I have a DataGrid with 3 DataGridColumns. All 3 of them have separate dataFields.I need to get the datafields into an ArrayCollection and pass it to a funciton. I dont want to hard code the ArrayCollection.
View 1 RepliesComing back to flex after not using it for a while, trying to load some xml (generated by php) into a datagrid using dataprovider to create a simple grid showing the daily high and low temperatures over the course of a week. I can get the data to display in my datagrid, but the columns are loading in random order. (So friday is coming before monday etc.) How to assign specific data to specific datafields.
Here's the flex code; (updated to working code. Note that the dataFields simply contain the names of the xml tags and/or the names of the tags within those tags)
<?xml version="1.0" encoding="utf-8"?>
<fx:Declarations>
<s:HTTPService id="weather" url="[URL]" result="weather_resultHandler(event)" fault="weather_faultHandler(event)" />

I'm new to Flex and am using TileList bound to an ArrayCollection. The array collection is empty at load time, and then updates with the results from am HTTPService call. The problem is that the item renderers aren't being rendered as expected, I'm guessing because there was no data when they were first rendered at load time. Here's simplified example:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" >

I am using a custom componenet based off of text as an itemRenderer for a dataGrid that is displaying an XMLList. I want to be able to re-use this itemRenderer for multiple columns, how do I access the dataGridColumn so I know which field to assign to the text value?
super.data gives me the whole XML item, super.parentDocument gives me the whole DataGrid

View 2 RepliesI have a datagrid that I want to add a column of radio button using AS3 (instead of mxml). I was able to do this with a custom itemRenderer.
var dgc:DataGridColumn = new DataGridColumn();
dgc.itemRenderer = new ClassFactory(com.mypackage.RadioBtnColumnItemRenderer);
In my RadioBtnColumnItemRenderer.mxml, I have a box with a radioButton... like so:
<?xml version="1.0" encoding="utf-8"?>
<mx:Box xmlns:mx="[URL]" horizontalAlign="center" verticalAlign="middle">
<mx:RadioButton id="btnRadio" groupName="btnRadioSelect"/>
</mx:Box>
When I run the application, the radio button shows up in the column as it should. However, I cannot select just ONE of the radio buttons. I am able to select all of them, but I don't want this... I want the ability to select one and then if I select another one, then the first one is unselected and the current one becomes selected (just like you would expect radio buttons to work).
How can I validate the cells in a DataGridColumn individually? (ActionScript 3.5) The validation is configured per-cell, based on fields in the given row. For example

I have an itemrenderer used by multiple datagridcolumns and I need to have some condition in the itemrenderer based on the headertext of the datagrid column. Can I access the headertext property from within the itemrenderer?
My itemrenderer extends the LinkButton control and implements the IDropInListItemRenderer interface.

I can't see a way to get rid of certain borders within a DataGrid. I'd like to eliminate a side border on 2 of my columns so that they appear to look like a single column.I'm trying to implement a "clear value" button on each of my DataGrid rows. I was able to have a button show on a custom ItemRenderer from a separate ActionScript file, but I was unsure how to have the button click event propagate to the mxml file where the DataGrid is located. It would be much easier for me to have an extra unresizable column with a 'clear' button.
So, to reiterate: Is there any way to change the border style or eliminate certain borders of a DataGridColumn?
I have a DatagridColumn in flex with two names, TYPE and NAME. Now, when I am sorting a datagridcolumn, TYPE, it sorts the type using sortcomparefunction and gives the result which contains grouped and sorted order of elements. Ex. if I sort for type I get elements in pdf, doc, ppt in grouped order, but they are internally not sorted, ex: for the pdf part, I have elements such as:
TYPE NAME
pdf A1.pdf
pdf X2.pdf
pdf B1.pdf
Here the filetypes are sorted, but for a particular filetype, the elements are not, please notice that B1 occurs after X2, which should be sorted. Is there a way I can sort the second datagridcolumn after sorting the first one according to filetype extensions? I am using sortcomparefunction for sorting the elements according to type , which works fine. The signature is:
private function sortTheTypeColumn(itemA:Object, itemB:Object):int
I have the following datagrid:
<mx:DataGrid id="question" x="9" y="289" width="100%" height="54" visible="{false}" >
<mx:columns>
<mx:DataGridColumn dataField="ans1" headerText="ans1"/>[code]..........
I need to access the data pointed by the dataField, and bind it to a label, but i don't known how to get it.
<s:Label id="debug" x="575" y="106" width="56" height="35" text="{data_from_coloumn_grid_ans1}" />
Is it possible to display a multiline string in a Flex DataGridColumn?i.e. Display:
Text line one.
Text line two.
I've tried putting "
","
"," " when storing the string but nothing seems to work.Currently only "Text line one." is displayed and the rest is hidden in the cell. I would prefer not to use "wordWrap=true" to emulate this behaviour in the cell, but instead be able to manually put in newline breaks (although I could turn on wordWrap to avoid long text from hiding due to cell dimensions).
I extended the DataGridColumn because I wanted to include a custom itemToLabel function (to be able to show nested data in the DataGrid. See this question.
Anyways, it also needs a custom sorting function. So I have written the sorting function like so:
private function mySortCompareFunction(obj1:Object, obj2:Object):int{
var currentData1:Object = obj1;
var currentData2:Object = obj2;
[Code].....
Whenever I try to sort the column, I get the error "Error: Find criteria must contain at least one sort field value."
When I debug and step through each step, I see that the first few times, the function is being called correctly, but towards the end, this error occurs.
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>

// Cannot access arrFiles from here.
[code].....
I have a Datagrid thats being populated by different Arrays... (headers/columns change for the same DataGrid)... I would like to Select a Column of the Datagrid after it was generated by the Dataprovider and Bold it, and place it as the 'last column"
This is what I have.... and throwing an error:
private function populateGrid(evt:Object):void {
dg.dataProvider = evt as Array;
if (dg.columns.length > 0) {
for (var i:int = 0; i < dg.columns.length; i++) {
if (dg.columns[i].dataField == '_user_total') {
DataGridColumn((dg.columns[i].dataField)).setStyle('fontWeight', 'bold');
}}}}
This way I would like to have One Datagrid (for different Arrays) )without having the Columns fixed and declared (like in MXML), but dynamic, and would like a 'specific' column to be Bolded, and placed as the last column, in this example, the column with dataField _user_total.
I have a datagrid that uses an array of objects as the data provider. The objects are essentially key/value pairs:
{ foo:"something"}
{ bar:"hello"}
{ caca:"lorem"}
The datagrid has 2 columns. The first column is the key and the second column is the value. Right now my grid looks like:
My dataFormatter function makes sure that depending on the column (i.e. the dataField value) the correct key or value gets printed out. This works fine for displaying. However, as soon as I try and edit the value field it essentially adds a new value into the object with a key of '1'. For example, if I edit the {caca:"lorem"} object it will then contain the value {caca:"lorem",1:"new value"}.
Is there any possible way I can set the DataGridColumn so that when I edit a value it will update the value associated with the key rather than inserting a new value? I've tried using a custom item editor but it still does the insert. It seems like I need to be able to update the 'dataField' with the actual key value but I'm not sure how to do that.
[code]I am trying to define a DataGrid such that the row nodes will represent new rows in the DataGrid and the column nodes will be used to auto-populate the DataGrid's columns. I am having a problem setting the dataField for each of the DataGridColumn ojects created.The DataGrid is created but the cell values for row 1 are all 0.51 and row 2 are 0.61.
View 1 RepliesIs there anyway to create a custom item editor based on the dataField value? For example:
<mx:DataGrid editable="true" dataProvider="{_actionArr}" id="prop">
<mx:column>
<mx:DataGridColumn headerText="Component" editable="false" dataField="label"/>

How can I add buttons in second column using an ItemRenderer?
On my flex (flash builder 4) DataGrid - DataGridColumn , I have set a custom itemRenderer
itemRenderer="myComponents.EncounterDGItemRenderer".
My renderer is a Label
public class EncounterDGItemRenderer extends Label
I found that my tooltips (datatips) stopped working once I started using this custom renderer. I also found that I can set the tooltip on the label in the
override protected function updateDisplayList
by setting:
toolTip=data['addedDate'];
This works find, however the problem is I need to choose a different data field based on the column. I was hoping for something similar to how a DataGridColumn labelFunction works - where I have access to "column.headerText" or "column.dataField". However I only have access to the underlying data object, not the name of what is being displayed (unless I am missing something).
Is there a way in a data grid item renderer to know what the column header text is, or do you have a different approach?

View 2 RepliesI have a advanced datagrid and populating some data by using arraycollection. And i am filtering the arraycollection, the arraycollection index got changed.
Arraycollection:- [0] - name: abc
[1] - name: hello
[2] - name: hello1
[3] - name:hai
after filtering the arraycollection as 'hell' , the array collection is displaying like the below:
Arraycollection:-
[0] - name: hello1
[1] - name: hello
Can i know the reason why the index got changed after filter it?
* no server side code for filtering. it is only flex side filtering.
i have a problem using the itemRenderer functionality. When using an ArrayCollection the visible Data in the DataGrid using the itemRenderer will be rendered just fine. But if i start scrolling the entries are repeating in the cells using the renderer. The cells are not filled with date according to the id. What mistake i'm doing here.
I read a lot of the explainations like:
