How can I get and set contents of a particular cell in Flex DataGrid? e.g. myDG.Cells(col,row) should return me contents of Cell at [col] Column.
I have some function
private function updateCells():void {
In my Flex DataGrid I have 7 columns out of which 4 has been binded with dataFields but rest of the 3 need some calculation done on the basis of those 4 columns.
I call updateCells function on creationComplete event of the myDG (My DataGrid).

Any help would be appreciated. Thanks a ton in advance.

You need to look at this differently, the DataGrid just displays data from a list/array. Setting one cells value is done by setting the value in the object
the DataGrid is bound to.

Below is how I would handle a simple Cost Quantity TotalPrice grid. Hopefully it might provide you with some help.

<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="" layout="absolute" creationComplete="init()">




           import ee.Order;    // importing your custom class

           import mx.collections.ArrayCollection;


           // build example class Order collection

           [Bindable] // make sure its bindable

           public var egAC:ArrayCollection = new ArrayCollection;


           public function init():void // this is just to make up some data


               var x:int;

               for ( x = 0; x < 4; x++ )


                   var newOrder:Order = new Order(); // initialize new Object of type Order


                   newOrder.Quantity = 0;

                   newOrder.Cost = ( x + 2 ) * 2 / 2;   // making up costs

                   egAC.addItem( newOrder ); // add order to array collection








   <mx:DataGrid dataProvider="{egAC}" editable="true">


            <mx:DataGridColumn dataField="Cost"  editable="false"/>


            <mx:DataGridColumn dataField="Quantity"/> 

            <mx:DataGridColumn dataField="TotalPrice"  editable="false"/>





// this class is in src/ee folder

package ee


    public class Order


        public var Cost:Number;

        public var Quantity:Number;

        public function get TotalPrice():Number        // getter function


            return Cost * Quantity;
