create a custom itemrenderer in Flex, whether there is some way to access the components that you place within the itemrenderer using actionscript? For instance, if I create a custom itemrenderer like this one:

<fx:Component>
<s:Group id="ThumbnailContainer" width="75" height="75">

Is there a way that I can access the "Group" container for each of the tiles that the program produces? So if I create a TileList, use the item renderer above, and have a dataprovider with 10 elements in it, is there a way that I can access or address the Group container for each of the 10 tiles that are created using actionscript?

I'm using a data grid with an item renderer that creates a toggle button. The idea is to have a list of items and only allow one to be selected and pre-select one at start.I've got the single button selection working, meaning that when I click on on toggle button, the others are deselected.My problem is to create a way of pre-selecting an element of the data grid or simulate a click on a row and selecting the corresponding toggle button.If I use the datagrid.selectedIndex the result is a selection but the toggle button doesn't get selected.Here is the code exampleIn this example I am using the array value "selected" to define selected button, not my favourite solution but the one that worked first.The array collection:
public static const ValuesList : ArrayCollection = new ArrayCollection(
[
{ID:0, Name:"One", selected:false},

View 5 RepliesI have prepared a simple test case for a PopUpButton opening a TileList with black and red entries and it mostly works, but has 2 annoyances. I've searched a lot, tried several variants (added [Bindable] members in my renderer; added color member to the bids array; created my public override set data() method; ...) and has been getting some answers too, but they are way too general.
1) Scrolling "tl2" right-left doesn't work well: the entries are displayed in a mix of red and black. I know the TileList reuses itemRenderer, but how do I fix the problem?
2) In debug-mode I get numerous warnings: warning: unable to bind to property 'label' on class 'Object' (class is not an IEventDispatcher)

I have created a custom item renderer for the tree, i have added some children in create children function, my problem is that sometimes i need to show these children and sometimes i don't, depending on clicking on a button which also i have added at create children, the problem is that i had to create the item even if i don't want it to be visible, and removed it by making visible false, and this costs a lot of memory, i have tried to create it at buttons click listener but when scrolling the child disappears, and it may appear again if i keep scrolling up and down.. i am trying to add the child just when i need it to be visible, is this possible or i have to create it on child creation method?
View 1 RepliesI have a Spark list with a customItemRenderer that is taking a good 3 seconds to initialize with just 50 items.

A few hours ago I've asked how to create a custom component (textInput and label component and created a Component Definition) and with your answers I can do that now.
Problem 2: I'd like to use that component in a datagrid column so that the user can type a value in the textInput which will in turn update the underlying dataprovider. I know I should use a cellrenderer like I've done with a checkbox column
I have a quick question about getting the value from control which I added in my data grid by Item render and how can I get that control object when I am clicking on the cell of that column.
View 1 RepliesI'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?
