How to do data paging with LiveCycle Data Services:

sample.mxml:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns="*"
    backgroundGradientColors="[0x000000,0x323232]"
    applicationComplete="ds.fill(items)" viewSourceURL="srcview/index.html">

    <mx:ChannelSet id="channelSet">
        <mx:RTMPChannel id="rtmpChannel" url="rtmp://tourdeflex.adobe.com:2037"/>
    </mx:ChannelSet>

    <mx:DataService id="ds" destination="paged-census" channelSet="{channelSet}" autoSyncEnabled="false"/>
    <mx:ArrayCollection id="items"/>
    <CensusEntry/>
        
    <mx:Text width="100%" color="#FFFFFF">
        <mx:text>The total size of the data set is 500 rows. The page size is set to 100 rows. If you scroll down, you may notice a very slight delay when
        a new page is being fetched.</mx:text>
    </mx:Text>    
    
    <mx:DataGrid dataProvider="{items}" width="100%" height="100%"/>  
    
</mx:Application>
