Flex - Use A Different ItemRenderer For Different List Items?

Aug 3, 2010

I have a Flex list and a custom ItemRenderer. I'd like to be able to have some items in the list use a different ItemRenderer (say, depending on the class of the item). Is this possible?

E.g.: <s:List dataProvider="{_systems}" itemRenderer="myItemRenderer"/>

Most items in _systems use myItemRenderer. But if element 3 of _systems is "specialSystem" the renderer would be "specialItemRenderer".

Flex :: Setting A Custom ItemRenderer In A ComboBox On Specific List Items After Combobox Creation?

Nov 8, 2010

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.

Flex :: Set SelectedItem In DropDownList?

Sep 10, 2011

I am making some simple project and I have problem with selectedItem. I have sth like this

<s:State name="Form" enterState="makesService.send()"/>

so when I enter this state I take makes from database and populate them to dropdownlist.

but I have also button and on click event I'm changing state to this Form and I want to select specific make from the dropdownlist but I can't. I'm not sure whether I'm doing sth wrong or the problem is that I'm selecting item just before the dropdownlist became populated.

Flex :: Force The List To Load All The Items, Not Only The Visible Items?

Aug 15, 2010

I'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 ?

Flex :: Specify Individual Fonts In Flex DropDownList?

Feb 8, 2011

I have just implemented a dropdownlist of checkboxes taken from this ComboCheck example but made it extend DropDownList instead of ComboBox to provide better functionality that I required. I am attempting to create a DropDownList where some items are bold and non-checkboxes (or can be checkboxes) and others are not.

I have not been able to find anything online about doing this yet and have been trying to figure it out. I am currently using an ArrayCollection as a dataProvider but I think this could possibly be my issue and I should be trying to setup the labels in flex not AS3.[code]...

Flex :: How To Change Open DropDownList Height

Feb 18, 2010

Using FB4, I want to change the height of an open spark DropDownList. By default, it shows up to 6 items before scrolling. My dropdownlist contains 7 items, so I want to change the height of the open dropdown list to fit all 7 items without scrolling. As a workaround, I've changed the font size of the items so that they are smaller and all 7 fit, but the smaller font doesn't look good. Is there a way to change this height?

Flex :: DropdownList Does Not Show The Correct Values

I have a Flex Spark dropdownList in which I need to show the Provider FirstName,LastName:

Flex :: DropDownList Doesn't Work In New Window

Oct 29, 2010

In this code I'm creating a new window when I click the button. In the new window are TextInput and DropDownList components. When the new window opens, clicking the DropDownList does nothing - you have to click it a second time round to get it to open. However, click into the TextInput field first and then try opening the DropDownList works no problem.

Below is the code, or download the FXP file here.

Flex :: Spark DropDownList As ItemEditor Within AdvancedDataGrid?

Mar 11, 2011

I'm trying to use the Spark DropDownList as itemEditor in an AdvancedDataGrid. Howerver, I've stumbled onto two issues:Clicking on a item in the DropDownList changes the selected row in the ADG. You can see this behavior by compiling the code from below and executing the following steps.The value changes from "A" to "C" and Row 3 is the selected row in the ADG. It looks like the mouse click in the DropDownList is also handled by the ADG itself which changes the selected row accordingly. I couldn't figure out a way to prevent this. The expected behavior would be that row 1 is still selected after the DropDownList has been closed.Clicking on the scrollbar of the DropDownList closes the DropDownList. (I just found the solution to this problem in the relatated questions while writing this: Scrollbars in dropdownlist inside DataGrid itemEditor not working)

Flex :: DropDownList Doesn't Always Open On Click?

May 12, 2011

I have an AIR application with 2-3 DropDownLists and a bunch of other controls. The DropDownLists are bound to dataproviders (ArrayCollections) in a central Model singleton. On launch, they all work fine.

However, when I click a button to add new objects to an object in another ArrayCollection in the same Model, the DropDownLists get weird. They still register clicks, and all other controls still work as before, but the dropdowns won't open. Clicking/waiting enough usually opens the dropdown, but if I don't make another selection it still won't open after closing. Making a different selection makes that DropDownList work again, but the others might still refuse to open.

If I open the dropdowns using Ctrl + Down arrow, they work all the time, so it's only the click that doesn't trigger the open correctly. I can work around the problem by calling openDropDown() on the dropdown when clicked, but that doesn't feel right.

I'm using the 4.1 SDK, and the dropdowns are s:DropDownLists. I tried using mx:ComboBoxes instead, but got the same behavior. Edit: Weirdly enough, using s:ComboBoxes they work as they should, but I really don't want to use them since they seemingly can't be made non-editable.

Flex :: Extending DropDownList To Include An Extra Option?

Mar 27, 2011

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;
