I've found if you set the "Pager style" to "Custom", you can add <xp:pagerControl> controls which have onclick events associated with them. However, I cannot get any event (client or server) to fire off.
<xp:pager id="pager1" for="repeat1">
<xp:pagerControl id="pagerControl1" type="Next">
<xp:eventHandler event="onclick" submit="false">
<xp:this.script><![CDATA[alert("hello");]]></xp:this.script>
</xp:eventHandler>
</xp:pagerControl>
</xp:pager>
The "hello" alert box does not show onclick of the "Next" link in the pager control. Am I missing something?
