I'm currently working with the OLAPDataGrid component and got stuck at a relatively simple task: I want to style the last row of the grid differently from the rest, so my cell item renderer needs to know whether he's rendering the last row with content in the overall grid, including those rows currently not rendered because they are outside the visible grid space. AdvancedGridListData's rowIndex property only gets me the row index of the renderer relative to the range of visible grid rows, i.e. when I scroll down the grid, a data item with an index greater than 0 gets the rpw index = 0.
View 2 RepliesI stumbled upon the need to find out (inside Java code) which files are dynamically loaded by an SWF-file. Is there any possibility to get a list of paths of every object referenced inside? I tried out some libraries without proper documentation and gave up. Maybe there is an external tool which can be accessed by Java via command line?
View 2 RepliesI tried with flex and java in the backend. In this, I am able to upload files till 100 MB using remote object (blazeDs) where we will read the file as byte array and send it to the java method. If the file size exceeds after that, then I get the run time error in IE.

I am using a spark list control to display certain items with my custom Item Renderer. I am trying to achieve the following: (1) show a separating line between rows in my list control (2) even when not a single row has been added, I want a horizontal grid lines to be displayed in the background
I am not sure whether (1) and (2) can be achieved in one go. I can solve (1) by modifying my item renderer to have a border, I guess. But I want to know whether there is a better or more conventional way.
I'm trying to code the snap to grid functionality. The dragged object should snap to the grid if the distance between the object bounds and a grid line is less than 5px. I found a way to do it if the object's rotation is 0 but it doesn't work if I rotate the object. I need a different approach. Can you point me into the right direction with the algorythm or any source code?
View 3 RepliesI have to populate an Advanced Data Grid which have the following fields: Continent->State->Society-->Actual Value-->Estimate Value I want to simulate a financial market so i have to change some of the values by asynchronous request from an HTTPService; If necessary i'll post the .as file, but it is generated automatically by Flex Builder.
Here's the code of the client side Flex/Air application:

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.

View 1 RepliesI am working on a grid example in flex using advanced grid control. I know we can easily group data by specifying the field name. At the group node level, other than the gorup name I want to be able to show data in the rest of the cells ( calculated data ) and I am looking for some dataRowBound event or similar to be able to hook some data in it.
