Flex :: Access ItemRenderer Of A Selected Item?
Feb 3, 2010
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 have this datagrid:
<mx:DataGrid id="dgCompetenteN" includeIn="Test" left="10" right="472" top="69" bottom="149"
dataProvider="{colCompetente}" editable="false">
<mx:columns>
[Code]....
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]........

have an advanced datagrid with a simple custom mxadvanceddatagriditemrenderer. I want the renderer to only display an image when the row is hovered or selected. Right now I am doing that by using the excludeFrom="normal" tag on my image.
It works fine (minus the selected state, it disappears when selected) when I have the states hovered and normal defined. When I try to define a selected state, upon row click I get the following error:
RangeError: Index 0 is out of range.

I have a List with textInput as itemrenderer. Initially the list is loaded with data from a data provider. However since the items are rendered in textInputs, I have the ability to change the value of a particular item.
But when trying to access the value of the changed item using the function below, I still get the old value in my trace:
private function addItem(event:Event):void {
trace(myDataProvider.getItemAt(myList.selectedIndex).label);
}
what I need to do for the new value to be available. My itemrenderer is shown below:
<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"

Anyone know how to change a single instance of an item renderer for a Flex tree item at runtime? To reiterate, I'm not trying to change the entire tree's item renderer like this:tree.itemRenderer = new ClassFactory(ItemRenderer2);I'm trying to change the item renderer of a single tree item like this (the following code does not work):tree.selectedItem.itemRenderer = new ClassFactory(ItemRenderer2);To put it more simply, does anyone know how to reference an instance of an item renderer and set it to a new item renderer class? I've tried using the Tree's itemToItemRenderer() method with no success.

I 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.

I 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'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

In 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'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.

I have a ComboBox with a label function like this one:
private function fieldLabelFunction(item:Object):String {
return resourceManager.getString('dashboard',"SS." + item);
}
When I change locales, the labels display correctly in the ComboBox's dropdown list, or if I change a selection. However, the currently selected item's label doesn't refresh at first. Is there a way to force the labelFunction to get called again?
