Flex :: Setting A Custom ItemRenderer In A ComboBox On Specific List Items After Combobox Creation?
Nov 8, 2010I'm trying to set a specific list item in a mx combobox to have a custom item renderer, the problem is that I cannot do this via mxml, it needs to be done via actionscript at a later stage, eg: combobox gets created, combobox gets populated, user does other tasks, combobox needs to set one or more items in the combobox to have icons (via item renderer)..
I can do this via the onChange event, but it only applies the icon when the combobox is opened and there is a slight delay so you can see the icon being added.

View 1 RepliesFlex :: EventListener To Watch For Number Of Items In DataGrid?
Oct 1, 2009Indeed the best for fast building of Web based Apps...
I'm trying to do something with eventListeners, but i still do a lot of messy code, so wanted help of those who already know flex.
I'm have a DataGrid, and its itens are added by another component, no problems with that.
I have buttons to Add, Remove and Edit the items inside the DataGrid. No problem with that too.
But i want those button to be enabled when the DataGrid as at least one item, and when it doesn't as any, all three buttons should be disabled.
EDIT: Forgot to say: I think eventListeners are the best way.

Sep 14, 2006I'm currently working on a project where I have a user defined list of urls which is saved in a local SO. When the movie is loaded the ComboBox is populated with the values from the SO (Stored as array inside SO).I want to give users the option to remove items from this list. So far I have managed to remove the selected item from the combo box, clear out the SO and loop the remaining ComboBox items, but, when I try and load these item into an array to parse back to the SO, the array is created and creates the correct amount of elements, but, each element is populated with only the data from the 0 index item of the ComboBox.My code so far: (This sits inside a button component and is invoked onClick)
_root.ComboBox.removeItemAt(_root.ComboBox.selecte dIndex);
_root.ComboBox.selectedIndex = 0;

Aug 15, 2010I'm creating a facebook application in flex. I'm actually working on the friends component that shows your friends who are using the application. now, each friend has a profile image.
I created the component using a s:List element.
In the Skin Class of the element i configured the requestedColumnCount to 3, which means it shows 3 friends. i added buttons to scroll left and right in the list.
Whenever I scroll to see a different friend, for a half of a second i see no image because the List component is loading the image in order to view it.
is there a way to make the list preload all the elements so i won't have this kind of problem ?

View 3 RepliesActionScript 2.0 :: Number Of Items Inside Array
Jun 30, 2011I have an Array where in position 0, there are two items "name1" and "name2", then in position 1, there is only 1 item "name3", and position 2 there is only 1 item "name4".
Now when I trace like this:
trace(exampleArray[0].length)
The result is 2;
But when I trace like this:
trace(exampleArray[1].length)
The result is 5;
I understand that on the second trace its counting the length of the item so its the number of letters that its returning. I'm just wondering how can I get it to return 1, which is the number of items in that position which is what I'm interested in.

var numOfWebItems = webItems.length;
but that doesn't work...
Here's the xml file:
