Flex :: Data Passed From DataGridColumn.itemToLabel To DataGrid.itemRenderer.set(data)?
Dec 4, 2009
I have a DataGrid whose dataProvider is an Array of int Arrays (each with different lengths). Since each row has variable size (and I want to display all the data), I decided to extend DataGridColumn and overwrite the itemToLabel function to be able to display the data. The problem is that I also need to display the data differently depending on the int value.
I believe the only solution is to write an itemRenderer, but the only input the itemRenderer.set(data) function receives is the entire int Array. I believe I need either the exact string returned by itemToLabel or the column index of the cell the itemRenderer is for (to basically do the same parsing I implemented in itemToLabel).

Is it possible to put an itemrenderer on the DataGrid itself rather than a datagridcolumn? I could only find examples for datagridcolumn. I want a generic itemrenderer on all the items in a datagrid...

I'm trying to reach the dataField of a DataGridColumn in the itemRenderer. Below is the dataGrid:
<mx:Script>
<![CDATA[
[Bindable] public var weeksOfMoth:ArrayCollection = new ArrayCollection([
[code].....
In the set data function of the itemRenderer, I receive an entire week (which is ok), but the itemRenderer doesn't know which day to use because the dataField is unknown. Does anyone know how to reach this dataField in the 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?

I've got a DataGrid in my mobile application (I know, I know but there's currently not other solution for this), that numeric values. Depending on the value of a cell, the text gets colored. My big issue is that this doesn't work very for more than about 5 rows of data. I reckon the issue is that the set text function (in which I format the color) can't keep up with the amount of cell changes and formats the text based on the last updated cell of the row.I thought about a column item renderer so that the renderer only gets the value for that column, and not the whole data of the row.
Just for reference, this is my current item renderer (again, this works fine for few rows, for 5+ of fast changing data, this doesn't work any more, cells get formatted even though their data hasn't changed).[code]I just double-checked and have to revert my previous statement. A single row works fine, the second row already messes up the color formatting though. It seems as if the datagrid somehow throws together the values.
Doing the color formatting in the set data method shows the exact same effect;[code]My assumption about the grid messing up the ItemRenderer's data seems to be correct.A simple trace in the set data method (trace("old: " + _oldVal + "new : " + value[column.dataField]);) revealed that somehow, values of the next grid row (in case there are 2) get used as well as _oldVal gets the old value of the next row.

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 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.

I've got a Gridcolumn in a Datagrid (Spark). The Column's dataprovider is a Number value that gets updated via Binding.Now, without an item renderer the cell displays the correct values.If I set an item renderer, I can't access the values in this renderer.My renderer looks like this, so nothing really do here (for now) but to trace the value, but the value is always NaN.
<?xml version="1.0" encoding="utf-8"?>
<s:GridItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark" width="100%" height="100%" >[code].......
without the renderer, the column displays the correct values, so apparently the DefaultGridItemRenderer works fine.As requested, here is my Datagrid;
<s:DataGrid id="dataGrid" dataProvider="{_listItems}">
<s:columns>
<s:ArrayList>[code]..........
_listItems is an ArrayList with instances of a model class, which has (amongst others) a property called change of type Number.

I 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).

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 would like to let the data provided to a DataGrid decide how best it should be rendered (that is, let the data carry with it an object which will do the rendering).For example, by creating a "Renderable" interface, which has a 'renderer:IFactory' property, then used as below:
<mx:DataGrid x="0" y="0" width="100%" dataProvider="{myDataProvider}">
<mx:columns>
<mx:DataGridColumn headerText="Task" width="100"[code]....
But to do this, Renderable has to extend IEventDispatcher, which seems like a little much...I've also tried using:
itemRenderer="{(data as Renderable).getRenderer()}"
Which does nothing (in fact, the getRenderer method never gets called).Is there a better way to do this? Am I doing something fundamentally wrong?

I was wondering what the difference between data and listData in itemRenderers in flex. I have worked with data in all of my itemRenderers.
Basically I want to know when to use which, where each gets set and if I can use them together?
Note that I am asking from a Flex3 point of view.

How do I differentiate between a data provider update and a itemrender being recycled when using a custom itemrenderer in a DataGroup?I have overridden the set data function of the custom item renderer, but I have found that on making a change to the ArrayCollection used as the DataProvider some of the item renderers are not assigned the same object they had before the update. This has made it almost impossible for me to distinguish between a data update and an itemrender being recycled. Also, the data never seems to get set to a value = null, so that seems to be out as well.

Ok, here's my requirement in short-I have a datagrid that is updated every time data update is received. Now, all I want to do is check if the present value in every cell in a specific datagridcolumn is less than the new value then color that particular cell green, if the present value is greater than the new value then color it red, else leave previous color as it is. Simple?Now, the coloring part is important but comes later. As of now, I need to know how to get present cell data in the labelfunction of the datagridcolumn.
// column is a datagridcolumn
column.labelFunction = function(oData:Object)

For poor performance reasons, the DataGrid will cache checkboxes and reuse them for different rows. If you have 50 rows, it won't create 50 checkboxes. It will create as many checkboxes at are visible, plus a few more for padding, and then reuse them as you scroll. This is why you need to explicitly manage their state. How can improve it ? How can fixed checkbox value ? i used checkbox like below But checkbox doesnot remembering the values

how can I refresh the displayed data in a Datagrid when the underlying ArrayCollection changes?
<nmoschitz:dataProvider>
<mx:HierarchicalData source="{arrCol_groupedData}"
childrenField="accounts"/>
</nmoschitz:dataProvider>
Calling a simple refresh (like with a simple arraycollection as a dataprovider, or with a refresh on the Grouping Collection) does not work. Also re-assigning the arrayCollection to the Hierarchical Data and then assigning this one again to the Datagrid does not work (even with calling invalidateProperties() or validateNow()).

I have an editable DataGrid in Flex, with data full of numbers. The columns have no special itemRenderer, but a labelFunction, which returns the number as-is if positive, but puts it in parentheses if it is negative, like so
27.3 => "27.3"
-27.3 => "(27.3)"
Now, these cells are editable. When I try to edit a cell with a positive number, nothing is wrong. But if I try to edit a negative number, it starts editing (27.3) instead of editing -27.3. Because of this, when the edit is done, the labelFunction is evaluated with the new value in parentheses(i.e.,labelFunction is called with "(30.5)"), and converting it to a Number results in NaN. So, I want to know if I can make the DataGrid edit the data in the dataProvider instead of the label that it shows.
