ASP.NET Podcast Show #83 - Writing a Custom AJAX Extender

Wallym — Mon, 15 Jan 2007 11:01:00 GMT

Here is a videocast Paul did that shows you how to create a custom Extender control using the Microsoft ASP.Net AJAX Extensions. This will be the first of a series of video casts on custom ASP.Net AJAX controls. The next one will deal with extender controls using the AJAX Control toolkit and contrast the different approaches. The next one may deal with ScriptControls and so on.

This videocast will create a very basic extender control from scratch but will leave you with enough of the basics to fashion your own complex custom extender controls. Enjoy.

"Beginning ASP.NET 2.0 AJAX" - Status Update

Wallym — Thu, 16 Nov 2006 18:13:00 GMT

I've been pretty much underground for the past few weeks. I've not blogged or podcasted for a while. I've put a lot of time into my chapters on our upcoming book: "Beginning ASP.NET 2.0 AJAX." I am glad to say that as of about 12:30 pm local time, I shipped off my first draft of the UpdatePanel chapter. This is the last chapter that I have to do for the printed book. I'll be working on some downloadable content, but that is relatively small and for later on.

UpdatePanel Data Transfer and the beginRequest and endRequest client side page life cycle events - Microsoft AJAX Library and ASP.NET 2.0 AJAX Extensions

Wallym — Thu, 02 Nov 2006 01:03:00 GMT

Cross posted from: http://morewally.com/cs/blogs/wallym/archive/2006/11/01/470.aspx

Is AJAX really AJAX? The answer, like many other things, is “It Depends.” The AJAX acronym states that the X is for XML. I can’t speak for all frameworks, but some frameworks use JSON (JavaScript Object Notation) for some amount of their data transfer.

The UpdatePanel is a little bit different. It doesn’t always use JSON. It uses a custom textual format. On the arguments of the EndRequest handler that I created, the Args.get_response().getResponseData() method returns the content that is sent from the server to the web browser when the updatepanel sends data down to the client. The format of the data seems to be: Size|ControlType|ControlName|ControlData. In this case, the size is 2775 bytes(I assume), the updatePanel is being acted on, the control that is acted upon is uplSearch, and then the data that is sent.

I hope that this is an interesting fact that has brightened your day. Note that this also shows how to use the beginRequest and endRequest client side page life cycle events.

Code I used:

<!--

Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(beginRequestHandle);

Sys.WebForms.PageRequestManager.getInstance().add_endRequest(endRequestHandle);

function beginRequestHandle(sender, Args)

{

alert("Begin Request Handle called.");

}

function endRequestHandle(sender, Args)

{

for(m in Args.get_response())

{

if((m.indexOf("get_") == 0)&&(m!="get_object"))

{

alert(m + ": " + eval("Args.get_response()." + m + "()"));

}

alert("End Request Handle called.");

}

-->

</script>

Data that was sent back:

Client side Page Lifecycle with the UpdatePanel - Microsoft AJAX Library and ASP.NET 2.0 AJAX Extensions

Wallym — Mon, 30 Oct 2006 03:49:00 GMT

The UpdatePanel and the asynchronous postback support a new client side side page lifecycle. I've been going through this over the past couple of days. Its pretty interesting stuff.

Getting data from a web service with Microsoft AJAX Library October Release using the Core bits - Microsoft AJAX Library and ASP.NET 2.0 AJAX Extensions

Wallym — Sun, 29 Oct 2006 13:32:00 GMT

I've been work with getting data back from a web service with the October Release and using the Core Bits. If I try and return a datatable, I have been getting an error. I did some checking and I found that the datatable serializer is in the CTP dll, so this has been a frustrating situation. I did some reading and some additional checking and it looks like the only way to return data from a web service through a web service is by creating a strongly typed set of objects. I've been creating a Generic List<T> and then calling a .ToArray() when I return the data. if you have some additional suggestions, feel free to add them as a comment in this message.
