Flex :: Implement Paging In Datagrid?
May 2, 2011i want to implement paging in flex datagrid, i am using this code. In Asp.net we can implement paging by setting property of datagrid, is there any such property for flex datagrid?

View 2 RepliesHow does paging work, must Flex load in all the database records to determine how many pages to generate? Let's say I have a table with 10,000+ records and want to split it into pages of 10 records per page into a datagrid component. Does Flex load in the complete 10,000+ records, or just some of them? I would like to use PHP and AMF on the backend.
View 2 RepliesThis essentially means that as the user scrolls the DataGrid only the data needed is requested and displayed (essential for m app as users could have 1000's of records). I was wondering if anyone has any examples of doing this with a Flash DataGrid rather than Flex as my project is pure AS

View 1 RepliesI am trying to find an easy and robust way to override the default layout of DataGrid and populate its values in a left-right fashion. To illustrate:My data model is an array of: {a: xxx1..n, b: yyy1..n, c: zzz1..n}The default DataGrid component will lay this out as:
a b c
xxx1 yyy1 zzz1
xxx2 yyy2 zzz2
xxxn yyyn zzzn
etc.
With "a", "b", and "c" as the headers, and x, y, z being their values for each object in the dataProvider.Now I want to lay this out horizontally like so:
a xxx1 xxx2 xxxn
b yyy1 yyy2 yyyn
c zzz1 zzz2 zzzn
I've searched around for an answer but haven't hit on anything. Perhaps I'm just using the wrong keyword searches...Regardless, if anyone knows a solution to this, be it as mundane as a property setting I've somehow missed, or a 3rd party component, etc.
ps: Eventually, this must be entirely tab-enabled and cell-editable. If you have an esoteric solution involving a multi-field itemRenderer, please keep this in mind. I mention this because I have attempted such a solution and have failed to penetrate DataGrid's Unfailing Field of Tab Vitiation (ie DataGrid seems to override tab functionality inside its itemRenderer, forcibly setting focus to the next renderer/editor).
I need to display set of images in horizontal list. The list needs to be controlled with next and previous buttons. Moreover I need to display paging showing no of images per page below the list.
View 1 RepliesI'm implementing an image gallery which presents assets as equally sized boxes that are forming a grid. I thought that I could easily achieve that by using the spark.layouts.TileLayout but unfortunately I have some additional requirements that I'm unable to implement with it.The general principal should to be to present as many boxes as possible within given space. The entire layout of the application is liquid and depends on the user's screen resolution.[code]I don't know the RequestedColumnCount or RequestedRowCount in advance as they depend on the available space, so the above code layouts all elements from left-to-right and then from top-to-bottom - which is as close as you can get from what I really want to achieve.This list of boxes should be cable of rendering fake paging. In reality it means that if the last visible row does not entirely fit the available space it should be moved to the next page.
To give you an example let's imagine that we have a list of 10 images. Each one is 10x10 px but my screen resolution only allows me to fit a grid 35x35 px. This means that one page is only capable of presenting 9 images in form of a 3x3 grid (as 5 px is not enough to present a full image). The 10th image should be then transferred to the second page.This is obviously not happening automatically with the code that I've pasted above as the TileLayout allows for displaying partially visible rows (in a form of a vertically scrolled list). I was wondering how I could achieve the behavior described above.If the above description does not sound logical please let me know so that I can adapt it (or include more details).
I want to have some sort of a list, which will contain movieclips (or thumbnails) ... is this possible to implement using the List component or DataGrid component?
View 1 RepliesI retreive data from an XML file. (title + link on title to external site). The amount of titles (with link) can vary. What I would like to do is display 10 titles at a time with, if more than 10 records, a next 10 button (and previous 10 button).
Showing all the records is not a problem just as showing the first 10 records. But my 'next' button is not working...
Hereby my code:
var item_spacing = 15;
var item_count = 0;
var i = 0

I've added an eventListener to the COLLECTION_CHANGE event that is fired when the grid is finished resorting the items in its dataProvider, after the user clicks on a column header:MyType (myDataGrid.dataProvider).addEventListener(CollectionEvent.COLLECTION_CHANGE,onDataGridResort);
View 1 RepliesI am working on a problem since a week soon, but I still couldn't make it work as expected. I have a DataGrid which has HBox with a CheckBox an a Label as itemRenderer (see Code below). When I tap in to the Cell the standard itemEditor pops up and lets you enter the content of the label. Thats the standard behavior. I works fine except for 2 problems:
If I enter to much text, the horizontal srollbar pops up, and the cell is filled with that scrollbar. As you see I tried to set the horizontalScrollPolicy to off, but that doesnt work at all... I tried to do that for all the different elements, but the failure is still existent. When I have filled more than one row, there is an other mistake happening. If I tap on a row, the datagrid selects the one below that row. That's only if one line is already selected. If I tap outside the datagrid and then, tap at any row the itemEditor of the right row will show up... Is there anything now wright in the setup of my set data method?

How to turn Flex MXML DataGrid into something like Horisontal DataGrid? (may be some how with Flash builder 4?)
Keeping all stuff DataGrid has like eating data from data provider sortind dragging - droping items etc
I have two datagrids:
- Division
- Members
Both have single columns. Selecting one item from Divsions datagrid should display members of that Division in the Members datagrid. But following code has some problem and Members of a particular division do not show up when respective Divsion is clicked.
Following are some snippets of the related code. Hope someone can spot an error in it.

i need to use large list of locations in text field round about 5000 to 6000. i have done that but the text field doesnt display data when reaches more than 3000 i think (below it its working fine), i need to cater this prob, maybe it can be done through paging
View 0 RepliesFor poor performance reasons, the DataGrid will cache checkboxes and reuse them for different rows. If you have 50 rows, it won't create 50 checkboxes. It will create as many checkboxes at are visible, plus a few more for padding, and then reuse them as you scroll. This is why you need to explicitly manage their state. How can improve it ? How can fixed checkbox value ? i used checkbox like below But checkbox doesnot remembering the values

I have a Flash Datagrid component being populated by data from Robotlegs services. However as the datagrid needs to show more and more rows of info I need to implement a way of loading the data as it is needed. Ideally this will be as the user scrolls down the list, I have seen this in Flex examples but I could do with a pure AS3 solution.
Here is the Flex example: [URL]
I am writing a Flex application for use on a private intranet with no external Internet access. I want to use Google's 3D Maps Flex API, but it must be connected to the internet to download map tiles on demand.
Is there a way to locally cache the 3D map tiles and data so that I can run this app without an internet connection? And if not, is there a 3D GIS that supports Flex integration and allows for a local map cache?

View 1 RepliesI have a function that restores all of the default settings of my application. This process can take a bit of time, so I would like to implement a "Please wait..." modal popup to let the user know that everything is alright and the program hasn't frozen. Once the function completes its task, I'd like for it to remove the message, and resume normal behavior.

View 1 RepliesI've written a Flash (Flex) client connecting to a back-end server to exchange data. I've also written my server from scratch, and it serves two purposes:
(1) Web (HTTP) Server- By default listens on port 80
(2) Socket/Application- Server - By default listens on port 443
Just FYI, both servers run in the same process space, for convenience reasons. They are not expected to handle massive loads, so I'm fine with that. As soon as the Flash client is served to the browser from the HTTP socket, the client attempts to open an XMLSocket to the Socket/Application server. I now want to implement HTTP tunneling, so that my client can connect to the Application server even if the user is behind a firewall. I do not want any external servers involved (proxies etc.) - simply use the servers I already have.
My questions:
(1) Is it better to use port 443 for that? (does it better fool firewalls?)
(2) As far as I can see, what I am required to do, is just ensure that my actual application data is simply encapsulated in an HTTP structure (preceded by a dummy HTTP header), both from the client and server sides. Is that so or am I missing anything here?
(3) Do I need to keep hiding/encapsulating my data every message I send through the socket, or can I just encapsulate the first message when opening the connection?
I am considering creating a website with the complexity of Facebook that should be able to scale into the millions of users. My question is: Is there any reason not to use Adobe Flex for such large project apart from the obvious point of requiring everyone to have Flash installed and not having to rely on Adobe? In my view Adobe Flex would reduce the server load for Facebook, because more of the work could me done on the client side.
View 7 RepliesI have a List component from which I'd like to be able to remove items using drag & drop, but without having a specific target. If you use the mac, the behaviour I'm looking for is something like what the Dock uses; when you drag something out of the bounds of the control it should get an icon that indicates that it'll be deleted (OSX uses a cloud or something?) and then if you release it it will be removed from the list.

View 1 Replieswe have one application where we are pulling some confidential information from one of the product design tools. So we have used HTTPS as the channel and also we are encrypting the Request Parameters and Some data before we sent it to Web Services.Everything seems OK.But when we gave the application for Security auditing they found we have hard coded the encryption key in source code. They have used Sothink SWF Decompiler to look into my SWF file. They caught the key and raised concern over it.
We have developed this application using Flex 3(SDK 3.4). Is there any best way to use Secret key without being hard coded in source code. If anybody come across this kind of problem, please let me know. use the secret keys in SourceCode without being Hard coded.
Here is my sample code:
var currentResult:String = "";
var strDataToEncrypt:String = "";
