I am trying to create a dropdown that can display both past state and possible state for a customer.But I want to make add a separator between past and possible state.Actually to do that I add an item like "-----" on the dataprovider.But the look and feel is not good and this item may be selected.My ideal approach is something like that:
View 2 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]

I have a s:List where I've defined my own itemRenderer, and would like to insert a horizontal line separating items, similar to the way the mx:LinkBar works. I don't want to have a line at the top or bottom of the list, so I can't just include an upper or lower border in the itemRenderer. I was hoping the itemRenderer could be made aware of its index in the list, but I don't see how.
View 2 RepliesI must display very small values (capacitor) in a Flex-AdvancedDataGrid I use spark.formatters.NumberFormatter. If I use 3, 6 or 9 for fractionalDigits, everything is fine.
But if I use 12, because I need 12 digits after decimal separator, then the value is cut after 9 digits!
Is there a way to get more then 9 digits after separator.
Or is there a way to use a formatting like "4.7 E-12" (Must be E-9, E-12, E-15 and so on)
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)

I have a spark dropdownlist and I have applied custom skin on it to display images in it instead of labels.
<s:DropDownList id="id_cbLineType"
skinClass="assets.skins.SkinDropDownImageList"
itemRenderer="spark.skins.spark.DefaultComplexItemRenderer"
[code].....
How does one go about calling a skinClass on a DropDownList component without compromising the typicalItem functionality?

I am using FlashBuilder 4.5 for PHP. I have a simple MySQL table with the fields {tID, tName}.I am able to populate a DropDownList in a Flex form as below. The DropDownList shows the name of the people without problem:
<s:Form defaultButton="{button}">
<s:FormItem label="myList: ">
<s:DropDownList id="dropDownList" creationComplete="dropDownList_creationCompleteHandler(event)" >
<s:AsyncListView list="{getPeopleResult.lastResult}"/>
[code]....
The above does not work.
I have a data grid with a custom item editor that displays a DropDownList component. When I click the scroll bar in the component, it is firing a focus out event on the list, which is causing itemEditEnd to fire. Why the list is not keeping focus, or how to make it keep focus. I'm using Flex 4.

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've been playing with s:ComboBox and generally like them a lot. One detail is driving me nuts though - most likely due to my lack of knowledge in the subject - is that if I try to add a new item to my dataprovider in a changeHandler (registered to the change event) the text for the ComboBox textInput disappears - although the item addition works perfectly. Interestingly enough the same operation works fine if it gets called by clicking on a button, i.e. post the change event has been processed, and the text does not disappear.[code]if you take out the change handler you will see that adding a new item and then clicking on the button keeps the new element in the textInput while adding the item to the data provider, which does not happen if you just enter a new item and press enter.
View 1 RepliesI 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).
Is there a way to change the space between a spark form item and its content (textinput, combobox)? I already set to 0 the "gap" property of the form, but still there is a lot of vertical space left between the form inputs.

View 8 RepliesI 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 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 1 RepliesI have a spark datagrid on a mobile application, I set the

How can I add the touch dalay before select the index, so if I scroll the grid the selection won't change, and it change only if I press the item without scrolling?

I'm trying to prevent a default chart item roll over highlight in a Spark column chart.If you look at any of the chart examples on this page , when you roll over any of the chart series items, they turn a darkened shade of their original colour. This is what I want to prevent.
So far I have had no luck with using the itemRollOverColor property, as this only allows you to set it to one specific colour for the whole chart (my app has several different coloured series on the chart at once). Also, trying to leverage the itemRollOver event (with preventDefault() etc) hasn't worked either.
I have a project that needs to store user input on the server, then be able to reload it later.I am interested in opinions as to which separator would be best to use, ie comma, semicolon, tilde, etc. Of course whichever character it is, it will be restricted from usage by the user, so it must be uncommon.I'm leaning towards using the tilde, since I already use input textfield restrictions to prevent backticks for server security (same key on the keyboard). Seems to me as if the tilde is a very rarely used character, and so should be fine to exclude it from user inputs as well.
