flex datagrid itemrenderer
I am experiencing some rather quirky behaviour with datagrid itemRenderers. First, I create an ArrayCollection as follows:[Bindable] private var myBooleans:ArrayCollection = new ArrayCollection([false,true]);And afterwards I bind it to a datagrid:<mx:DataGrid dataProvider=”{myBooleans}” width=”100%” height=”100%”><mx:columns><mx:DataGridColumn xmlns:mx=”library://ns.adobe.com/flex/mx”headerText=”Value”editorDataField=”selected”rendererIsEditor=”true”itemRenderer=”mx.controls.Chec

list flex4 itemrenderer
I am trying to use two different item renderers via view states (detail, or open). The itemRenders display different data and different sizes. When a list item in the Opened state is clicked, the state is changed to detail and a new itemRenderer is used. However, the updated list clips content past 25 items. I have tried invalidateDisplayList() but doesn’t seem to work. Thanks for any the help.<s:List id=”list”currentStateChange=”{list.invalidateDisplayList(); list.measuredHeight = 20000}”dat

flex itemrenderer
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 i

flex image runtime itemrenderer
in datagrid I have an ItemRenderer (which extends UIComponent) which loads images based on a data value, eg:_img.source = “assets/images/flags/” + value[dglistData.dataField] + “.gif”; When I run my application the images (flags) are appearing in the ItemRenderer. When I build and deploy the application into BlazeDS as an SWF file – the images do not appear. Instead there is the standard “missing icon” link that appears in Internet explorer.As far as I can tell, my ANT build script includes the

When I run my Flex 2 app I get the following runtime error:TypeError: Error #1009: No se puede acceder a una propiedad o a unmétodo de una referencia a un objeto nulo.In other words, the Flex SDK is telling me that the “lb” variable inside my ItemRenderer is null (I checked with debugger and yes, it is really null) What am I doing wrong?The line which triggers the error is this one: lb.text=value.spe_name;My tilelist:<mx:TileList variableRowHeight=”true” liveScrolling=”false” width=”100%” tex

flex list spark itemrenderer dataprovider
In flex 4.5, I have an application that has a BorderContainer that loads a spark list (mxml style – _myList and the borderContainer is stored in a library outside of the parent application) that loads an arrayCollection with an itemRenderer (I should note said itemRenderer is not an inline renderer – on selection of an item in the list, the itemRenderer expands, loads a particular control within the item renderer based on data passed from the selected item in the list) and allows the user to per

I am building an app for a website that will filter through the shops carrying some products/brands and show the results in a List component. I got all the way up to loading the data, putting brands/countries/cities in comboboxes so a user can filter in which country and city he wants to look and for which brand. No problem till now. My problem is that while the dataprovider works as it should when hardcoding some values to the labels that i use for the item renderer of each entry, i cannot get

flex data-binding datagrid itemrenderer datagridcolumn
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

flex tree scrolling itemrenderer
I have created a custom multiline item renderer for mx:Tree component. Important to mention that my item renderer has two UITextFields in it. Sometimes (depends of the input data) only one of UITextFields must be shown, so when second UITextField is not needed I hide it and recalculate the height of my item renderer. According to my tests height is calculated properly.The problem occures when I do scroll of my tree. The error text is:TypeError: Error #1010: A term is undefined and has no propert

database flex itemrenderer datefield datafield
I’m really stuck on this one. I have setup an Itemrenderer in a Datagrid which manages a DateField. Users can enter a date and other values directly in the datagrid. When they click ‘submit’, I want to populate a row in a database and I have setup a service for this. A row is created in the db with all values from the datagrid as expected however the date is not populated despite users having entered a value. Below is a code snippet:Datagrid<s:GridColumn dataField=”datf” headerText=”Period Fr

I have a database including a user’s Date of Birth, but I want to display their age. I have a function which calculates the age but I cannot use it in the ItemRenderer and I don’t know why. I don’t think it will work if I use this code outside of the ItemRenderer. The DOB is accessed by {data.dob}.Here’s my code:<s:GridColumn dataField=”age” headerText=”Age” width=”80″><s:itemRenderer><fx:Component><s:GridItemRenderer><fx:Script><![CDATA[// Retrieving the user’s
