), there is an examplen of the expected behaviour:
02/02/2011 | 10:42
03/02/2011 | 09:45
02/02/2011 | 11:45
03/02/2011 | 11:30

_currentDatosBusqueda is an arraycollection I receive from the Server (with the correct format of dates and datetime).

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 am using Flex 4, ActionScript 3.
I want to disable auto-sort. Meaning I want the sort to be executed only when the user clicks the column header, not when new rows are added to the binded collection or when values are changed.[code]...

Is it possible to completely remove the sort arrows on an AdvancedDataGrid header?
I know that you can kinda do this by using

and I even tried using

In flex 3 I have a hierarchical data structure. I would like to display the content of it in a tree. My problem is that I have nodes which data calculated from children nodes. How to structure the hierarchy to make automatic changes to those parent nodes, if their children's data changed? For example:
Every node has a warning flag. If some of the children warning flag changed to true, then the parent warning flag should change automatically set to true. A node integer field is the sum of the children integer fields, and if any of the children changes, the parent integer field "calculates" the sum immediately. Is there an easy solution wit good structuring changes happen automatically, or I have to make some custom functions?

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.

how can I refresh the displayed data in a Datagrid when the underlying ArrayCollection changes?
<nmoschitz:dataProvider>
<mx:HierarchicalData source="{arrCol_groupedData}"
childrenField="accounts"/>
</nmoschitz:dataProvider>
Calling a simple refresh (like with a simple arraycollection as a dataprovider, or with a refresh on the Grouping Collection) does not work. Also re-assigning the arrayCollection to the Hierarchical Data and then assigning this one again to the Datagrid does not work (even with calling invalidateProperties() or validateNow()).

I want to extend AdvancedDataGrid to show a Waterfall Chart in one of its columns.
To do that I already created custom cell render that shows bars as I need.
Now I have a little challenge: I have to pre-process data to show my Waterfall Chart properly. I have to do it before my grid is show. So, I assume that I have to extends AdvancedDataGrid and overwrite some methods.

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?

The dataProvider for my grid contains several objects. Some of which have a Number value, and some Boolean values under field 'value' (other fields are used in other columns).I would like to be able to render differently for each data-type, i.e. have a checkBox for booleans, and a label for numbers. Furthermore, I would like to be able to edit these fields differently, unchecking the checkbox for booleans, and using a numericStepper for Numbers.
Just FYI, I decided to go with AdvancedDataGrid, to take advantage of the styleFunction property, nothing more..Tried to used spark-states, which didn't seem to work as I'm using an AdvancedDataGrid. I'm not sure what the problem was.

I import XML data in order to fill an AdvancedDataGrid (using Flex 4.5). This ADG is correctly filled with the data, columns display the right information etc. etc.
I would like to summarize this ADG using
<mx:SummaryRow summaryPlacement="group">
<mx:SummaryField2 dataField="Cost" label="amount" summaryOperation="SUM">
</mx:SummaryRow>
But there is a problem! Indeed, the 'Cost' data are imported as 'Strings' and that is why I cannot do the SUM... I just get a nice 0 as a result! I would like to convert these data into Numbers, so that the addition can be processed. This conversion has to be done before filling the ADG I think.
I already tried to implement a custom summaryOperation but was unlucky...
public function calculateSummary(data:Object, field:SummaryField2, rowData:Object):void
{
var dataField:String = field.dataField;
[Code]...
The Alert always displays a void message, the data are not transmitted to this function I think
There is another thing: the user can insert new data in the XML dynamically and that insertion has to update the SUM result.

Is there some way in Flex where I can tell when all of the data has finished binding to my AdvancedDataGrid? I have a bunch of label functions that run and I need to a busy cursor while the grid gets populated. I then want to remove it when it's all done. And also fire another event.

I have an advanced datagrid, but I want users to allow to copy some lines they want. when I use the property editable they are allowed to select the text they need, but they also are allowed to edit this. How can I prevent that?
I want users to be able to select any text in the datagrid, but they are not allowed to change the value of the grid. They should only be allowed to select and copy (ctrl + c).

I need to insert a Box containing some text that appears between the grid header and main content and spans all the grid columns. I've been searching and experimenting (addChildAt()) but no luck so far. Is this possible to achieve?If not, is it possible to dynamically render the text in the header itself, below and spanning the column header text?

I will implement this myself if I can't find it but after 30 minutes of searching on the web I'm a bit surprised this doesn't exist. Basically what I need is a hierarchical list component like the finder app on mac. I want the same functionality as a tree component but displayed as each level having it's own list resulting in multiple lists that depend on each other.

When I get a collection back from the service tier, I create an ArrayCollection and apply a sort. When I add an item to the collection later on, the sort is still in place? It seems to be the case. I thought I was only sorting it once, not applying a sort that will stick??Here is the method for adding an item:
private function onAddNewClick():void
{
var fileTemplate:FileTemplateDetailDTO = new FileTemplateDetailDTO();

I'm trying to make a Flex Tree Component display the children of a sprite in a hierarchical way. Moreover, dragging the items on the FlexTree would resort and reparent the items. I have special Elements set as Folders. This would allow other elements to be added there as a children by dragging an element on the tree and dropping it there. I have a failed attempt which works, but breaks when I try to add folders. Basically, it fails at reparenting the items by dragging and resorting folders and that Does anyone know of a component or something which can do this, has anyone have created any of this or could anyone give me a clue?

I'm working (for my sins) on a Flex 3.3 project, which unfortunately cannot be upgraded to a newer SDK version at this stage, and have hit an issue with the custom hierarchical tree class (subclassing mx.controls.Tree) we're using. Excuse the spelling; the previous developer had a fear of dictionaries...
public class HierachyTree extends Tree
public function HierachyTree()
{[code].....
I'm using a solution somewhere between these two methods (basically, implementing ITreeDataDescriptor) in order to add live text filtering to the component, and it's working so far:
public class HierachyTreeFilteredDataDescriptor implements ITreeDataDescriptor
{
private var filter:Function[code]..........
The issue is that (with tree:HierachyTree) neither tree.maxVerticalScrollPosition nor the protected property tree.verticalScrollBar .maxScrollPosition updates when the search string is changed.I've tried calling invalidateList() and invalidateDisplayList() on tree — and calling invalidateDisplayList() and invalidateSize() on tree.verticalScrollBar — to no avail.

I'm using the Halo AdvancedDataGrid component, in which the default itemEditor for each column is mx.controls.TextInput.
For example, the data provider is:
[CODE][Bindable][code]............
If a String from the dataprovider Array is preceded by an asterisk - as is the case for banana in this example - the String needs to be surrounded by square brackets and be displayed in a grey colour.
I tried to do the following: [CODE]
A colleague told me about using the AdvancedDataGridColumn's labelFunction attribute. I tried that but was unable to do the following assignment (the id of the column is 'tag'):
[CODE]tag.itemEditor.htmlText = formattedText;[/CODE]
I get error "Access of possibly undefined property htmlText through a reference with static type mx.core:IFactory.I tried to both explicitly extract the TextInput itemEditor (like I did for the override set data) AND use the labelFunction, but I couldn't get both to be in the correct scopes.
