An event which fires in ReportViewer after the report is generated

I searched for quite a while to find a way to run a client side script whenever the ASP.Net SSRS ReportViewer control has finished rendering/generating a report.  I could not find one documented but when looking in the report viewers resulting html source I found mention of ClientController.CustomOnReportLoaded which was set to an empty function.  Using the JQuery ready function I was able to attach code to this event and have it run only after the report was generated.

$(document).ready(function () {

document.getElementById('ctl00_ctl00_DefaultContent_AdminContent_reportViewer').ClientController.CustomOnReportLoaded = function () {

        alert('You see this after Report is Generated');
