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 have an actionscript function which is supposed to launch a panel and then fill in Networktopology data inside it.As, network data is too large that it consumes much time and makes browser hang!Even I tried to display busy cursor which also stopped spinning when data was being processed.How can I ensure processing large amount of data does not hang the browser.
View 3 RepliesAs I know. Flex/AS is single threaded.I want to write an application that talking to server side, also display the data streamed from server.Since Flex is single threaded. I am not sure how could I do this.Better not involve something like "implement your own multi-thread model"
View 1 RepliesI 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.
View 2 RepliesI 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?
<mx:AdvancedDataGrid id="dgAssetStatus" width="100%" height="85%" initialize="gc.refresh();">
<mx:dataProvider>
[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.
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 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.
View 1 RepliesI 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?
View 1 RepliesAll I want to do is have an input text box where the users type a number, then Flash to perform a simple calculation and then display the answer on screen. For example; output = input *2 so if the user entered "5" the value displayed on screen would be "10".
I found this tutorial which is exactly what I am trying to do: [URL] but cant get it working correctly for some reason and just gives a "NaN" result (looks like an old version of flash)
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.
A groups of friends are working on a little game that would listen to the microphone as part of the interaction. We've tinkered with processing and flex. What we'd like to know is if anyone has succeeded in:
recording from the microphone using a web app
performing an FFT on this microphone data
In the case of flex, according to the docs "Because sound data from a microphone...do not pass through the global SoundMixer object, the SoundMixer.computeSpectrum() method will not return data from those sources."[1]

I've been working with a 3rd-party multiplayer engine for a game I'm developing. A lot of messages get sent during certain times (loading, etc) to the point where it is possible that multiple messages may be sent per gameloop. To solve this problem, I am attempting to create a delayed message processing scheme. this function is invoked every time a new message is received:
Code:
// called by the Client
public function PushMessage(gameMsg:GameMessage):void
{
messageQueue.push(gameMsg);
}
And at a point in the gameloop, I want to process these messages and clear the message queue. The only problem: there is no assurance that the messageQueue won't be modified during that time. The messages in AS3 are basically interrupts (possibly overlapping), and I can't find any way to temporarily disable event dispatching for a specific EventDispatcher-derived class.
So at this point I can think of only two options. The first is to write a mutex using a Boolean and setTimeout. I do not want to do this for obvious reasons (bad! BAD!). The second is to give up on a delayed processing model.
Is there a way to process a picture > 4096 x 4096 px in pixel bender? Or any other technique?
View 3 RepliesI'm creating some image uploader in Flex with client-side image processing. Processing consists of two steps:
1. Resizing (solved)
2. Converting resized image (represented by ByteArray in PNG32 with alpha-channel) to gray-scale PNG with bit-depth = 2 and no color-palette. Is there any existing library that is capable of second step? Something like libpng for C++, maybe?Edit:It seem I stumbled upon rarely encountered problem. However my descision was to create an AS3 class that is capable of converting bitmapData to 2bit grayscale PNG. I used standart PNGEncoder and PNG format specification (which is not so good as I expected) as basis.
I'm using Flex 4 and I need to render the data that resembles HTML Table with row span in a Flex component.My inclination was to use a DataGrid but I believe that rowSpan is not supported for that component. I looked at the AdvancedDataGrid but the user does not want to have a tree-structure in any of the columns. Looking to see if there are any hints/tips for modifying the DataGrid or AdvancedDataGrid to produce an "HTML Table with rowspan" look.
View 1 RepliesI have implemented drag and drop between 2 AdvancedDataGrid, but the default behaviour from Flex displays the row data during the drag using the grid item renderer showing all 5 columns.
Instead, I would like to display an icon / image or my own custom item renderer during the drag and drop.
When I test my deployed app in a browser the popup window continues to be displayed even after it should be closed. Everything works as expected when debugged in Flash Builder 4.
Following is currently what's happening: the request is sent to my restful web service, which processes the request, (seemingly) the ResultEvent is called which in turn dispatches the profileEvt dynamic event that changes the view state. However, the popup window does not get closed and the applet gets 'stuck.'
Below are the flex applet web service event listeners/handlers:
webService.addEventListener(ResultEvent.RESULT, function(event:ResultEvent):void
{
var rawData:String = String(event.result);
var profileEvt:DynamicEvent = new DynamicEvent("profileSaved", true);

Is there any way to detect if AdvancedDataGrid itemClick event is actually caused by the user dragging? I'd like to take action on click, but ignore drag.
View 1 RepliesI have an AdvancedDatagrid, whose dataProvider is an ArrayCollection that contains 1 row of displayable stuff.Flex continues to display about 6 rows, the top one filled, the rest blank.I've set the rowCount="1", with no luck.
View 3 Repliesafter multiple Selection in a advanced datagrid, I want to check if the clicked row, was already selected. Anyway my idea below (in the nested if clause I want to check if the newly clicked item's processing data is already in the added Array Collection) is not working, but I assume there must be a better way to differiante if an click was made on a already selected row.
model.processingData = out;
if (model.selectedIndices.length > 1){

I would like to add new row on the fly (runtime) to my AdvancedDataGrid.I can add it to the data model, but couldn't find a way to make the table render and show the new row.What i am seeking for is to create an effect of expandable item, where clicking on row will show "additional information" (like a drawer) and clicking on row expand button will reveal it's children.I saw examples of this for dataGrid (http:url...), but not for AdavancedDataGrid.Only way I found to do this is to add a new child and use openItem, but this cause the other children to be visible as well.

I've got a subclass of AdvancedDataGrid showing a tree-like data structure. How can I, given the index returned by calculateDropIndex, get the item at that index? After reading through reams of code, it seems like the least terrible way is:
var oldSelectedIndex:int = this.selectedIndex;
var mouseOverIndex:int = this.calculateDropIndex(event);
this.selectedItem = mouseOverIndex;
var item:* = this.selectedItem;
this.selectedIndex = oldSelectedIndex;
The other option seems to be tinkering around with the iterator property... But, judging by the way I've seen it used, that will get pretty harry pretty quickly too. So, how can I get the item at a particular index in an advanced datagrid without going insane?
Is it possible to use a renderer for for a treecolumn in an advanceddatagrid and still keep the hierarchal functionality? If I use a renderer provider I lose the the arrow for the tree dropdown.

I've a problem, I'm using an AdvancedDataGrid. It loads about 3000 records with about 20 columns. I constantly get Flex execution timeout because the grid executes a lot inside LayoutManager. How can I make it asyncronousely or faster at all?
