I change an item in Spark List. The item then moves to a different index in the list since I keep the List's dataProvider sorted. However, the selectedIndex stays where the item used to be. I want the List's selectedIndex to still be on the item that changed.

View 8 RepliesI've just recently started out using Flash Builder and have a question surrounding states. In fact I'm not entirely sure it is related to states but read on and I hope it will become clearer. I currently have a custom component that contains 3 comboboxes. This resides in a TabNavigator component. The TabNavigator consits of 5 pages (Tabs). The custom container holding the comboboxes should display the same selected data across all Tabs. ie. If I am in Tab1 and select an item from one of the comboboxes then click on Tab2 I need to mirror the combobox's selection in Tab2.
View 1 RepliesMy stakeholder has a request to remove the currently selected item from the DropDownList control(s) in the application. For example a drop down with [item1, item2, item3, item4] if item2 is selected then the only items in the drop down will be [item1, item3, item4]
Using Flash Builder 4 with Flex 4.0 sdk
I have a spark list, which is based on a dataProvider. As the application runs, the data in the dataprovider can change, and also the dataProvider can be swapped for a different one
What I need to do is make sure that something is always selected in the list (unless it is empty)

I want the selectedIndex to remain the same. So, if I delete item 2, the next in the list should be selected. The problem is that if I delete item 2, item 3 will be selected and I have no idea why.
I'm having a problem with getting the value of an item that the user selects in my mobile Flex application. When I select an item from the list I place that item into an ArrayCollection. But when I check the value (trace()), the value is [object Object] and I can't seem to access the actual value of the object. Here is what I am doing:
private var selectedPlayers:ArrayCollection = new ArrayCollection();
private var numOfPlayers:int;
...
//check if item is not already in selected players list

I have two spark lists and want to drag items from one list to the other. When im dragging an item and over the other list item, i want the target item to change the background coloer.Basically instead of showing the black line indicating that I will drop between elements, I want to see the target item highlight.
View 1 RepliesHow do I wordwrap in a spark list w/ an itemrenderer? This posting at[URL] works 100% but when I try to set a separate item renderer, I can't get the word wrapping...instead, I get an ugly horizontal scroll bar. HEre is my mxml:

I can still keep the color of selected item even if it's rolled over? In my code, I have specified both the selectionColor and rollOverColor as below:
videoList.selectionColor = "0xCC0033"; //red
videoList.rollOverColor = "0xE9F3FF" //light-blue
It works well except when the selected item is rolled over. When the selected item is rolled over, it changes the color from red to light-blue. I want the selected item to stay red even when it's rolled over, but haven't found a way to achieve this.
I have a Flex Spark List (well it's a Tree to be precise but it renders as a list) and as I'm scrolling through it I want to provide information about the item that is currently at the top of the list in context to the viewport. So this could be the 100th item in the list depending on how far you've scrolled down.
View 1 RepliesI'm trying to make a simple flash application providing interface for taking tests as a high school assignment. One of the requirements is to use an XML file as data source.Now, having a List component bound to the XML file with questions consisting of data such as question body, question type (ie. single choice, multiple choice, open, image etc.) and possible answers (where applicable), I was wondering if I could add some additional data (and what is the best possible way to do so) to each question upon its transfer to the List component.
I am trying to achieve two main goals with this: firstly, to mark the questions to which an answer has already been given, like with such code in ItemRenderer class:
<s:Label color="{data.color}" text="{data.label}"/>
Where data.color would be set whenever the user gives an answer to a question.
Secondly, while at it, I thought of such possibility as a great way to store answers given to particular questions. In this case, the Class of the answer object would have been Object, since there has to be many type of questions (where the answer could also be a Bitmap for example).
I have a regular spark list which is sorted correctly when no item renderer is used. However, when the following item renderer is used, the list shuffles and displays items from previous instances of the list.[code]
View 2 RepliesBecause of screen size, I must ensure we're only displaying necessary data to the user.I have a drop down box that contains only 5 items and I would like that when an item is selected, it doesn't appear in the drop down box (since technically it's showing twice, once at the top as the selected item and once in the list). how I would achieve this? I tried using a custom CellRender and overriding the "set selected" function to call this.visible = false if selected is true, but that simply hides the item but does not remove it from the layout of the drop down list.
View 1 RepliesIn Flex 4 (beta 2), I have a list control populated from an XMLListCollection. What I would like to do is when an item is selected in the list, use a custom item renderer on the selected item as well as the item that appears just prior to the selected item in the list.
I am using a spark list control, but I am open to alternate components if the solution makes sense.Here is the strucutre of the xml used to populate the XMLListCollection

I am trying to get the index of an item in a List object on a mouse roll over event (please keep in mind this is not the selectedIndex I need). Heres the code I am currently using:
list.addEventListener(ListEvent.ITEM_ROLL_OVER, onItemRollOver);
function onItemRollOver(e:Event):void {
var itemInfo:Number = 0;
/*This is where I need the Index Number of Item being Rolled over instead of Selected Item*/
itemInfo = list.selectedIndex;
txt_Display.text = 'Item Index #: ' + itemInfo;
play();
}
In a flex application how to display default selecteditem from the dataprovider of the combobox.
I'm using {staticdataholder.currencylist}.
For example: I have to show INDIA so it should be selected as default from the list.
I have a List component using multiple item renderers determined by the itemRendererFunction. When I set the data the first time, it works as expected. Then, when I set the data a second time with new data, it doesn't call the itemRendererFunction and tries to reuse the current renderers even though they don't match the data.Once I scroll, the function is called and the correct renderers are used. I tried calling invalidateDisplayList and such prior to setting the data, but that didn't fix the problem.
View 3 RepliesI have an issue with Spark Lists whereby I am trying to ensure that an item is always selected and ensure that the GUI displays this to the user.
The application (full code below) creates a List, a Label and a Button. The Label states what is selected in the List. The button removes the selected item. Changing the selection, updates the text in the Label. Important: The List has "requireSelection" set to true to ensure that an item is always selected.
If I select the first item in the List, the selection is correctly reflected in the label. Clicking "Remove" removes the item and the next item is selected. This is all working correctly.[code]...
In a spark list I could use the change event to find out which item has been selected or deselected. The dispatched IndexChangeEvent object has the properties newIndex and oldIndex holding this information.
But with multiple selection allowed this doesn't work anymore because newIndex and oldIndex could refer to indices of still selected elements.
A solution would be to copy the selectedIndices vector to another variable and compare this variable with selectedIndices after a change in selection, but this seems to be somewhat complex.
Does anyone know if there is an easy way two get the index/item a user is deselecting while other elements are still selected?
I have a spark List defined as:
<s:List id="symbolList" dataProvider="{symbolListCollection}" change="symbolNameChangeHandler(event)"></s:List>
With the change handler defined like this:
protected function symbolNameChangeHandler(event:IndexChangeEvent):void {
symbolList.validateProperties();
changeSymbolView(symbolList.selectedItem);
}
and symbolListCollection as an ArrayList filled with Strings.
At first, the change event works fine, and I get what I expect.
However, if I Ctrl-click on the selected item, to de-select it, i am unable to ever select an item again.
When I click on something to try to select it, the change event DOES fire, however, the ItemChangeEvent has both oldIndex and newIndex set to -1
I am having problems making a movie clip goto a different frame when an item on a list box is selected. Here is my code

}else
mc.gotoAndStop(1);

I have prepared a simplified test case for my question. It will run instantly in your Flash Builder if you put the 2 files below into a project.I'm trying to display a List of strings and a confirmation checkbox in a popup:In the real application I dispatch a custom event with the string selected in the list, but in the test code below I just call trace(str);My problem: if I use click event, then the window closes, even if I click at a scrollbar (the !str check below doesn'twhen an item had been selected in previous use). And if I use change event, then the window doesn't close, when I click on the same item as the last time.riting a custom item renderer and having a click event handler for each item seems to be overkill for this case, because I have strings in the list.Test.mxml: (please click myBtn few times - to see my problems with click and change)

I have used states in my application.The thing is I have made the first item in my list to be selected. so I gave like this,
if(itemIndex == 0)
this.currentState="selected";
this works fine.The problem is when other item is selected the first item does not change its state,it remains in the selected state until its clicked.My code looks like this,
<s:BorderContainer id="outerCont" width="275" height="100" borderVisible="false"
backgroundColor.normal="#3D3C3C" backgroundAlpha.selected="0.1"
backgroundColor.selected="{data.color}">
My states are like this,

Loading thumbnails using this method works perfectly. The issue happens when you scroll the List.
