<script type="text/javascript">
    	$(document).ready(function() {
    		panelsLoaded = 1;
    		Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(PageLoaded)

    		for (var i = 0; i < panelsCreated.length; i++) {
    			console.log("Panels Updating: " + panelsCreated[i].id);
    		}

    		var panelsUpdated = args.get_panelsUpdated();
