My 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 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 list with custom item renderers. What I would like is when one of the list items is selected to position another control OUTSIDE the list to the same vertical position as the selected item.

View 5 RepliesI 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'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"

How does one go about calling a skinClass on a DropDownList component without compromising the typicalItem functionality?

dataProvider="{colCompetente}" editable="false">
<mx:columns>

What I want to do is, when I select an item in the datagrid, the selected item of the dropdown should be the correct one (the one which has the field idCompSuperioara equal to the third element in the selected datagrid row).
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,
<s:states>
<s:State name="normal" />
<s:State name="hovered" />[code]........
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.

What I need to do is make sure that something is always selected in the list (unless it is empty)

View 1 RepliesI am using a combobox for the us states, link. The label is set to the full name of the state, while the value attribute holds the abbreviation. What I want to do is to get the selected item's value. So I tried combo.selectedItem.value and combo.selectedItem.@value, but neither of them worked.
View 2 RepliesI have a XML based Tree Control. The XML Structure is recursive, so the children's can have the same Element as the parent. I now want to let the user add and remove the elements. Do do so I need to get the parent element of the selected Item. Following code I already collected together:
var selected:XML = treeControl.selectedItem;
parent.insertChildAfter(selected:XML, newElement);
I just don't know how to get to the selected parents node as there is no such method like treeControl.selectedItem.parent.
I have a TileList with thumbnail images. Under each thumbnail images I display the name of the image. I want to build rename functionality. So under the TileList is a "Rename selected image" button.
When this button is clicked, I would like to change the state of the itemRenderer component. The label underneath the image will change into a TextInput so that the user can type a new name. This is much like the Windows rename file functionality.
How can I access the itemRenderer of the selected image? How can I make it happen that it listens to the click event of the Rename button?[code]...
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

View 1 RepliesI'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.
