Datagrid column value

How do I iterate over each row and then the columns of the
datagrid?
I populate the datagrid columns through an actionscript
function (on click of a button and using datagrid.addItem()
method). So my dataprovider is not an arraycollection or from xml
or whatever.

DataGrid does not have an "addItem()" method.
Are you using Flex 1.5?
Show us the code where you are doing this.

Sum datagrid column values

I am looking for a way (action script code?) to sum datagrid
column values.
I am using Flex2 with Cold Fusion MX7.
I populate a DataGrid by setting dataprovider to the result
of a Coldfusion query.
(this.masterList.dataProvider = event.result as
ArrayCollection;)
This all works fine.
The masterList datagrid has debit, credit, and unitcost
columns. I want to sum those columns individually, and display the
results in text boxes in another panel.
I could run a Coldfusion query to return the sums, but would
like to do it on the client side with action script.
I want to sum them everytime I update the datagrid, so need
action code that I can put in the result function.
I am new to ActionScript, and not sure how to loop through
the array collection(and/or) dataprovider and sum the items.
Any help would be appreciated.
Thanks.

Loop through your array..if the arrayCollection was named
myArray;
private sumFunction():Number{
var sum:Number=0;
for(var i:uint=0;i<myArray.lenght;i++){
sum+=myArray
.debitValue;
return sum;

Hey
to get the multiple selected row use the property datagrid.selectedindices this will return a string with all the selected index with (,) separated .
then get the data of selcted index and put it in to database.

Changing a datagrid column image according to the datagrid column value

Flash Builder 4.5 / SDK 4.5.1.
Fairly new to Flash Builder & Flex
Application targets tablets so it's a "mobile" project.
Been beating my head up against the wall on trying to figure out how to do this. Watched videos on Lynda.com. Read Adobe "docs" till my eyes glaze over. Takes me about 2 lines of code in my corresponding .NET project doing the same thing.....
Tried numerous examples. Inline rendering, external rendering files per the examples.
I have a response field in the database and corresponding column in the s:datagrid. If the "reportInfoResponse" field is null (not answered), show an image with a question mark. If yes show an image with "Yes" on it. Same for a no answer.
I get errors of:
1120:Access of undefined property negativeAnswer.
1120:Access of undefined property affirmativeAnswer
1120:Access of undefined property reportInfoResponse
1120:Access of undefined property showResponseImage
If I put this in an external rendering file I also get an error where it can't access the datafield (reportInfoResponse). I've tried data.reportInfoResponse, {data.reportInfoResponse}, {reportInfoResponse} and just plain reportInfoResponse the external rendering file with no luck. I've tried single and double quotes around Y and N. According to all the examples (not to say there aren't more!), I should be able to reference data.reportInfoResponse in the external file and things should be fine. Of course, the examples are bare bones code and I don't have a clue if any importing of classes or other items need to take place. I never see any references of such. The examples also show the image embedding and changing the image by using imageID.source=... In my code it tells me it can't find it.
I have put (ERROR HERE...) on the lines where I'm getting the error messages. I've eliminated a lot of database scripting and such cause that's all working.
Any and all suggestions would be appreciated as I'm pulling out what little hair I have left.......and that's not much at my age........ And yes, I probably could do it by just show text in the column, but that's not what the customer wants... There are other columns I need to do this for so I figure if I can get 1 done and working, the rest are a snap. I CAN use inline or external rendering to show an image. It's the changing it that is the catch.........
Thanks in advance!

Ioan Thanks for the reply.
Probably my previous explanation of the problem was a little incomplete. Let me give a better description.
The situation is something like this.
I have a requirement in which the customer wants the column header to reflect the 'keep filter value' restriction that he does dynamically in the query report.
i.e:
-- usually the kf column header shows 'sales volume'
-- column header with text variable of the Calender year / month variable -- 'sales volume for 2000 oct'
-- but when the report is run, if the user wants to go and change the filter: calender year / month > rt clk > keep filer value > select Jan 2003.
The kf column header still shows 'Sales Volume 2000 Oct'
How to make the column header change to 'sales volume for Jan 2003' ?
Any suggestions greatly appreciated.
Thanks,

If myText.text == any value in a datagrid column

Hey guys, in a simple form, I am trying to achieve what's in my title.
I have a text box in which you type in a value (number).
I have a submit button which inserts the value into my data-grid which is populated by a data provider to display that information (ZendAMF).
For my submit button function I need it to loop through all the values(rows) in a column (my dataprovider) of my data-grid to check if my text box value is equal to any of the data in the rows for that column.
I found a function on another forum that should help me achieve this but I still cannot get it to work as I don't think I'm using the function correctly. Note the function is called "findItem()"
Here is my example code:
//I have a datagrid
<mx:DataGrid id="myDataGrid" dataProvider="amfcall.getData.lastResult}">
 <mx:columns>
 <mx:DataGridColumn headerText="MyHeading" dataField="myDataField"/>
 </mx:columns>
</mx:DataGrid>
//I have a form for adding data into the datagrid
<mx:Form id="addData">
 <mx:FormItem>
 <mx:TextInput id="myText"/>
 </mx:FormItem>
</mx:Form>
//I have a button to submit the form data by calling a function
<mx:Button label="Add" id="addData" click="findItem()"/>
//I have the function to find any item in the datagrid column that is equal to the text input in the form. This is what I can't code correctly.
public function findItem(myDataGrid.dataProvider, myDataField:String, myText.text):Boolean
 for each(var item:Object in myDataGrid.dataProvider)
 if(item[myDataField] == myText.text)
 return true;
 return false;
So I don't think I'm correctly typing the first line of the 'findItem' function as I'm currently receiving [I]1084: Syntax error: expecting rightparen before dot.[/I] for this line [I]public function findItem(myDataGrid.dataProvider, myDataField:String, myText.text):Boolean [/I]
Also, the error does not change if I strict type those things to ':Object' etc.
I may just be using the function totally wrong, can anyone hlpe me out?

Hard to tell what’s going on from the information you are providing; but just looking at the first line of your sample code:
Have you checked in the debugger to see what your dataProvider looks like?
You want a resultHandler to set some kind of list – let’s say a previously declared AC, which then becomes your dataProvider for the DataGrid. Something like:
private function amfCallResultHandler(event:ResultEvent):void{
 Var someVar:ArrayCollection = event.result as ArrayCollection;
 blah blah blah;
 myDataProvider = someVar;

Need help adding image to datagrid column

Hi,
Can anyone tell me how to add an image to a datagrid column?
I have created a flex library project which contains a mxml component with a datagrid, an item renderer mxml component which rendered the image within the datagrid column depending on the value coming back from the database for that column and a folder 'assets' which hold all the images. When I add the library to my main project and call the mxml component with the datagrid an image place holder is visible in the datagrid column but not the image. However, if I take the image out of the library project and added to an 'assets' folder in the main project the image is displayed in the datagrid column.
It looks like, even though the images are in the flex library project and only the flex library project is trying to display the images in the datagrid, the library project is looking in the main application project folder for the image.
Does anyone know why this is happening and how to fix it?
Thanks in advance for an help,
Xander.

I have tried embedding the images in my library but it still didn't work. Also I can't embed the image as I'm using the value of the column to complete the image name, for example in my mxml item renderer component I have the added the following code
<mx:Image source="@Embed(source='assets/' + data.mycolumnvalue + '.png')" tooltip="{data.mycolumnvalue}"/>
but nothing is displayed.

How not to sort datagrid column on double click

Hello,
I am currently building an application containing a datagrid for data representation. I've created a custom datagridheader in order to add a input text for filtering the columns (see code below).
My goal is to hide the textinput, and then show it on a double click on the header. So i would like to know how to avoid the sort of this column each time i double click.?

Based on your idea, i've intercepted the click event and I use stopImmediatePropagation.
THen i added an image to sort the column. So if the image is clicked the sort is ok.

Editable Datagrid Column

I have to make a datagrid column editable during runtime based on the data. If the column has a specific data then the column should not be editable otherwise it should be editable. Can we do it in flex ? please show some pointers.

I don't have any examples , but you should probably have a custom itemrenderer for your datagrid which contains a textarea. In the itemrenderer should override set data( value:Object ):void. In that function you check a condition to see if the textarea "editable" value should be set to true or false. Below I have some pseudo-code.
<s:Itemrenderer>
override public function set data( value:Object ):void
if( object.decidingValue > 0 )
TnA.editable = false;
else
TnA.editable = true;
<s:TextArea id="TnA" />
</s:Itemrenderer>
or you could just put the code in the TextArea declaration
<s:TextArea id="TnA" editable="{data.decidingValue > 0}" />
(TextInput area is probably more appropriate than a textarea , but the logic is the same )
If this response was helpful please mark it as such.

ItemRenderer in a datagrid column setStyle() does not do anything to the appearance

I have a custom ItemRenderer in a datagrid column, however
the setStyle() does not do anything to the appearance. when it is
called. Any ideas?
<mx:DataGridColumn dataField="area" width="50"
headerText="Area">
<mx:itemRenderer>
<mx:Component>
<mx:Text>
<mx:Script>
<![CDATA[
override public function set data( value:Object ) : void {
super.data = value;
setStyle("Color",0xff0000);
if(data.area == 'G'){
setStyle("backgroundColor",0xff0000);
}else{
setStyle("backgroundColor",0xff0000);
]]>
</mx:Script>
</mx:Text>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>

Your renderer code looks a little strange. This works, and
may get you started:

Different flex components based on AdvancedDataGrid column value

I have the following code snippet, here I am able to change the label of the button based on the Data Grid's Column value. I am unable to think of a way where I can add two completely different buttons, based on Data Grid's value. Any help will be greatly appreciated.

Datagrid column text styles

I have a datagrid column that contains strings in this
syntax: ##% (##%)
When the percentages are over 0% I'd like the text to be
green; when the percentages are under 0%, I'd like to change the
text to red. Apart from breaking this into two columns, how can I
change the colors of different strings inside the same datagrid
column?
Thanks,
Tom

Tom,
One way to do this would be to make a custom ItemRenderer
based on a Label for your dataGrid column. Then, just test whether
you have positive or negative values for your dataField. If it is
negative, use a setStyle('color', 0xFF0000) for red. Here is a
basic example:
<?xml version="1.0" encoding="utf-8"?>
<mx:Label xmlns:mx="
http://www.adobe.com/2006/mxml">
<mx:Script>
<![CDATA[
override public function set data(value:Object):void {
super.data = value;
if (value != null)
if(value.fieldValue >= 0) //fieldValue will need to match
your dataField value from your dataProvider of your dataGrid. You
might need to convert it to an int to compare.
setStyle("color", 0x00DD00);
} else {
setStyle("color", 0xDD0000);
super.invalidateDisplayList();
]]>
</mx:Script>
</mx:Label>
Then in your main app:
<mx:DataGridColumn headerText="Drill Type"
dataField="fieldVAlue" width="105"
itemRenderer="renderers.RedGreen"/>
This assumes that your mxml component is named
'RedGreen.mxml' and is in the 'renderers' directory. You can adjust
this to fit your project as needed. I hope this helps.

Adding a Tree into a datagrid column

I have a requirement where I have to create a datagrid with
one of the columns having a tree control. The problem I am trying
to resolve is how to dynamically change the height of the datagrid
column which has the tree when the tree is collapsed and
dynamically increase the datagrid column height when the tree is
expanded.
Is is feasible ? Am I chasing a wild dream ?
Any help will be greatly appreciated...
Thanks

Darin,
Thank you for responding. I was able to get a tree display in
a datagrid. I am going to attach all the code.
The problem I am facing is, I need two clicks to expand a
tree in the datagrid column so that both the tree to expand and the
datagrid column to adjust its height. Let me know why this is so.
May be, being a newbie, I am completely off the track here. Thanks
in advance.

Show dataTip on a datagrid column

Hi,
I need to show dataTip on a datagrid column only if its length is greater than 20 chars.
Additionaly, my datagrid is a custom component, I am passing the column names as an array and building the grid dynamically
so that it could be used for any dataprovider (with different set of columns).
when the dataTipFunction is invoked runtime I would not know the column field name
to access the value since the dataTipFunction makes available only the item:Object unlike labelFunction which provides both item and column.
But i would know all the column names at any given point in time.
Is there anyway we can get hold for which column the dataTipFunction is being called for...
Any help is greatly appreciated.

Subclass DataGridColumn and add the dataTipFunction to the subclass. Then
the 'this' pointer will be the column.

DataGrid column width is not set properly

Hi,
 In the below example I has called the OptimizeDataGrid method on Button Click event to resize the Column according to the data. First time of the button click event it called the function whereas the Datagrid Column width alone is not set properly.whereas on second time it is working properly.
For Eg : In the below statement the text value is coming as 55 and widthPadding is comes as 25. but the sum of these two value is not in the dg.columns[col].width.
dg.columns[col].width = text + widthPadding;
But the same is working on the second time of the Button click event. is any help me out to resovle this issue. Thanks in Advance.

With horizontalScrollPolicy="off" (the default), it is hard to control
column widths because the columns are sometimes overridden to make sure they
fit on the screen.
