Simply, add a sleep statement to your page_load event (Thread.Sleep(3000);) and run your page.  If you are using IE7 like I am, on the post back (for a full page), you will see the windows icon spinning in the tab control.  If you see that, you are getting a full page post back. If not, chances are you are not.

Hope this helps!

 function pageLoad() {

        req = new ActiveXObject("Msxml2.XMLHTTP");

        if (req) {

            req.onreadystatechange = processStateChange;

            req.open("GET", "AttendeeZipCode.ashx", true);

            req.send();

        }

    }

    function processStateChange() {

        statusDiv = document.getElementById("stats");

        if (req.readyState == 0) { statusDiv.innerHTML = "UNINITIALIZED"; }

        if (req.readyState == 1) { statusDiv.innerHTML = "LOADING"; }

        if (req.readyState == 2) { statusDiv.innerHTML = "LOADED"; }

        if (req.readyState == 3) { statusDiv.innerHTML = "INTERACTIVE"; }

        if (req.readyState == 4) {

            //statusDiv.innerHTML = "COMPLETE";

            GetMap();

            //statusDiv.innerHTML = req.responseText;

            var dataObject = json_parse(req.responseText);

            CreateLayerAttendees();

            CreateLayerSpeakers();

            var points = new Array();

            for (var i = 0; i < dataObject.length; i++) {

                var lattitude = dataObject[i].lattitude;

                var longitude = dataObject[i].longitude;

                points[i] = new VELatLong(lattitude, longitude);

                if (dataObject[i].isSpeaker) {

                    AddOnePin(layerSpeaker, lattitude, longitude, "x", "x", true);

                }

                else {

                    AddOnePin(layerAttendee, lattitude, longitude, "x", "x", false);

                }

                AddOnePin(layerAttendee, lattitude, longitude, "x", "x",dataObject[i].isSpeaker);

            }

            map.SetMapView(points);

        }

    }

Well, that worked great until I ran it on Firefox and Chrome.  Basically, nothing happened.  So, off to my smart friends at the local Java Users Group and they suggested I should use a JavaScript library because my solution only works for IE.  With that hint, I grabbed my favorite AJAX book by Alessandro Gallo, Ajax in Action and started reading.  Turns out, there is indeed a Microsoft Ajax Library solution to this and here it is.

 function pageLoad() {

            var request = new Sys.Net.WebRequest();

            request.set_url("AttendeeZipCode.ashx");

            request.add_completed(onRequestCompleted);

            request.invoke();

        }

        function onRequestCompleted(executor, args) {

            processResults(executor.get_responseData());

        }

Now, Firefox, Chrome, and IE all work!  and, look what a nice result we get.

Hope this helps!

Article Series

So, first, a little background.  As many of you know, I’ve been the ring leader of Silicon Valley Code Camp here in northern California for the past 2 years.  Since Code Camp is a limited budget, 100% volunteer effort, the most important thing is to have efficient communications between everyone.  Attendees, Speakers, Organizer, Sponsors and everyone else involved in the event.  To that end, the first code camp web site was created.  It was based on CSS provided by Microsoft.  Check out the post I made two years ago about it titled "Zero to Professional Web Site in Two Days".

This year, we are planning on a different format.  I don’t want to give too much away because we have not formally announced the changes, but if you look carefully at the designs, you might get an idea what these changes are going to be.  I’m getting slightly off topic.  The purpose of this series of articles to take you with me, step by step through building the web site.  This time,
we are going to do it right.  Professional Designer (volunteer) and Professional CSS Implementer (not me, but we do have some budget for this from last year).

So, here are the steps.

1. Decide on what changes need to be made
2. Work with a professional designer to make mock ups (photoshop, fireworks, etc.)
3. Create css and html pages from the designers work
4. Implement the css and html in asp.net
5. Test
6. Publish

So far, we have done steps 1,2 and are working on step 3.  I’ve alluded to the requirements above, but don’t want to spoil too many surprises.  Suffice to say, that is done already.  Step 2 is also now complete.  The professional designer gave us very detailed PSD files that we can turn over to a css wizard.  First, let me show you some of the designs and peek into fireworks to see what is actually under the covers.

First, here are some screen shots of what pages will look like (png files created from the PSD files)

Include is also a PDF file.  It allows the person doing the css and html to really do a good job of pulling the pieces apart to make great web content.

(notice the detailed names for all the layers!  this kind of consistency makes it much easier to implement in html and css).

Step 3 is to hand this over to a designer.  I did not have someone to use locally, so I decided to take a shot at using rentacoder.  I posted a detailed specification which you can see on that site if you navigate to this url: 
http://www.rentacoder.com./RentACoder/misc/BidRequests/ShowBidRequest.asp?lngBidRequestId=924960 

Notice the detailed specifications as well as the 13 bids that have been made ranging from $100 to $1000.  I posted a question on the forums asking if anyone had used any of these services and the response was yes, but don’t take the lowest bid and also make sure you use someone with lots of experience.  I haven’t decided next steps yet (that is who to choose), but I will keep posting as I build this web site.

Stay tuned!

I enthusiastically recommend it to anyone trying to incorporate Ajax into their asp.net applications.  It’s not only got a great introduction, but also goes into lots of useful details for day to day programming.

So, now, where to use it?  Code Camp of course!  Now, if you browse to the Sessions listing, you’ll see the DevExpress Cloud Control in use.

You can see this control in action at our web site here: 

http://www.siliconvalley-codecamp.com/Sessions.aspx

My experience with using this control was great!  Easy to setup.  Below is all the code I needed on my asp page to make it happen.
