Just wondering if anybody knows of an existing component that subclasses ComboBox but lets you specify an item in the list with a label like "all" or "none" that will set selectedItem to null? I've looked into writing one, and due to the internals of the component it looks like a lot of work, so I'm wondering if somebody's already done it?
View 3 RepliesI'm using a combo box control and the dataprovider is set as an XML. After the dataprovider is set, I want to edit the text of the first option and also I need to insert an item in the second position.
How can I do this? Using an ItemRenderer?
I'm currently having some trouble with referencing objects that turn out null on export. Basically I want the Document Class to run the code of another class that is the class of a MovieClip without having Error 1009 popping up everywhere in my output panel.

I've been trying to customize each cell in a ComboBox using a custom CellRenderer class, as instructed on this article. [URL]. However, my problem is I am trying to customize *only* two cells in the dropdown list. And the dropdown is populated by an XML feed so I cannot hardcode which ones to stylize beforehand. In other words, I want to make it look like an HTML dropdown. So, I have been looking for an alternative...maybe a property that I can use or another ComboBox component that can support option groups, like HTML dropdowns.
View 1 RepliesHow can you make a ComboBox where the user can select null?If you simply create a combobox with null in the dataprovider, the value appears but the user cannot select it:[code]Is there a way to make that null selectable?A workaround is to add an item into the dataProvider that is not null but 'represents' null; and then map between null and that object every time you access the combobox. But that's not really an elegant solution; you would always have to keep this mapping in mind in all code that accesses a 'nullable' combobox.It could be done in a subclass of course, but either I introduce new attributes (like nullableSelectedItem); but then you have to be careful to always use these attributes. Or I override ComboBoxes selectedItem; but I'm affraid that is going to break the base class: it might not like something changing its idea of what the current selected item is from within. And even this fragile hack works, on top of selectedItem and dataProvider this nullItem then also needs to be handled special in data and listData for renderers, in labelFunction, and then it's probably still being exposed in events the ComboBox sends.It might work, but it's quite a hack just to fix the problem that if the user clicks on the item it isn't activated (for the rest the ComboBox handles null fine).(Another alternative is to have a ui component delegate to a ComboBox, but that's even much more code just to avoid this small problem)

I'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.
How can I validate there's a selected item in a ComboBox before saving? If there's no selected item, how can I set focus on the ComboBox?

I want to persist the AdvancedDataGrid column order for the user if they move them around and close the window or log out. I have code (see below) that works when I place the code in a grid parent container - eg, a title window. I'd like to generalise the functionality by placing the code in an AdvancedDatagrid subclass rather than each grid container so that all my grids have access to a single location when saving/loading their choices. My approach is to store the datafield names and grid name in an array and save/read to/from the shared object. and update the column order based on that order. The invaldation fails when I use the code in the Advanced Datagrid subclass but works fine in the grid parent.
private function loadSettings(name:String = "custom"):void
{
var gridName:String = this.stripUIDNumbers(this.uid);
var temp:Array = new Array;

View 1 RepliesWith MXML components, I've seen a pattern used where you have an AS3 class, then the MXML subclasses it, to have a separation between view/code (anonymized from real code):
package com.john

public class MyComponent extends Canvas

At least I think the MXML component is subclassing the AS3 class?Anyway is it possible/advised to do this with my main MXML application file, so I can put manager instances and things in the AS3 MyApp class, which is subclassed by Main.MXML?

I want to extend DropDownList control to include an option for creating or editing the options. For example; for a list of projects in the dropdown list, there will be another option that says "Create new project..." or "Edit projects..." and this will be the last option in the list. When user selects this option, the selectedIndex or selectedItem will not change and corresponding action will be taken (for example a popup window shows up).This will be a convenient way for the end user. Now I want this to work independent of the context and the class must be reusable. User will only specify the optionText and optionFunction to work this out. The basic structure of the class looks like this:
public class OptiveDropDownList extends DropDownList
{
private var _enableOption:Boolean;

I have the following situation: have a screen with 4 charts, each being populated with 59 array collections. Each array collection has 2000+ data points. This construct needs to be filtered(by time), but the problem I'm encountering is the fact that it takes a long time for the filtering to finish (which is to expected given the amount of data points that need to filtered).
Filtering one chart at a time is not option, so I wanted to ask you what do you think would be the best approach? (should I use vector instead?). To generalize this question what would be the best way to filter large collections in flex/as3?
