I'm trying to update a List component pushing new items inside his DataProvider object.
I've tried with a:
MY_LIST.invalidateList();
MY_LIST.validateNow();
but the list doesn't change, anyone has some suggestions?
Is there a way so that every time the list is changed (data add, data deleted, etc.), the list will re-update or "refresh?"
View 2 RepliesI have a simple list and a background refresh protocol.When the list is scrolled down, the refresh scrolls it back to the top. I want to stop this.I have tried catching the COLLECTION_CHANGE event and validateNow(); // try to get the component to reset to the new datalist.ensureIndexIsVisible(previousIndex); // actually, I search for the previous data id in the IList, but that's not importantThis fails because the list resets itself after the change).I hate to use a Timer, ENTER_FRAME, or callLater(), but I cannot seem to figure out a way.The only other alternatives I can see is sub-classing the List so it can catch the dataProviderChanged event the DataGroup in the skin is throwing.
View 4 RepliesI am working on an older Flash project created in CS3 ActionScript 2.0 How can I make the pointer cursor change to the hand when hover over a list item?_root.slidePanel.myList'myList' is the list. I have traced out the contents of the List MC and it has a child MC called 'content_mc'. I assumed this was the object containing all of my list items but the only members of this MC I can see (when tracing them out) are 'setRGB' and 'searchKey'.

Theres any workaround for this? I have a listener for keyboard event that checks if keyCode is equal to 40 if it is then I use 'stage.focus = list', but I have to press 2 times key arrow down to start navigating through list items.
In Flex I can create an ItemRenderer to represent each item in the Lists DataProvider but how do I access the instance of the ItemRenderer via the DataProviders Object? Something like myList.getItemRenderer(dp.getItemAt(10));
View 2 RepliesBelow is a function set that's used to get info from an XML source(s) and populate a List Component (videoList). Works great. The second function loads data from a separate XML source and populates the SAME List Component. When the second function is called it loads the data in addition to the existing data into the List Component. I want it to REPLACE the data. How would I accomplish this?
public function getXMLdata(event:Event):void {
var campXML:XML = new XML(xmlLoader.data);
var vid:XML;
for each(vid in campXML.vid) {

I created an isntant of a list component on stage called "myList" and added 8 items to it.I need to align the labels in this list to the right or center.It's on the main time line and not in a seperate as file (if it matters...).I tried using setStyle but it failed (not the solution or I used it wrong).
View 3 RepliesI have a List of items which is based on the contents of the "category" that a user selects
When the user changes selection, I change the dataProvider of the list be be the contents of the current category.
Sometimes the list contains items, sometimes it does not
Is there a way of hiding the list when it has no items?
I know that I could do this when setting the dataProvider, but it seems like there should be an event or something else that I could be using.
I'm having troubles getting selectedItems from a List Component in Flash CS4. Each time I select multiple selections the object that selectedItems returns seems to be populated with the last selected item in each of its instances. What is strange from the example I provide below is that once you've made your selection and click the label you can update another list with the correct selected values. But the output values are still traced incorrectly.
Code:
import fl.data.DataProvider;
import fl.controls.List;
import fl.controls.Button;
var dp:DataProvider = new DataProvider();
dp.addItem({label:"Item 1"});

I need to be able to disable/grayout SOME items in a list component.
View 1 RepliesTo select all the items in myList I wrote:
myList.selectedItems = ['red','cyan','magenta'] ;
But what if I don't know about the items in the mx:list in advance? How can I select all the items in a list without specifying their names?
This question specifically deals with AS3 and list components and styling a selected item, if that's even possible. I've got an XML/Flash Video player that lists the videos with a thumbnail and description in a list component. I got the source files from an Adobe tutorial:[URL]...I'm able to style everything the way I want it. The problem comes when I try to attribute a specific text style to a selected item. I understand how the information is being taken from the XML and looped into the list component. What I don't get is how you reference a particular item in the list and whether or not you can attribute a different style to that item when the event listener fires.

im having some dificulties in the combobox of Flex 3, after defining the dataProvider and filling the combobox, how can i remove the items in the combobox later (without removing items in the dataprovider)? if i set the provider to "" or null, the items in the combobox are still there
View 1 RepliesI set my list to allow multiple selection. But when I load data in my list, I want to set a few items as selected. Normally you can set only one item selected by using list.selectedIndex. It only accepts int. How can I set multiple items as selected?

Is there an AS command that deselects (i.e. un-highlights) an object in a list component? Once a selection is made and a button is hit, I want the selection to go back to nothing!

View 2 RepliesI'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 ?

how to populate a list box component located within a seperate mc in my swf with an array... the array comes from a response from a webservice call. I am not currently on the computer with my source code available so lets just use the following....

movieclip1 = the MC within my fla containing the list box component
mylist = the actual list component

The 'recommendations' dataProvider is an ArrayCollection of String, which are generally sentences about as long as this one. By setting the variableRowHeight and wordWrap properties as shown, if a sentence is too long to fit on a single line, everything works fine- the row expands and the messages show on two lines, or occasionally three.
The space allocated for this panel within the entire canvas means if the total text size of 'recommendations' exceeds six lines, I need for the entire list scroll. This is also working just fine. The trouble is when using the mouse wheel to do the scrolling- Flex scrolls both the entire list and the single item where the mouse is hovering. Often this results in only the second half of a sentence being visible. Non-programmer friends I have asked to look at this noticed this, and tell me it as a problem. If a user does not notice the dual scrolling, and sees only a fragment of a sentence, it will be perceived as an error in the application.

I'm using a List which I need to be empty at the start. I'm adding items to it as needed by clicking a button. Since it's empty, I haven't added a dataProvider property
<s:List id="thelist" itemRenderer="listIR" />
To add an item, I'm adding it to the dataProvider directly
thelist.dataProvider.addItem()
but when I do that, it gives me this error
#1009: Cannot access a property or method of a null object reference.
Also I have a debugging Alert in the listIR itemRenderer itself and I see that when the list is created, I get that alert twice as if 2 itemRenderers were created, even though the list is supposed to be empty at the start.
How do I start with an empty dataProvider and add items smoothly to it?
while i using drag & drop from listbox1 to listbox2 ,how can i get all the items of listbox2 in flex
