I did some work that used Flex datagrids previously. It was smooth for the users and developers alike.
In my current project, I have to implement the same grids but not using Flex / Flash.
I have taken a look at extJS and YUI but they don't seem to measure up.
Are there other packages I should be looking at ?
Is there a set of open standards technologies that I can use to achieve the same way of development as in Flex and Sivlerlight? I am talking about componentization, separation of concerns, rich graphics, states and effects . Please point out some tutorials and other resources if possible.
P.S. I KNOW that this is technically possible, so please do not respond by sending google search results or general JQuery tutorials. I've seen those already. I need to know how a Flex / Silverlight developer could design and implement an application in roughly the same way (imagine a rich HTML tag set, much like XAML/MXML, behind which stands JavaScript responsible for handling events and business logic.
I want to profile and unit test my application in Flash Builder 4 Standard. Adobe says I need to upgrade to the Premium version but I can't pay the money they want right now.Are there any alternatives for unit testing and profiling?
View 2 RepliesI've got a Grid whose GridItems contain another DataGrids. (The DataGrid are nested in the Grid). Now I changed the Grid's horizontalGap-StyleProperty to zero. But because there are several DataGrids in one GridItem, there is still about 5-10px spacing in between those DataGrids. How to get rid of these spacings ?
View 5 RepliesI have a DataGrid which contains a DataGridColumn with a textinput and DataGridColumn with a Button.The DataGrid is bound to some XML which displays values in the text box.When the button for a row is clicked I need to get the value out of the text box and save it into the relevant XML node.My solution was just to pass the id of the row to the button click event then loop over the rows until I find the id then just grab the text box value. Simple. However the only advice I can find on looping over the rows is via the underlying dataProvider, which is nonsense as the two aren't the same thing.

View 2 RepliesI have 2 advanced data grids, one above the other. They both have the exact number of columns, and pertain to each other in the same way. But each is showing different data, which is why I split into 2 grids. However, on each one you can resize the columns, what I would like is to make it so that if you resize a column on either datagrid the same column on the opposite datagrid resizes as well, so they are both always lined up.
View 1 RepliesI want to use one data source (e.g. an Array) for multiple Datagrids that have different filterFunctions attached and show different columns.First, I thought I use a very straight forward apporach:create the Arraycreate an ArrayCollection for every DataGrid and set the "source" property to the Arraycreate the DataGrids and set their dataProvider property to its designated ArrayCollectionSo now. every ArrayCollection can have its own filterFunction, sort state etc. but there needs tos are dispatched and I have to call itemUpdated manually on each of the ArrayCollections. While debugging into the code in order to get a deeper understanding for Flex, I tried to figure out, what this misterious "itemUpdated" method does, especially as it notes in the adobe documentation, that, if no "property" is given (e.g. it is null), a simple "refresh()" will occur.
I did not find any calls to "refresh()" in the whole debugging (and I went down the framework whole as deep as possible (btw: lots of funny comments right in the code :-) )he only thing I could find was a CollectionChangeEvent getting dispatched with a PropertyChangeEvent in its "item" property. Which was of the kind "UPDATE" (and not, as I would expect "ADD"). When trying to dispatch that event manually, it never worked (e.g. the datagrid did not update).
is there a way to control the text positioning in the datagrid cells in Flex so that all text in subsequent columns align on the same rows?
View 2 RepliesI have multiple datagrids with about 10-15 columns total. I have a numeric sortCompareFunction for each column. At the moment, I have a separate function for each sort compare I do....each does the sorting numerically. I'm guessing I could condense functions sort1, sort2, sort3, etc into 1 function but I can't figure out how:
private function sort1(obj1:Object, obj2:Object):int{
var value1:Number=(obj1.zip==''||obj1.zip==null)?null:new Number(obj1.zip);
var value2:Number=(obj2.zip==''||obj2.zip==null)?null:new Number(obj2.zip);[code]...............
I've got a client who has a list of items on a Datagrid. When the row is clicked, it sends the user to another page with details of that item. The client wants the rows to act like HTML links, where the color is purple when the link has been previously visited and its normal color if the row hasn't been clicked in the past. I've accomplished this with item renderers and SharedObjects. The application loads the visited ids into an array on start and the item renderer colors the individual cells if that row had been visited.
The issue here is that the client also wants the text color in the rows to turn white when the user rolls over the row. Because the item renderer sets the color, it doesn't respond to the default stylesheet for the datagrid. I can make it turn white on rollover of an individual cell, but we need the whole row to do it. Is there a way to trigger a function in all the item renderers in the row, or is there a better way to accomplish this?
I have a flex application in which I have a TabNavigator with multiple tabs and a datagrid in each of those tabs. I have bound s single array of data to each grid.
What I want to do is to bind each grid with a particular set of data in that array i.e. to distribute array contents among grids based on data type. For example items starting with letter A could be displayed in first grid, B in second, starting with C in third and so on. Hence you can say alphabetically distribute the data on different grids. The problem is that the data will be added randomly by the user.
To make one data array for each grid is not an option (due to design restrictions).
Is it just me, or do flex MX datagrids sort in a case sensitive manner be default? That is, they'll sort like this:
I know I can give a datagrid column a custom sort function, but do I really have to do that for every column in the app?
So this is a bug in a legacy app- updating every single grid to spark really isn't an option (if that's even a fix). Am I missing some obvious way to change the sorting pattern for an entire grid?
Im using Oracle, BlazeDS, Java and Flex. I have a list of objects displayed in a datagrid(Lets call them Main-objects. Each of these objects have a set of UserComment-objects associated with them(One-to-Many relation in the DB). These comments may come from two different "types" of users, distuingished with either a 1 or 0 in the UserComment-object's "userType" field. Each time the user selects a Main-object in the datagrid, the UserComment's related to this object is displayed in a separate datagrid below.Based on the introduction, i want to separate the UserComment's into two separate datagrids (one for each user-type), instead of the one i have now. So my question is: What is the best approach for performing this task? What is the best way of separating the UserComment's into two separate data grids based on the value of the "userType" field?

And also how to print the multiple pages when I have large data in advanced datagrid.
View 1 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.
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?

View 1 RepliesI'm looking for a flash script/library to capture video and audio from a webcam and then somehow get a saved flv to my encoding server. I'm not looking for something that will host the videos for me. I just need something simple to capture and then upload. I really want this to be open source and free.
I've done a fair amount of searching and it seems that most of what i can find is either a full blown service with hosting, or the red 5 suite. I've been trying for a day to get something going on with Red5, but honestly I haven't done any flash or java development in over 6 years and this seems way too complicated when all i really want is a flash object i can stick on a webpage.
I have an air application that loads a swf ( built in flex ) , this swf loads moduls and basicaly my air application is a testing environment for this swf .
when i run it in flex environment ( eclipse ) it runs fine , when i run it from my programs ( as an air program ) it gets stuck , what i was thinking is that it has to do with security issues because it gets stuck when my main swf try to loads the moduls .
I'm building a Flex/AIR application that connects to a remote server, the URL of which changes depending on the environment (development/production, and possibly others). For now, this URL parameter is hardcoded in my root application MXML file but it means I have to change it everytime I build my app for a different environment.Is there a way to externalize such a parameter so that when Flash Builder automatically builds my app (in development mode), it uses the development URL
View 1 RepliesI have been trying to find solutions to this everywhere and cannot find any concise, clear instructions on how to set up Flex and Actionscript properly on TextMate. That is, I have the bundles but in terms of setting shell environments etc so that you can compile with ANT, find documentation for keyword (Reference Doc) within the app. For the latter ,when i try and do that it says no documentation found.
My shell env stuff is as follows:
TM_FLEX_PATH /Applications/Adobe Flash Builder Burrito/sdks/flex_sdk_4.5.0.17689 TM_FLASH_HELP /Users/doronkatz/langRef (this is where i have the as doc zip file i downloaded)
Are there any differences implementing Flex application security in a clustered Java environment (such as Oracle Application Server/OC4J or a JBoss cluster) vs a single application server environment? (And/or does it depend on the specific environment software?)
What considerations are there in a situation where you need to authenticate with LDAP (AD) and store user access information in a database (ex. USER table containing username + permissions/roles info)? Any differences between Blaze DS and Granite DS?

i don't know how to say that in technical terms. and i think this is the reason to why i cant get good answer from Google.i have xampp on my local winxp machine. i use it for developing websites locally then upload these files to my clients shared hosting accounts.
the problem that in 2 years i have always found differences between how xampp works and how the web server work.some code work locally but dont remotely and the opposite. also flash behave differently on xampp than the remote web server.is there is a way i can get the server configuration and use it with xampp like get the server php.ini and use it with xampp?

View 1 RepliesI'm trying to test a custom Flex 4 skinnable component, using the FlexUnit UIImpersonator class. If I run my tests from a FlashBuilder Spark only project everything works fine. If I try to test from a project with the mx component set on the classpath I get a "getElementIndex not available in non Flex 4 projects" error.Can I unit test spark components in FlexUnits visual test environment while still having the mx component set on the classpath?
UIImpersonator delegates it's method calls to a "testEnvironment".The implementation used for this "testEnvironment" is decided by the VisualTest EnvironmentBuilder class and the FlexEnvironmentBuilder class. If the FlexEnvironmentBuilder class can find the "mx.core.Container" on the classpath it returns a MX environment, else a Spark environment. Only the spark environment has valid implementations for Flex 4 relevant method calls on the UIImpersonator - like the addElement method.
for some reason, whenever I dynamically load a swf on a $(document).ready() by writing to a div, I am unable to make javascript calls to the browser. Specifically, all calls to the browser return "null". This does not occur when embedding the swf normally on the page load, but I would like to prevent loading of the swf until a specified point in time.
What the heck is going on here? Is there something special about dynamically embedding a swf that prevents the swf from talking to the browser? The methods ARE called (I've proven such by showing alerts), but all return values to any function, regardless of type returned, shows as null when it gets to flash.
