Item Renderer in AdvancedDataGrid:

In this example you can see how we can use a item renderer property in AdvanceddataGrid control.

The tag of item renderer property is:
<mx:rendererProviders>
<mx:AdvancedDataGridRendererProvider
dataField="SubjectMarks"
renderer="chartrendererinadvanceddatagrid"
columnIndex="0"
columnSpan="0"/>
</mx:rendererProviders>

It has the following property: column, columnIndex, columnSpan, dataField, depth, renderer, rowSpan. In this example we use a pie chart as a item renderer and displayed in AdvancedDataGrid.

Example:

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

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

xmlns:s="library://ns.adobe.com/flex/spark"

xmlns:mx="library://ns.adobe.com/flex/mx"

minWidth="955" minHeight="600">

<fx:Script>

<![CDATA[

import mx.collections.ArrayCollection;

[Bindable]

private var student:ArrayCollection= new ArrayCollection([

{Name:"Amit", TotalMarks:317, children:[

{SubjectMarks:[{Marks:68},{Marks:62},{Marks:74},{Marks:56},{Marks:57}]}]},

{Name:"Sumit", TotalMarks:297, children:[

{SubjectMarks:[{Marks:50},{Marks:60},{Marks:62},{Marks:70},{Marks:55}]}]},

{Name:"Reena", TotalMarks:340, children:[

{SubjectMarks:[{Marks:76},{Marks:71},{Marks:73},{Marks:55},{Marks:65}]}]},

{Name:"Bikrant", TotalMarks:382, children:[

{SubjectMarks:[{Marks:82},{Marks:61},{Marks:75},{Marks:87},{Marks:77}]}

]}

]);
