Feb 3, 2011Is there a way so that every time the list is changed (data add, data deleted, etc.), the list will re-update or "refresh?"

Flex :: Keep A List From Scrolling On DataProvider Refresh/update/change?
Jun 30, 2011I 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.

Flex :: Repeater With Dataprovider Flickers A Bit When There Is An Update
Dec 16, 2009i have the following code:
<mx:Repeater id="user" dataProvider="{data}">
<mx:VBox styleName="repeaterVBox">
<mx:Text text="{user.currentItem.a}. {user.currentItem.b}"
[Code]....
the dataProvider 'data' updated itself every 3 seconds, so every 3 seconds that is a flicker of some sort, i see for a really short time an empty area and then it gets redrawn again. is there a way to make the update somewhat faster ?
Flex :: Flash - Programmatically Select An Item In A List After DataProvider Is Updated?
Jan 2, 2011I have a Spark List container whose dataProvider is bound to a result set coming back from a RemoteObject call. Pretty standard stuff.
<s:List id="list" dataProvider="{model.stuff}" width="100%" height="100%"
selectedIndex="@{selectedSlider.value}"
itemRenderer="{stuffRenderer}">
</s:List>
The selectedIndex is associated with an HSlider, but that is not the problem. My issue is that I would like to automatically select a certain "preferred" element from the list (only initially...to guide the user).
I tried to do that in a creationComplete event but my data hadn't shown up yet...setting selectedIndex didn't work..

Flex :: Starting With An Empty DataProvider For A <List>
May 25, 2010I'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?
Flex :: Get The ItemRenderer Of A Spark List From Its DataProvider Object?

View 2 RepliesFlex :: Resizing List Components Upon DataProvider Change
Jul 10, 2011I have a component that contains a list that implements a custom renderer. I use this component as a tooltip, keeping one in memory and just altering the databindings as necessary.
Something like this where TTComponent is a class that extends Canvas:
<s:TTComponent>
<s:BorderContainer>
<s:List id='lstItems' dataProvider="{data.Items}" width="50%" borderVisible="false" contentBackgroundColor="#222222">
[Code]....
Now, what happens is when data containing many items is set to tt.data, the list resizes itself larger and displays fine. However, after this, if data containing few items is set to tt.data, the component momentarily displays larger than it needs to be, then resizes itself smaller.
What I'd like to do is have the component resize itself before it displays, so I don't see the resize on screen.

Flex :: List DataProvider Implicit Coercion Error
Feb 21, 2012I have this error. I am very very new to the Flex world. I have this function which returns an ArrayList.
public function createDataProvider():ArrayList {

return new ArrayList(imgArray);
}
Later, I use it here:
<s:List id="pubmapList" dragEnabled="false" dropEnabled="false" dragMoveEnabled="false" dataProvider="{createDataProvider}">
Here, I got an error saying: implicit coercion of a value of type to an unrelated type mx.collections.ilist. I thought the IList implementation includes ArrayList.
Flex :: Change Dataprovider In Spark List That Has Itemrenderers?
Mar 13, 2012In flex 4.5, I have an application that has a BorderContainer that loads a spark list (mxml style - _myList and the borderContainer is stored in a library outside of the parent application) that loads an arrayCollection with an itemRenderer (I should note said itemRenderer is not an inline renderer - on selection of an item in the list, the itemRenderer expands, loads a particular control within the item renderer based on data passed from the selected item in the list) and allows the user to perform a search. This works all well and good on startup/load, until I try to change the dataProvider for the list (my app allows users to switch data sources which then creates a new dataProvider with new variables). I have tried:

Flex :: Combining A Multiple Strings And Arrays To One DataProvider For Spark List
Dec 21, 2010what I need to do is combine 5 arrays with 5 individual strings (which have come from a JSON webservice) into one single list item in FlashBuilder Burrito. [code]I've pulled these out successfully and each one traces in the debugger, although as I need them all in the same list I'm struggling to establish them as a dataprovider together.If I push the strings and arrays together it is impossible to read properly, as the main Titles are at a different level to any descriptors for the products which are in the arrays.

Feb 21, 2011How does Adobe Flash launch auto-update message as soon as I logon on Windows? I thought Flash is only a browser plugin. I tried look for the program it runs, but can't find it in all the usual places: Start Up group in Start Menu, HKLM Run, HKCU Run, Services.
I know it is possible to disable this via Flash preferences. However, I need to remove it mechanically once and for all, because it seems like a security risk to me (as hackers would be able to exploit a Flash installation even if the browser has not been launched).
