I'm using a HorizontalList control with an XML file as a data provider. This is how the XML looks:
[Code]...
I tried using an array of objects as a dataprovider. The item renderer works and the horizontallist behaves as I expect it to. However, when I use an xml file, it's empty.... I don't know why it's not working.
i want to populate a horizontalList component from a xml file, the width value will be inside the xml file as well with all the data.actually i have this code:
<mx:Model id="epg" source="epg.xml" />
<mx:Component id="customRend">
<mx:Label text="{data.description}" width="{data.width}"/>

I am having some issues when trying to skin the scrollbar on a horizontalList with Degrafa. The scrollbar doesn't show up at all. I checked to see if the scrollbar is supposed to show up without the skinning, and it does.Here is some code:This is where I define the HorizontalList where I want a skinned scrollbar.[code]I am populating the HorizontalList with more items than are viewable, and like I said before the scrollbar shows up when I remove the skinning.
View 1 RepliesI'd like to remove the rollovercolor of a horizontallist (my component has a background image)I've tried using a css style sheet by setting the "roll-over-color" property to "transparent" But I get a black background >_<
View 1 RepliesI have a HorizontalList that is resized at runtime. The problem is that the items are not adjusting their height to the height of the HorizontalList. I use an item renderer (vBox) which has its height set to 100%. But the items always stay at their initial size.

As you see, I try to make my HorizontalList focused when application is loaded. And I actually receive Received focus message in console. But I expected that I would be able to navigate over list elements with arrow keys after setting focus. But that's not the case. They work only after clicking component with mouse. How to make list have focus and respond to arrow keys?
I'm trying to remove an eventlistener on (in this specific case) a HorizontalList. The list is initialized with the property itemRollOver="playPreview(event)" I'd like to remove this eventListener by switching state and stating something like: <mx:SetEventHandler target="{horList}" name="itemRollOver" handlerFunction="null" />
This doesn't seem to work. The event is still handled and playPreview(event:ListEvent) is still called. How to properly do this? (I know I can do it in Actionscript, but I specifically want to do it by means of state switching)
I know how to display data in a List control using dataProvider but what about control that don't have dataProvider e.g. TextInput, Label contorl?[code]Try to use {dp.ID} and {dp.getItemAt(0).ID} on TextInput but nothing being display?How to make TextInput id=" first Name" able to display the SQL data?

The flex DataGrid colums are arranged alphabetically by default. I need to order the DataGrid colums as per the order in its dataProvider. The dataprovider is the result of the HTTPService . And the number of columns is not known to us . The number of columns depends on the HTTPService result.

How do I set the dataprovider in actionscript? I have:

adg1.dataProvider = pagedResult.lastResult;
}
i m new in flex and was trying example but getting nothing

i think i m doing something wrong in dataprovider tag reason is when i use dataProvider = "{d}"

View 4 RepliesI am creating the standard "Click to add row" control but I really don't want to dirty the dataProvider with a "placeholder" since it is bound to the model and could end up in the database. Is there a way to add a row that isn't represented in the dataProvider? I started down the road of adding an item directly to listItems but then that needed an item in rowInfo and then that need a reference in rowMap.

I'm trying to set a combobox's dataprovider.I have 2 comboboxes: cb_div and cb_stores.For cb_div, I get to set the data provider correctly with an XML file.Cb_stores' dataprovider is to be set depending on the selected item of cb_div.First, here are my XML files.Data provider for cb_div:

I have a project that was compiled with the Flex 3.2 SDK. One of my components is a combobox, which is bound to a property (called products) in the Cairngorm model. If I insert a new value into model.products, then the combobox immediately shows the new value. Works perfectly.
I then moved to the 3.5 SDK, and running the identical operation causes a problem. Even though the model has been updated (I have verified that this is definately the case), the combobox does not show the new value correctly - it seems to be aware that there is a new item because there is a new row in the combo, but the new row is blank and unselectable. The existing items in the combo are there and selectable (as they should be). If I re-initialising the form (i.e. close and re-open the TitleWindow on which the combo is located), then all the correct values (including the new one) are shown in the combo.
I have swapped back and forth a few times between 3.2 and 3.5 to verify that this is indeed the root cause.
What I would like to do is simply add to a dataProvider, but when I do, I get an error. Here's the code I'm trying to run...
dg.dataProvider.addItem(obj.ResultSet.Result[i]);
It's inside a for loop, using i as the integer. It works great doing...dg.dataProvider = obj.ResultSet.Result But that won't work for me, because I need to add to the dataprovider more than once. I'm getting results in batches of 10, and I need to add each batch to the dataProvider when it's received. I also tried to to do...
var dgDP:dataProvider = new dataProvider(); But for some reason Flex doesn't recognize it...
I'm implementing some kind of combobox control (by extending spark.components.supportClasses.DropDownListBase)
Now, inside this control; I need to know:
If the dataprovider is changed/assigned. (which I can do... the first approach below works); if any item in the dataprovider collection has changed.
I tried 2 methods that did not do the trick...
1ST APPROACH:
2ND APPROACH:
UPDATE: Edited above.. The first approach lets me know if the dataprovider is changed but not if any item is updated in the dataprovider collection. The second approach does not work at all..
How can I set a function to be called when the length of a DataProvider changes?

I've got a model class with a bunch of Number variables that change frequently. They all dispatch their custom events, thus are bindable. In my UI, a couple of those class instances are bundled into an ArrayList that serves as the dataprovider for a Spark DataGrid. The class variables change perfectly fine, so problem there.
What I'd like to do now is to change the color formatting of those numbers (the corresponding labels in the gridcoloums to be exact) depending on the data that comes in, so to say change in green when the new value is bigger, change to red when the new value is smaller than the old one.

I have a list object and I'm adding items to it with addItem through the dataProvider.Before adding an item to the list I want to make sure it's not a duplicate. I've tried using indexOf on the dataProvider and it returns null. I've tried casting it to an array and it works, but always returns -1 even if the element exists in the dataProvider.The only method I've been able to use seems a little hacky and I'd like to know if there is a better way to find an element in a dataProvider.

In my Combo box i have to shows team names condition based . So i will try like
dataProvider="{usersXML.users.user.(id=10).name}" but shows some errors . but if i tried
dataProvider="{usersXML.users.user.name}" display all name . It's working .
How can i condition based to display the list . In combobox . Plz refer me . is it possiable to check array of id on the dataProvider ?
i 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 ?
I need to use DataProvider class and i cannot find the package that contains it. In all examples I saw they use fl.data, but I'm using flex builder sdk 3.4 beta and it doesn't have such a package.
