    <p>I'm using a Google Maps plugin, and I want it to show up on the page load as well as all postbacks. It seems to only work on postbacks though. Any ideas? I have the body onload tag as "body background="#ccccff" onload="initialize()"", but the function is not defined the first time. Why? Here is the code:</p> <pre><code>&lt;script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"&gt; &lt;/script&gt; &lt;script type="text/javascript"&gt; var mostRecentInfo; function initialize() { var center = new google.maps.LatLng(0, 0); var mapOptions = { center: center, zoom:1, mapTypeId: google.maps.MapTypeId.SATELLITE }; var map = new google.maps.Map(document.getElementById("map"), mapOptions); var posStr = &lt;%=JSON%&gt;; if (posStr.toString() != "0") { var test = posStr.toString().split(','); var groundstation = &lt;%=groundStation%&gt;; var dateTimeStr = &lt;%=datetimesStr%&gt;; var AUStr = &lt;%=auStr%&gt;; var spaceCraft = &lt;%=spacecraft%&gt;; var dateTimes = dateTimeStr.toString().split(','); var auIDs = AUStr.toString().split(','); var latitude = new Array((test.length / 2)); var longitude = new Array(latitude.length); var i = 0; var markerArray = new Array(); for (var j = 0; j &lt; (test.length - 1); j = j + 2) { latitude[i] = eval(test[j+1]); longitude[i] = eval(test[j]); var position = new google.maps.LatLng(latitude[i], longitude[i]); var marker = new google.maps.Marker({ map:map, position:position }); markerArray.push(marker); i++; } var sumLat = 0; var sumLong = 0; for (i = 0; i &lt; latitude.length; i++) { sumLat += latitude[i]; sumLong += longitude[i]; } var avgLat = sumLat / latitude.length; var avgLong = sumLong / longitude.length; center = new google.maps.LatLng(avgLat, avgLong); map.panTo(center); var circle; var contentStr = new Array(); for (i = 0; i &lt; markerArray.length; i++) { position = markerArray[i].getPosition(); var circOptions = { strokeColor:"#770000", strokeOpacity:0.1, fillColor:"#881111", fillOpacity:0.4, map:map, center:position, radius:2500000 }; circle = new google.maps.Circle(circOptions); marker = markerArray[i]; contentStr[i] = '&lt;div id="content"&gt;' + '&lt;b&gt;Spacecraft: &lt;/b&gt;' + spaceCraft.toString() + '&lt;br /&gt;' + '&lt;b&gt;Start Time (UTC): &lt;/b&gt;' + dateTimes[i].toString() + '&lt;br /&gt;' + '&lt;b&gt;Position: &lt;/b&gt;(' + latitude[i].toString() + ', ' + longitude[i].toString() + ')&lt;br /&gt;' + '&lt;b&gt;AU ID: &lt;/b&gt;' + auIDs[i] + '&lt;br /&gt;' + '&lt;b&gt;Downlink Station: &lt;/b&gt;' + groundstation.toString() + '&lt;br /&gt;' + '&lt;/div&gt;'; addListener(map, marker, contentStr[i]); } } } function addListener(map, marker, content) { var infowindow = new google.maps.InfoWindow({ content:content }); google.maps.event.addListener(marker, 'mouseover', function() { if (mostRecentInfo) mostRecentInfo.close(); mostRecentInfo = infowindow; infowindow.open(map, this); }); } </code></pre> <p></p> <p>etc.</p>

    1. COTry stepping through the code with a debugger. Go to youtube.com and search for 'using chrome to debug javascript.' Now you can step through your code line by line and see where it is failing.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
