DataGrid / itemRenderer help
I'm using the itemRenderer example in the help files to
convert the background color of a cell depending on the numeric
value. That all works just fine but I noticed that on the columns I
add that renderer too it makes the cells selectable -- not
editable, selectable. When you roll the cursor over any of the
columns that don't have the renderer on it, the cursor turns back
to an arrow. What do I need to add to the renderer script to make
it non selectable and so the arrow cursor is present? I just don't
want the user to think they can edit the text in the box.
Thanks
After a few hours of messing around and searching I found an
example how to achieve what I was looking for. I used "Label"
instead of "TextInput". A Label isn't selectable but the
backgroundColor isn't something you can change. So "one way" is to
draw in background color, like this -->
package assets{
import mx.controls.Label;
import flash.display.Graphics;
public class CellColored extends Label {
override protected function
updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void
super.updateDisplayList(unscaledWidth, unscaledHeight);
var g:Graphics = graphics;
if (this.text != null){
text = this.text;
g.clear();
if(Number(text) < 2){
g.beginFill(0xCC0000);//red - bad
g.drawRect(0, 0, unscaledWidth, unscaledHeight);
g.endFill();
else if (Number(text) >= 2 && Number(text) <
4){
g.beginFill(0xF4E002); //yellow - okay
g.drawRect(0, 0, unscaledWidth, unscaledHeight);
g.endFill();
else if (Number(text) >= 4 && Number(text) <=
6){
//green - good
g.beginFill(0x009900);
g.drawRect(0, 0, this.unscaledWidth, this.unscaledHeight);
g.endFill();
setStyle("color", 0xFFFFFF);
}

Datagrid itemRenderer - Help needed
I am having trouble getting this little bit of code working. I am trying to build an adhoc SQL generator, where the user selects the list of fields and then is able to set the WHERE criteria in a dataGrid, each row has field, criteria (ComboBox -equals, less than, etc), Low (editable), High (editable-Text or ComboBox lookup), AND/OR static ComboBox. Some of the field selections could be regular text based fields like Name and other fields selected could be lookup fields like State. I would like to be able to on rows that are TextInput render out a TextInput for LowValue and HighValue columns and for lookup fields render out a ComboBox with the dataProvider being set by a call to addComboData.
addComboData simply uses the myDataGrid.selectedItem.fieldname to determine which of the lookup table to use and assigns that collection to CBoxdataProvider. Seems simple enough but I have not been able to figure it out, some modifications seem to work, but only for a single dg cell others give me a list but does not populate lowValue but kill all other renderers. All help is appreciated.
<mx:DataGridColumn headerText="Low" rendererIsEditor="true" editorDataField="selectedItem" dataField="lowValue" textAlign="center">
<mx:itemRenderer>

<mx:HBox horizontalScrollPolicy="off" verticalScrollPolicy="off" horizontalAlign="center">

<mx:TextInput id="lowLabel" visible="{!data.showCombo}" />
</mx:HBox>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>Setting the selected item is not the same as a click. If you created the renderer correctly the style should change when you actually click on the item. (Does it?)
Or are you just trying to get the first row's background to be a different style when the datagrid first shows? (Initialization problem or not working at all?) -

Datagrid itemRenderer/itemEditor trouble
I have a datagrid in a Flex project, the data grid has an XML file as the source (contents below), now due to the way it is formatted (I cannot change this) some of the data I want to display is inside a tag that isnt at the initial array level. Here is the file:
<?xml version="1.0" encoding="utf-8" ?>
<Categories>
<Category>
<CategoryName>Cat 1</CategoryName>
<CategoryLink>http://www.google.com</CategoryLink>
<CategoryData>
<CategoryDescription>This is the description of category 1</CategoryDescription>
<CategoryHeader>My Category Title 1</CategoryHeader>
<CategoryNumber>1</CategoryNumber>
</CategoryData>
</Category>
</Categories>
I need to display CategoryName, CategoryLink, CategoryData.CategoryDescription, CategoryData.CategoryNumber.
Now I blindly dropped the datagrid into the project and bound it to the data source, I get the following returned for CategoryData:
[object CategoryData_type]
Not much use, but with what appears to be a hack I changed the code for the column to read dataField="CategoryData.CategoryDescription", and hooray it works. I didnt realise at the time that this was wrong, and when I dropped in an itemEditor things went wrong. When the datagrids load they display the correct data, but then when you try to edit any of the child property fields you get the following error:
ReferenceError: Error #1069: Property CategoryData.CategoryDescription not found on valueObjects.Category_type and there is no default value.
I have looked up the error and I realise that it means that there is no value for CategoryData.CategoryDescription, but if I can display it why can i not edit it! What do I have to do to make this work?
Anyway, here is the code, it shows the default bound datagrid, a second datagrid with the hack applied, and a third hacked datagrid with an itemRenderer and itemEditor on the number columns
Can you please take a look and tell me what I did wrong, well more to the point, if there is a doc that explains how to deal with XML like this then please point me at it.
I did try changing the return type for ANY of the columns, but this fails, I also tried a labelFunction, but again I can get the [object CategoryData_type] to display, but I get the null reference exception as the datagrid loads if I try to get to the child props.

All and any advice welcome.
ShaineOne last try, I now know for sure that the data in the file is loading, I created a labelFunction on the CategoryDescription column that looks like this:
protected function dispData(item:Object, column:GridColumn):String
var t:Object = item.CategoryData;
var s:String = item.CategoryData.CategoryDescription;
return s;
Because it returns s, which I now know is undefined (which is the problem!) I managed to get a debug output. As you can see the value of t is the categorydata, and it appears to have the 3 values I need to get access to, but I have no idea how to do this. I also changed the function to read:
protected function dispData(item:Object, column:GridColumn):String
var t:Object = item.CategoryData;
var s:String = t.CategoryDescription;
return s;
But this undefines t and s! Very confused

Datagrid itemRenderer custom component formatting
OK, so this is my first attempt at an itenRenderer. This works below, but I have to imagine there is an easier way. There is also a problem with below, where the changed field (datafield=side) after the itemRenderer is applied, the text is all out of format, and there is a kind of selection on row one of that column. Obvisouly, though the translation is happening, I'm either overidding the wrong thing, or I'm doing something totally wrong.
Goal..... Show in the datagrid, the three colums below from date provided from elsewhere. (This all works), but in the 'side' data it comes in, in raw form as either an 'a' or 'b' or 'both', and I'm trying to display that as something more user friendly. So when both is read it changes it to 'No'.
Any help. This seems really easy, though I can't understanading hy my custom function screws with the cell selection, and formating?

Ellipsis (...) in dataGrid itemRenderer
If you want a line of text in a datagrid cell to end with an ellipsis (...) when it's too long for its cell, you can set the column's item renderer to be "mx.control.Label" and that works. The entry looks like this:
Here is my line of dat...
But here's my problem.
I have created my own item renderer which is an HBox containing an image and a label. But the label doesn't truncate with the ellipsis ... when the data is too long, it simply chops the end off the displayed text.
So my question is this. How can I get the ellipsis ... to appear for the label in my item renderer? I'm using a datagrid with scaleable column widths so I can't set a fixed width on the label which would work, I know.
Cheers,
NeilThanks for your suggestion.
It didn't work but inspired me to play around with minWidth and maxWidth.
What I eventually got to work was:
maxWidth="
{this.width-28}"
...on the Label in the HBox. I'm assuming that "this" here refers to the ItemRenderer.
I had to put in the "-28" bit or it wouldn't do it. If you want more padding on the right of the ellipsis (so it doesn't hit the edge of the cell) increase the 28 to something higher. Use a lower value for less padding.
Hope this helps someone else like it did me.
Cheers,
Neil -
Problem with Datagrid itemrenderer with a Datagrid
Hi all,
I have this kind of a structure. I try to use a datagrid item renderer in a data grid column. However when I try to move rows inside the same datagrid I experience a problem. When my datagrid loads first it seems correct, but when I drag and drop a row in the same datagrid inner datagrids start to be drew in wrong rows. I checked the DB but there are no mistakes in DB records. Problem is with rendering. I suppose inner datagrids trying to draw to early or datagrid component is trying to reuse the itemrenderer. I could not find any solutions for that. Any help will be greatly appreciated..

DataGrid itemrenderer with switch statement
Hi,
I have datagrid control with this columns

<mx:DataGridColumn dataField="type" headerText="Type"/>
<mx:DataGridColumn dataField="title" headerText="Title"/>
<mx:DataGridColumn dataField="content" visible="false"/>

Under type column I have values from 1 to 6. Each number presents type of content. I have icons for each type. I would like to show icon instead of just number. I know this can be done using itemrenderes but I don't know how to accomplish this.If this post answers your question or helps, please mark it as such.

You might see issues with this code during scrolling, as DataGrid recycles itemRenderers, but in that case the icon information must be in the data.

Datagrid itemRenderer dynamic values
While working on an application I came across the following
problem. I've got a view with a datagrid, where I have several
columns. Each column needs 2 values displayed beneath each other in
one cell. You make an itemRenderer with 2 labels inside a VBox.
Easy so far. However since this scenario repeats several times it
seems counterproductive to make an itemRenderer for each cell. How
can I make the text property for the labels change for each cell
instead of being static in their values.
Thx in advance.Your description of your requirements and your sample code do
not paint a clear enough picture.
Your dataProvider has 4 pieces of data: batchId,
bookingNumber, valueDate, immsBranch. Your current itemRenderer
references two of those pieces of data, and you say you want to
reference the other two. You can do that easily like this:
<mx:Label text="data.valueDate"/>
<mx:Label text="data.immsBranch"/>
A basic question: will your DataGrid have two rows for each
set of 4 pieces of data? If so then I understand your problem. If
not, then you must clarify exactly how and when you would like the
4 pieces of data shown in your DataGrid.
In any case, you probably need a Repeater, and then need to
figure out how to get at the right data at the right time in the
Repeater.
See this FB 3 help topic and its sub-topics:
Dynamically Repeating Controls and Containers
Also search for this in the FB3 help to see the API:
mx.core.Repeater
You can define a listener for the Repeater for the Repeat
event to specify processing for each iteration of the
repeater. -

...........Everything displays correctly and the popup functions well too.. The only problem is that when you scroll the initial datatagrid, you see data in the column, which calls the itemrenderer, being swapped between the rows. I have tried same on another example and 1) on sorting the column, the popup contains the wrong data and 2) if there are other columns, its only the one calling for itemrenderer which swaps data between its rows.
Any help | Many thanks.. -
DataGrid itemRenderer done in code?
I've searched for info on how to implement itemRenderer for a
DataGrid, and despite seeing some docs and examples, they're all
very different from what I think I want, and what I think should
also be possible.
Here's what I want: for one column (called "alert"), I want
to be able to programmatically display an appropriate image (or
even just render a character, such as "X") based on the data value
of that cell.
I would think it should be something like this:
<mx:Script>
private function RenderAlert(... ? ) :String {
if (data == "delayed") return "D"
else if (data == "canceled") return "X"
</mx:Script>
<mx:DataGrid ...>
<mx:columns>
<mx:DataGridColumn headerText="Alert" dataField="alert"
itemRenderer="RenderAlert"/>
</mx:columns>
</mx:DataGrid>
So, if anyone can point me to an example like this, I'd be
very appreciative. I'm really hoping it's possible, as all the
other methods I've seen illustrated don't appear to handle the
render decisions in code.
Thanks!By default, I'm not exactly sure what each cell is.I'm sure
if we dug into the docs somewhere it would tell us..
I've always done any conditional stuff in my itemrenderer
component.
Specifically in the set data function which you should
override:
i.e the following is a snippet that sets a combobox
itemrenderer in a datagrid. It gets the ID of the current object
being rendered then looks it
up in an arraycollection to get the "english/display name" of
that ID then sets that as the selected item in the combo box
override public function set data(value:Object):void {
yy = this.parentApplication.AC_semesters;
if ((value != null) && (yy != null) &&
yy.length > 0) {
a_course = Course(value);
this.invalidateProperties();
for (var i:int = 0; i < yy.length; i++)
var firstItem:Object = yy.getItemAt(i);
var myid:int = a_course.crs_semester;
if (firstItem.sem_id == myid)
cb3.selectedIndex = i;
so in your case you could make up an itemrenderer component
being a label, then in your set data function, have a conditional
check to set the label.text = "X" if the value passed in is equal
to whatever.
Hope this helps... -
DataGrid itemRenderer column problem
I have searched high and low and have not found a solution so I'm hoping someone here can help me out.
When I start up my application, my datagrid (one of the columns uses a itemrenderer) that column, displays everything but it spills / shows funky, then when I scroll some of them get fixed. I don't know exactly what causes this or how to fix it. The column I'm talking about is the "Like" column.
If code is needed I will provide a pastebin link when requested, and I have attatched a screenshot of what the problem is.
Any help / suggestions would be appreciatedUpgrade to 3.4.

Change one alternatingRowColor of a spark DataGrid ItemRenderer
Hi,
I try to find a way to change the alternatingRowColor of only one spark ItemRenderer. It depends on a property set in an item in the DataProvider and this property can change at the runtime.
How do to this?
Thx.Do you mean to say depending on item value in data provider it datagrid row color should change?
If yes then following link can help to solve your issue:
