I have a datagrid with one datagridcolumn in it. Without a custom itemrenderer I can use a datatipfunction for showing a custom datatip but now I want to have a custom item render for colouring the rows differently.Therefore I extended a label and changed the data method but now my datatipfunction does not work anymore.

How do I differentiate between a data provider update and a itemrender being recycled when using a custom itemrenderer in a DataGroup?I have overridden the set data function of the custom item renderer, but I have found that on making a change to the ArrayCollection used as the DataProvider some of the item renderers are not assigned the same object they had before the update. This has made it almost impossible for me to distinguish between a data update and an itemrender being recycled. Also, the data never seems to get set to a value = null, so that seems to be out as well.
View 2 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?

View 1 RepliesI have posted two problems with a custom itemRenderer see this post. My primary Problem is, that it always selects a wrong line (one under the one I select). I now realized that this happens, when I save back the content of the itemRenderer to the dataProvider. If I code this part out, the dataGrid works as expected...

View 1 RepliesI'm currently building an application that is presenting tabular (fetched from a webservice) data and have squirted it into a datagrid - seemed the most obvious way to present it on screen. I've now come across a few limitations in the datagrid and wonder how I might move forward. The data is logically split into groups and I would like to be able to have subheadings in the grid whenever I move to a new group. I would like to be able to highlight individual cells based on their content relative to other values in the row - ie highlight the cell with the highest value in the row. Is this possible with the standard datagrid?

Firstly sorry for the really lengthy question. I am trying to implement an Org.Chart using spark DataGrid. The data for the Org.Chart does not change and hence I am hard coding the values. I had to implement this Org.Chart as I need to have floating Nodes and also the connecting lines should be drawn a bit different when compared to using an external component. Please find the following image of which Im trying to achieve: Here is the idea:

I'm having an issue with a custom ItemRenderer I've written for a DataGrid. With this ItemRenderer, it's possible that the contents could exceed the width and height of the DataGrid cell - and when this happens, scroll bars appear, letting me scroll the individual cell.What I would like, however, is that when the contents of the cell are too large, the entire DataGrid scrolls, rather than the individual cells.
Now, when I set the custom ItemRenderer's horizontal and vertical scroll bar policies to "off", I get the vertical scrolling on the DataGrid that I want (the individual cells stretch to accommodate the full height of the contents) but I don't get any horizontal scrolling. Instead, any content too wide for the cell is clipped. Incidentally, setting the DataGrid's horizontal scroll bar policy to "on" has no effect, the scroll bar gutter is drawn, but nothing scrolls Is there a way to force the DataGrid to scroll horizontally when my custom ItemRenderer's contents are too wide for the cell?

how to skin the datatip of a hslider component.
I have created a 3 skins with degrafa. One for the track, one for thumb and one for the datatip. I had no problem attaching the skins for the track and thumb of the hslider component. But how can i skin the datatip?
Is there any way to always show DataTip for SLider control in Flex 3.5?
View 2 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 !!

In Flex 4 (beta 2), I have a list control populated from an XMLListCollection. What I would like to do is when an item is selected in the list, use a custom item renderer on the selected item as well as the item that appears just prior to the selected item in the list.
I am using a spark list control, but I am open to alternate components if the solution makes sense.Here is the strucutre of the xml used to populate the XMLListCollection
