I want to know which header the user clicked on to give the currently sorted view. Is there an API in flex framework that I can use to achieve this? Hopefully I can get back a column index so I know how it is currently sorted.
View 1 RepliesI use a flex mx:datagrid. I can set the headerBackgroundSkin to specify a skin or a picture to be displayed in all datagrid column's headers and it works just fine !
The problem is I can't find any way to specify a custom skin for the currently sorted column (doesn't matter if the sort is asc or desc, this is just to show the user which column is currently sorted).
I also tried to create a custom headerRenderer for each column but it is quite complicated and doesn't work very well.
I have been looking for the solution for a while but I can't find a good approach to do it. It sounds like a very basic need for me...incredible it is so complicated to achieve with Flex !!
I noticed someone was looking for the same thing few years ago but without success... [URL]

View 1 RepliesI have a column in a data grid that has the values of "Monday", "Tuesday" etc, as varchars, and I wanted to know, how do i sort the column to be in the correct order.

I am assuming some sort of itemrenderer, but anyone got a snippet of code to illustrate how this would work?

View 2 RepliesI am looking into achieving below two features in a flex grid( or advanced grid).
1. merge column headers ( as in group just the cells in the header row ).
2. add multiple ( say 2 ) headers to the grid.
I have a Flex Column Chart that has a range of 0 - 6 on the y-axis. I have added the following block to change the default colour of the horizontal grid lines to black.
<mx:backgroundElements>
<mx:GridLines>
<mx:horizontalStroke>
[Code]....
This works fine for all but the horizontal grid line at the top of the chart (at y=6). If I change the maximum value for the y-axis to something different then this new max doesn't have the formatting applied (but all the others do).
how do I get the top line to be black like the rest of the grid lines?
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 am trying to figure out how to open a pop up window in my Air application, in a secondary Window, instead of the main application window.I am using the ReusableFX components, which include a custom DataGrid with filtering and other capabilities. The filtering feature displays a pop up window via PopUpManager when you click on the top of a column in the grid.
PopUpManager.addPopUp(this, FlexGlobals.topLevelApplication as DisplayObject);
The problem is that the pop up window opens in the main application - I am assuming because of the 'topLevelApplication' reference.So, I need a way to open this window in the current Air "s:Window". I am assuming I need a way to walk up : this.parent.parent or this.owner.owner - though I have tried that and it did not seem to work (it said null reference).OR, is there a way to get the current top most window / component (NOT the main application / window)?
Update:I decided to create a new project for the component, and add in the Air libraries. Now I am able to access the "NativeApplication.nativeApplication.activeWindow" call. That gives me the correct Air window. However, it does not seem to be working:
PopUpManager.addPopUp(this, NativeApplication.nativeApplication.activeWindow as DisplayObject);
My popup does not appear. I am assuming because "activeWindow" is not actually a DisplayObject?(so how do I get the DisplayObject if that's the case?)
there's a need to select a mechanism, allowing user to hide/show columns in a DataGrid.One of suggested ways is adding a button (which looks like a column header, but with no column). When user clicks on it, the list of columns comes and user may select columns to hide/show. But is there any way to have such column in a grid (just a header with no column .. as example - you may see the grid in Mozilla Thunderbird)?
The other, less likely way, was the popup list, appearing when mouse hover the DataGrid. But this list would be used rarely. So, this flashing list would be just a headache for an end-user.
The ways with mouse-clicking .. I'm just afraid, that they would be left unnoticed and user would have a hard days while using a grids with a dozens columns.
Edit #1Maybe it would be better if I just provide a pic of this magical "header with no column", to escape confusion ..
Here's it .. there's a clickable column-header in a grid, but there's no column under it ..
Edit #2There's some area right above scrollbar in the dataGrid, it might be the right place for putting this functionality .. but it seems like I can't use it.
I am looking for a solution to complete within AS2 that allows a user to hover over a column header within a datagrid and a tooltip would pop-up.I'm completeing a sports statistics sheet within Flash and I am obviously putting numbers in each column, else I would use the full column header but its just a number so I don't want to increase the width of the columns just for that.If anyone knows of a way to make each individual column header able to pop up a tooltip plz post or recommend something. To give an example if it isnt obvious of what I'm trying to doLets say my Table looks like soGP | G | A | +/- | %

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.
need to load 10 records from database in advanced data grid. After i scroll the advanced data grid. it has to load 11 to 20 records etc.
