This 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 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 Repliesi 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 RepliesI 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've got a Gridcolumn in a Datagrid (Spark). The Column's dataprovider is a Number value that gets updated via Binding.Now, without an item renderer the cell displays the correct values.If I set an item renderer, I can't access the values in this renderer.My renderer looks like this, so nothing really do here (for now) but to trace the value, but the value is always NaN.
<?xml version="1.0" encoding="utf-8"?>
<s:GridItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark" width="100%" height="100%" >[code].......
without the renderer, the column displays the correct values, so apparently the DefaultGridItemRenderer works fine.As requested, here is my Datagrid;
<s:DataGrid id="dataGrid" dataProvider="{_listItems}">
<s:columns>
<s:ArrayList>[code]..........
_listItems is an ArrayList with instances of a model class, which has (amongst others) a property called change of type Number.
I have a DataGrid whose dataProvider is an Array of int Arrays (each with different lengths). Since each row has variable size (and I want to display all the data), I decided to extend DataGridColumn and overwrite the itemToLabel function to be able to display the data. The problem is that I also need to display the data differently depending on the int value.
I believe the only solution is to write an itemRenderer, but the only input the itemRenderer.set(data) function receives is the entire int Array. I believe I need either the exact string returned by itemToLabel or the column index of the cell the itemRenderer is for (to basically do the same parsing I implemented in itemToLabel).
I 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 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 0 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'm doing an AIR app scheduler to load data from a .txt. I'm able to trace the data in flash but how do I put those data into flash components (maybe datagrid? Maybe something that can let the user delete part of the entry of their schedule in the scheduler. For example if they wish to delete entry 5 of the scheduler, what should the code for the app be? After displaying the code in the app via flash, the user will be able to delete the fifth entry in the scheduler, or something similiar to this idea. How can I achieve that?

I was wondering, how can I take data out of a datagrid?
I know how to put data into it, and to get it displayed, but basically, I want to take selected data out of it, so I can send it through a URL so that I can get my code to mess around with it.
Can I move/copy values from a DataGrid to another without using the DataProvider of the first DataGrid?

I have a custom dataGrid that acts more like a 2D list (if that makes sense at all). I am dynamically creating the columns and recreating the dataProvider to suit my needs. While debugging I can see that I am creating the columns and setting them to the dataGrid and creating and setting the dataProvider, but for some reason I am able to see the dataGrid and the columns but not the data.

I have a form that consists of two data grids and a button. Datagrid 1, "myStaticDataGrid", has values I have added for the user to select from. I want the button's click event to send the current selection of myStaticDataGrid to the second datagrid, "myDataGrid". I have been able to accomplish this if I use a text box and a datagrid but I am having trouble finding the right syntax to grab the selection data from myStaticDataGrid.This is my attempt using the two datagrid approach:
<s:Form id="myForm">
//The values from this grid are determined once the button is clicked.
<s:FormItem id="myDataGrid">

datagrid won't display data. Evidentally it captures the correct no. rows because the scrollbar appears. I've got an amfphp returning a resultset from a db which contains too much info and doesn't correspond with my datagrid so I'm trying to copy out whats needed to a ResultCollection (if it all looks a bit mad then it's because I'm new to this and still finding my way around).
Debug tells me there actually is data in the ResultCollection but I'm really struggling to find out why it wont display and will be really. I've searched the web for AS 3 examples of coding a datagrid - all pointers welcomed.

I've scripted a connection to PHP that gets data from MYSQL and outputs that into a datagrid.When I encrypt the swf with Ameyata SWF Encrypt 5.0, and upload it to my webhost, it looks fine. I can click the header of the datagrid (that sorts the data), but when I click on a field of the datagrid, it just freezes and my datagrid is not usable. I'd have to reload the page in order to do something with the datagrid again. But the problem with the field remains.It works when I'm not encrypting the swf.URL...
View 2 RepliesI have successfully created a datagrid and added columns to it using addcolumn column command. I have added also data to it using my_datagrid.additem command.
How can I retrieve the data in the datagrid? note that I am not talking about clicking on the datagrid and selecting a cell. I want to read ALL the contents in all the columns.
I would want to print out all the data inside my Datagrid which were populated in flash AS3. Taking into consideration that my datagrid has horizontalScrollPolicy and verticalScrollPolicy activated, how do I print the whole information?This is the closest sample code I'm looking for, but I had alot of errors when I tried to use it, maybe because it is in AS2 & i convented it wrongly...The problem is it prints nothing in the 1st page and some weird layout in the 2nd page.[URL]

I have a multi-column DataGrid that I've populated only three of the seven columns with data. One of the columns are editable. The other three are not editable. What I intend to do is have the user enter data into the editable column. Once the data is entered, The other three empty non-editable columns will populate based on calculations done to the value in the editable column.The problem is that when I enter data into a row of the editable column, the data isn't being reflected as entered until I try to add a new row. Is there any way to get the value being entered into the cell right after it is entered without the user having to enter a new row?
