I have flex advancedDataGrid (could use dataGrid if that works better, though i like my meta-column headers), and i want to have a component popup on top of a selected row.
The problem is, i can figure out how to reference an actual rendered row of a datagrid (rather than an item of the dataprovider) in order to get its position on the screen.
how to access a "row" of a datagrid, or at least get its position?
How to populate a flex datagrid from an Arraycollection without specifying DataGridColumn's individually. Is there any custom datagrid available where I can pass the datasource arraycollection and see the data populated in the output. Without knowing the structure / bluprint of an object is there anyway to find how many member variable that class have?
View 2 RepliesI have a custom <mx:DataGrid /> that is updated with data from a ColdFusion server every 60 seconds. I've noticed that every time the DataGrid updates and redraws the scroll position is reset to the top.
Is there a way I can preserve the scroll position for my DataGrid?

View 1 RepliesHow does one find the position of a child movieclip within a parent movieclip relative to the stage? Whenever I refer to the position of the target movieclip, it gives me a number of what I'm not quite sure it refers to. I want to know the position of a an object as it is seen drawn on the stage
View 5 RepliesI'm often finding a need to get a stage-relative position of objects in my game, which are often buried several layers deep as children of children of children, etc, often with differently scaled/moved/rotated parents. The position i want isn't quite relative to the stage, but a main holder object i have on it called lvlHolder (see code below). I wrote a function to deal with it that recurses up the display list, accounting for each object as it goes, to get a global position. It's worked so far, but one thing it doesn't account for is rotation. I'm finding a need for that now, and i'm not sure how to account for rotation of objects, to rotate offsets from them,
My function is below. how i should enhance it to accomodate for the rotation of each parent object? Also any tips on optimisation would be good, as i'm using this a LOT (roughly twice per frame, per object, for physics calculations) I'm also wondering, in similar situations i've seen something related to transform matrices used

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?

- 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.

For 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 am attempting to style the headers in a flex datagrid and I keep getting the warning:
Type DataGrid in CSS selector 'DataGrid' must be qualified with a namespace
What does this mean? I have gone through a bunch of tutorials and none of them have worked. It seems like changing a the colors in a datagrid should be relatively simple.
Here is a code sample:
<mx:Style>
.headerCustomStyle

in Flex I have something like that: [code]and dg is ALWAYS pointing at DataGrid (even if dg1 has name DataGrid_test and dg2 = DataGrid_test2) and finally action is made on my first DataGrid (DataGrid_test).[code]and search still points at ColorColumn :/ My problem is really easy- I just want to pass to search different dataGrid on each state.But still I don't understand why it doesn't work. My search function uses algorhitm Boyer-Moor for searching through dataGrid.dataProvider for some text. If it find something then it is pushed into new array and after passing whole dataProvider I colorize rows with searched word.

Recently I configured my BlazeDS to use Array instead of ArrayCollection for performance reasons. Additionally I adjusted my templates to generate Array properties.Everything wen't fine. All except one function that causes TypeError: Error #1034. These are being thrown before the result callback is called. It claims to have problems casting an ArrayCollection to Array. I removed the generated types to make Flex use Objects instead, but these did not contain any ArrayCollections. My question now is: How can I get the stack-traces of errors thrown in event-handlers? I allready added handlers for unhandledExceptions in all of my modules and they are called if errors occur in code triggered from user-interaction, but they don't seem to be able to catch stuff thrown by event-handlers.How can I track these Errors?

Since Flashbuilder does not support WCF over https, I am considering to use weborb remoting as alternative, but not really sure how flash is going to know weborb location, if they are sitting on different servers.

View 1 RepliesI have the problem that when I use a component from an existing Flex Library in my AIR project, the values that should be loaded from the appropriate locale .properties file are not loaded. The values are always null.
I am using Eclipse and have created an AIR project that refers to the existing Flex Library (of which I have the source code). When I use a component from that library it calls the following code:
var _resourceManager:IResourceManager = ResourceManager.getInstance();
var res:String = resourceManager.getString('resources', str, params);
"str" and "params" have valid values but res is always null.The properties file is located within the assets directory of the Flex library. I am deducing that the properties file is not being loaded (for some reason). This Flex library works for other Flex projects so it has to be something about the way my project is set up.
I have my compiler settings set to: -locale en_US Is there something special that AIR projects need to do to ensure that they can refer to properties files?
