ActionScript 3.0 :: Accessing The DataGrid From Inside The Renderer?
Jul 3, 2009
I have created an renderer to modify the content of one of the columns of the DataGrid.
Code:
package {
import fl.containers.UILoader;
import fl.controls.listClasses.ICellRenderer;
[code]....
but how can i access the parent DataGrid or anything outside of this class ?In Java it can be done, but how can i pass any value to this class. My use case is that i click on a delete button and the row is deleted, impossible to do if i cannot access the parent DataGrid and call methods to work with it.

I am developing a coverflow application where I have populated a data grid from an xml file. Now when I click on the cover flow , it generates a pop up with a result drawn from a random number generate function.This random number matches with the index of the data grid and displays the row in the pop up. I could not access the text inside the row. How to do it?

I'm creating Datagrid dynamically and giving each row's first column a custom checkbox cellrenderer as noted here: [URL]. I have added an ITEM_CLICK event listener to the datagrid as such:
Code: datagrid.addEventListener(ListEvent.ITEM_CLICK, ToggleCheckBox); However, for the life of me I cannot figure out A) how to target the CheckBox specifically, B) how to toggle its' selected value, and C) how to finally update the datagrid view to reflect the toggled option.
Code:
private function ToggleCheckBox(e:ListEvent) {
// do some magic
}

Within a DataGrid, I have a DataGridColumn that uses a custom component as the item renderer. Within the component, I have an ArrayCollection that stores a set of value objects. My problem is that I cannot access the ArrayCollection values from outside of the item renderer component. Does anyone know how it would be possible to do this? I have posted a code snippet below.
<mx:Script>
<![CDATA[
// Cannot access arrFiles from here.

I'm trying to create a Flex DataGrid where the firstname and lastname are shown under each other, but in the DataGridColumn
Ideally I would want to do something like
<mx:columns>
<mx:DataGridColumn headerText="Column 2" dataField="time"/>
<mx:DataGridColumn headerText="Column 2" dataField="firstname,lastname" itemRenderer="renderers.FirstNameLastName"/>
so that both values get passed to the itemrenderer, is this possible?

I have to put 2 numeric stepper components in one column of a datagrid. I suppose I need to write my own item renederer code for that. How to write a code for putting 2 numeric stepper components in one coulmn of datagrid.
The 2 numeric steppers would work as time (Hour and Min) components. I cannot use readily availabel time components, and hence have to write something of the above for my own time component.

I have a page (below) that has a datagrid that lists "item"'s returned from an XML file (below) and when it loads it created a page in the viewstack for each item it finds (working) it also renders a page (below) inside each panel but i am having issues passing the data. Each page renders and loads but with the FIRST result of the XML data instead of each page having its own data they all have the same as the first page.
HomePage.mxml
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml"

I'm using a data grid with an item renderer that creates a toggle button. The idea is to have a list of items and only allow one to be selected and pre-select one at start.I've got the single button selection working, meaning that when I click on on toggle button, the others are deselected.My problem is to create a way of pre-selecting an element of the data grid or simulate a click on a row and selecting the corresponding toggle button.If I use the datagrid.selectedIndex the result is a selection but the toggle button doesn't get selected.Here is the code exampleIn this example I am using the array value "selected" to define selected button, not my favourite solution but the one that worked first.The array collection:
public static const ValuesList : ArrayCollection = new ArrayCollection(
[
{ID:0, Name:"One", selected:false},

I have a cs3(AS3) datagrid component and I'm tracking which row the user has selected by using ListEvent.ITEM_CLICK to listen for a selection and then event.rowIndex in the handler function and using this index no to select data from the array which was used with the dataProvider. The problem is this. If the user re-sorts the rows using the column headers, this resets the rowIndex (ie the first entry is always row 0) and so this no longer relates back to my array. Is there a way to directly access some or all of the data in the row the user selects?

I am trying to put a combobox inside a datagrid. I managed to get it this far:
[URL]
Shown in that image is my combobox, populated with data. The problem is that if I set the selectedIndex of the combobox to whatever value is in the corresponding cell, the user can no longer change the value of the combobox. What I mean is, you click on the combobox, a list appears to select from, but you can not select any item in that list.
Here's my code:
Code:

In my game currently I have a series of UILoaders which can be set to load a specific swf file inside the larger one. What Im trying to do is manipulate the 'child' swf file from the parent- in particular use the goToAndPlay() function. Im pretty sure Ive seen the solution before but I cant find it now.
How make the connection from the UILoader class to its contents as a movieClip?

I'm programming an AS3 application where I'm loading an external SWF file to a movie clip in my stage:
var bgLoader:Loader = new Loader();
var bgURL:URLRequest = new URLRequest("file.swf");
bgLoader.load(bgURL);
addChild(bgLoader);
My question is this: how can I read a variable inside the embedded swf (probably through the bgURL, but I can't figure out how)
