Hi,
You can take help of following code :
<?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:Declarations>
<!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>
<fx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
[Bindable]
public var Arr:ArrayCollection = new ArrayCollection([{a:"AAA",b:"BBB"} , {a:"111" , b:"222"}]);
public function enable():void{
Btn.enabled=true;
]]>
</fx:Script>
<mx:DataGrid x="91" y="36" dataProvider="{Arr}" click="enable()">
<mx:columns>
<mx:DataGridColumn headerText="Column 1" dataField="a"/>
<mx:DataGridColumn headerText="Column 2" dataField="b"/>
</mx:columns>
</mx:DataGrid>
<s:Button x="210" y="237" id="Btn" label="Button" enabled="false"/>
</s:Application>
