Async loading with Non-blocking UI in ASP.NET with Gaia Ajax

by Jan Blomquist 18. January 2010 14:40

 

We've just published a new sample that demonstrates how to create a web page that loads items as they become available and doesn't block the UI. That means you can fully use the Web Application while another thread is spinning on the server doing the hard work.

Or you can pickup a nightly drop here:

The idea behind this is not new, but Gaia Ajax makes this so simple to implement and so fast thanks to the automatic diff/merge capabilities of the DRIMR technology which was introduced in Gaia Ajax 3.6. Click here to view a view about Gaia Ajax DRIMR
Sometimes Web Applications are dropped in favor of traditional Desktop applications because of performance requirements. It's not viable to create web applications that requires long time before responding. However, many functions still require lots of processsing before they can return data at all. The ideal way to solve this is the following

  1. Serve up the UI instantly.
  2. Allow the user to start the time consuming task
  3. Deliver the data for consumption in the UI as it becomes available -leaving the application operational. 

Creating the UI for this kind of application is hard enough as it requires you to dig into multi-threading and it's many pitfalls. Creating the UI as a Web Application becomes almost unthinkable as it adds yet another layer of complexity that makes the project run the risk of blowing up. That being said, any sane person reverts to the good old locally installed application with it's drawbacks to solve the problem.

Does it really have to be like that? I will argue in this blog that it's just as easy -or easier? to create a scalable, robust, multi-threaded web application in ASP.NET that doesn't block the UI -than to revert to writing desktop applications.

The reason is partially because ASP.NET is multi-threaded in itself. Each web request is tied to a Worker thread that lives throughout the duration of that page lifecycle. The process of running the lifecycle and generating the control tree is very in-expensive. In Gaia Ajax, the lifecycle running time is even chopped an additional 30%. Almost always the most expensive operation is your I/O threads. These threads often deal with files, databases, webservices and anything else which is not (in-process). I/O is so dramatically more expensive (realtive to worker threads) that Microsoft introduced the Async pattern in ASP.NET 2.0

"The problem with the ASYNC pattern is still that no WebPage is being delivered before all I/O threads are finished with their work". I argue that another option is to serve the WebPage with few or no I/O threads at all. The delivery time of the web application becomes instant.

Does that make any sense?
These I/O calls where there for a reason wheren't they? -Yes, and I am not saying that they are not going to be executed. I am simply saying that you can deliver the results over ajax by using a diff/merge strategy. In Gaia Ajax 3.6 you get automatic diff/merge for free! :-) Also the A in Ajax stands for asynchronous so they don't block the UI either.

But isn't multithreading Evil?
Yes it's evil and if you can avoid it -so you should. However, in .NET we've gotten lots of tools, code, patterns and various ways of dealing with the issue of concurrency. Modern CPU's are not scaling in terms of higher clock speed, but more cores (Link to Intel 48 cores). The LINQ to Parallells project  is now going shipped as part of .NET Framework 4.0. Instead of being afraid of the beast, I think it's time we deal with it and create the next generation of modern web applications utilizing all these cores available to us.

Ok, so how does this relate to Gaia Ajax?
Gaia makes this paradigm easy to implement with no javascript, no bloat and only the state changes are merged down to the client. Also Gaia implements an ajax request queue which only dispatches 1 ajax request at a time allowing for no concurrency issues there. You still have to deal with concurrency, race conditions, etc in your web application, but like I said that's a lot easier with all the stuff that's available to us there.

The following code snippets outline how this simple example was written. It contains 1 aspx file with a button, datagrid and timer and in the codebehind we toggle enabled and visibility properties and kick off the work which goes on in the BackgroundWorkerTask.cs file. The sample was written to be minimalistic and simple and serves more as a proof-of-concept than production ready code. The code is available in the sample too, but I'll paste it in here for your convenience.

Gaia Ajax 3.6 Final Release

by Jan Blomquist 24. November 2009 12:37

 

After some thousand hours of both eurekas and hard work, the "safe-to-put-in-production" bits of Gaia Ajax 3.6 is finally ready to be routed through your NIC and assembled on your harddrive. In this blog I will tell you the 3W+1H: Why, What, How & Where.

Why?

Ideally the product should speak for itself, but endow me a few bytes of your browser memory to unravel the architectural spirit behind the product. Gaia was built with the following ideas in mind:

  • Simplicity
  • Code reuse in a managed language of choice
  • Focus on highly reusable & versatile building blocks
  • It was designed to be your favorite toolbox which just works across all your web projects

"Philosophically speaking it's not so much about the controls that you find there, but more about the controls which you don't find".

This abstract idea can be a little difficult to comprehend at first, but you will become a better developer once you really get it. We humans find it hard to visualize on the non-existent, the history that never took place. A lot of one-size-fits-all components sometimes solves too much (often you need < 1%). Your job title quickly gets deduced to Professional Property Configurator and your products end up looking like everything else (we know! because we see it all the time) and where is the differentiator in that? Don't get me wrong -sometimes these are desireable means to an admirable goal, just don't forget the old gipsy curse: "May you get what you want and want what you get".

What do you get with Gaia Ajax 3.6?

3.6 contains an abundance of new "stuff". In reality, too much to cover here -so permittez-moi to show you what we believe are the most important updates for you.

DRIMR (Did you say D-R-I-M-R?)

DRIMR is an acronym for Dynamic Removals, Inserts, Moves and Replacements. DRIMR conceals all ajax complexity, shields the developer from exposure to low level details and is a common characteristic shared by all Gaia controls. It converges the Ajax umbrella into a beautiful and optimized solution for ASP.NET. In many of our demanding samples, No Re-Rendering takes place at all, except the initial load. This means:
  1. You can move a control between Control Collections and we'll just move the control in the Browser too :-)
  2. You can remove a control and replace it with a new control and if they are of the same type we will reuse that instance in the Browser and only emit the state changes. A great example is paging/sorting in the GridView: Only the Text property of the Labels get's serialized.
  3. You can remove a control entirely and we'll just issue a RemoveControlCommand to the Browser, not touching anything else.
  4. It also means a lot more to you, but we'll just have to expand information on this topic as we go.
DRIMR is such a powerful concept that you might not truly believe or understand what I am saying here, so I encourage you to check out for yourself. We hope DRIMR will inspire a whole new breed of web applications written purely in managed code that doesn't utilize unnecessary re-rendering strategies at all and we depend on you to create these masterpieces. The alternative route being a spaghetti of technologies blended together in a grey mass, colorless and with no distinguishable beauty. And you know how we feel about that now?

Interestingly DRIMR represents only a tiny fraction (1/107) of the tracker items that were solved for the 3.6 release. Imagine how many new features the 3.6 release contains? Other single items include: (>120++) New Samples, GridView, ImageMap, New Effect API, Validation Controls and numerous other features/enhancements.


120++ Samples

Lightbox and Carousel SampleOur brand new samples framework was written from scratch and each sample is now broken into a neatly organized folder structure. Many of the samples were written with extensibility in mind and should be easily customizable and integrated in your own appz. You also get a local copy of the samples when you install Gaia Ajax. Alternatively you can browse our samples online which we hopefully have mirrored somewhere near you:
Ajax GridView

Ajax GridView (for ASP.NET "Ninja" developers)

GridView is the prodigy of our DRIMR technology featuring

  • Dynamic inserts of rows/columns
  • Automatic removals,
  • Sorting and paging
  • + All other features available in the ASP.NET GridView (because it IS the ASP.NET GridView).

Example: If you select a row, Gaia detects that only a CssClass change took place, so that's the only thing Gaia "wires over". This in turn delivers a GridView with an amazing performance that you can use out of the box or upgrade your existing ASP.NET GridView. Instantly turn rows into edit mode, insert ANY control and get JSON-like serialization of data through familiar DataBind() operations in the codebehind. You can use WebServices if you want, but you don't have to, any collection will do just fine.

A potpourri of other interesting features

To economize on your precious time, allow me to just list up some additional things we hope you will enjoy in this release:
  1. New class based Effect API which allows
    1. Run multiple effects in parallel
    2. Run multiple effects in a queue
    3. Client side only effects
    4. Attaching to special control events (ie. Appear/Close)
    5. Lots of usage options
  2. Full IE6 support
    1. Css compatible
    2. Modal windows
    3. Samples Website 100% written for IE6
  3. Brand new controls
    1. ImageMap
    2. ValidatorControls
    3. BrowserHistory
    4. GridView
  4. Gaia Ajax 3.6 contains a total of 41 Server Controls. That's less than $5 pr/control! Let us know if you can write them cheaper, because then -You are hired! 
  5. AspectBinding to Events, Properties and methods. This means more native events are exposed on controls directly and the Modal property is back on Window. The TextBox for example now has:
    1. OnMouseOver
    2. OnMouseOut
    3. OnBlur
    4. OnFocus
    5. OnDoubleClick
    6. OnSelect
    7. + The rest which you already know
  6. Amazing new Drag&Drop capabilities. Dragging can now occur at the document level, circumventing stacking contexts, overflows and other obstacles when items are being dragged around. It also supports
    1. Ghosting
    2. Shallow Copies
    3. Custom CssClasses during Drag&Drop
  7. General Performance optimizations and JavaScript refactorings.
  8. The Nested Windows sample demonstrates how you can make the impossible possible with Gaia Ajax. In this sample we can add "unlimited" levels of modality recursively to nested Windows with roughly 20 lines of C# code!
  9. I've said it before and I'll say it again. Par example: the chess game does not perform re-rendering at all. All pieces are "physically" moved in the browser, captured pieces are replaced and non-valid moves slides the control back where it came from, and the best part: It's all written in 100% pure .NET managed code on the server. No Biz Exposed!

Here's a snippet of the server response during a piece capture:
   1:  Gaia.CRP('f7_black-pawn-f7','f3_white-queen-f3',1);
   2:  $G('f3_white-queen-3')
   3:  .setImageUrl('img/white_queen.png')
   4:  .setID('f7_white-queen-f7');

If you are still in doubt? Check out yourself and unleash the developer animal inside you! I don't have the stamina to continue this list so let me just quote one of our recent customers here: "Gaia is the best investment we've done in a LONG time!" -ConnectIT, Norway

How?

The 3.6 codename has been "fairytale" and was partially inspired by the MGP winner Alexander Rybak's song with the same name. We decided on that name just two months before the MGP final in Moscow due to a gut feeling that Alex would bring medals and honor home to Norway. I think Gemini reveals the publish date :-)

Development of Gaia Ajax is inspired from a mix of agile/bazaar techniques. Core development is mostly in-house, but external contributers are welcome to participate in the open forums/wiki/etc. Today many such contributions exist, including a full Outlook-like Scheduler written by Pavol. For a list of all extensions go here. The project enjoys a tight customer/community feedback loop with an instant report-confirm-fix-test-build-publish loop with our fully automated build system.

Other characteristics of the project include a high degree of transparency & Public Access to:

Compatibility

We've focused on backwards compatibility and for most cases you can do a binary upgrade by just replacing the dlls. ForceAnUpdate() is still hanging around, but should be safe in most scenarios to remove where Gaia only controls are in use. Doing so will result in vast speed improvements and reduced payload for ajax callbacks. for both the client and server, whereas DRIMR does not!

Note: Upgrade fails if you're doing a full custom implementation of IAjaxControl. However, inheriting directly from Gaia controls is considered safe.

Retracted Feature(s)

The alpha/beta release contained a selection of four new skins. These skins did not qualify our QA phase and unfortunately was removed. The skins are available in the SVN repositories under /gaia-ajax-skins/branches/ and they might be released in the future when quality is improved. However, we have plans to release more skins in the near future and these will be made available as a free add-on to the 3.6 release or in a future service pack to 3.6. We'll come back with more information regarding this in a few weeks.

Where?

Where to go from here? Well, that depends a great deal on where you are heading? If you are totally sold at this point (we certainly hope so), just pickup the SKU most suitable for you here: 

The installer is digitally signed (verifies authority) and integrates nicely with VS.NET 2005 & 2008 and you get a shortcut to a locally installed copy of the samples on your start menu. Opening the Samples in VS allows you to dissect the code and see for yourself how quickly you can build similar high quality code effortlessly.

Then I would suggest the following reading:
Here are a few selected samples which demonstrates some of the unique features of Gaia Ajax:

Conclusion

We hope you are going to love Gaia Ajax as much as we do. Also keep in mind that we truly want you to be successful with Gaia and that we are there for you when you need us. Don't hesitate to use email, forums, twitter, phone or any other surface we are exposed through.

Time's up! Gaia Ajax 3.6 Alpha Released!

by Jan Blomquist 13. September 2009 21:01

Thank you for your patience and continued belief in our product. It is our vision to bring you the finest quality for ajax development on the ASP.NET platform. The 3.6 version comes with practical innovation previously unavailable to ASP.NET developers. Hopefully it will bring "goosebumps" similar to the ones we had the first time Microsoft unveiled ASP.NET almost a decade ago. 

"3.6 is backwards compatible and introduces a paradigm shift called adaptive rendering"

Highlights from the Gaia Ajax 3.6 release

1. Adaptive Rendering
Adaptive Rendering is a mind-blowing concept that enables dynamic insertion, removal, moving and replacement of individual controls. The concept has far reaching implications and is the breakthrough technology that will make you hunger for Gaia as the building blocks for your UI layer

  • Click here for a sample that demonstrates dynamic inserts and removals of controls and compare it to the usage of traditional partial rendering
  • Click here for a sample of the chess game featuring dynamic control moves
  • Click here for a sample of our "PageFlakes" sample that also features dynamic moves
  • Click here to check out a sample that demonstrates all features of adaptive rendering, including control replacements via databinding
Jan Blomquist has written an extensive review of Adaptive Rendering on his personal blog.

2. Ajax GridView
The Gaia Ajax GridView is a premier example of adaptive rendering as it enables the worlds most advanced GridView for ASP.NET without much code at all. The GridView still supports all the operations like ( filtering, sorting, selection, deletions, updates, etc ) and it's all ajaxified thanks to adaptive rendering.  

  • Click here for a sample that demonstrates the Gaia Ajax GridView in action

3. 100++ new Samples!
In the package you will find a total of 128 samples ranging from minimalistic ones to extensive, almost full applications in themselves. This is all packaged into a new samples framework that simplifies navigation, code view, VB.NET code availability, etc. 

Note: The samples are now utilizing the WAP project type

Gaia Ajax training - two new courses in Oslo, Norway (Early Bird Extended to 20th of September)

by Stian Solberg 3. September 2009 09:00

Gaia Ajax is a powerful web platform for both complex enterprise applications and fast-up-and-running web sites. In many ways Gaia Ajax completes what many developers are missing on the ASP.NET platform both in regards to how easy it should be to create a rich and responsive web experience, but also how to unleash the highest productivity in your daily development. Our customers say they increase their productivity by 30-60% when developing with Gaia compared to other approaches towards web development.

We're happy to announce two brand new courses this year. Based on the feedback we have received, we have split the courses into two different levels: Introduction to Gaia Ajax and Advanced Ajax development with Gaia Ajax. Each course goes over two days.

What's coming in Gaia Ajax 3.6?

We have been working on 3.6 for a while already. It will be a great new step in the Gaia experience, making it even easier and more fun to create the next generation web applications. Here's what we're adding:

  • Aspect Binding
    Now you can add behaviours and events declarative to the Gaia controls. Want to set your Gaia Window modal? Just add the property Modal="True" and it is done! Subscribe to events like OnClick, OnDoubleClick, OnBlur, OnFocused, OnMouseOver, OnMouseOut, OnSelect ++ and your ASP.NET web application will never be the same.
  • New Gaia Effect library
    Faster and more effect options to choose from. Enjoy parallel and queued effects.
  • New Gaia History control
    Make friends with the browser navigation in your Ajax app.
  • New skins coming
    Office, IGaia, Portal and Social
  • New and richer GMap control
    We have spent some time on our Google Maps integration. Zoom, catch click events, add InfoWindows and pan to new coordinates. Finally Google Maps is for everyone!
  • New Gaia Ajax ImageMap control
    Just like the ASP.NET ImageMap control.
  • Advanced keyboard mapping
    Add keyboard integration to your web application. Another reason to go from desktop to web...
  • More features and events to Calendar and DateTimePicker
    We have added properties like FirstDayOfWeek and VisibleDate, and events like  OnCalendarDayClicking and OnDayRender
  • Core: Smaller JavaScript footprint
    In the work with revamping the Gaia Effects, we have moved script.aculo.us out of the core.
Want to test early? Take a look at the code? Get the source code, test a nightly build
Have a nice summer!
Best regards

How To Create An Async Ajax Google Search with ASP.NET And Gaia Ajax

by Stian Solberg 26. May 2009 06:30

Recently we decided to add a searching feature for the different sites we run on gaiaware.net: main site, blogs, forum, tracker, docs and API reference. We wanted to be able to search each site separately and still have all the results presented in a intuitive way. And of course, it should be built using Gaia Ajax, so it could be quickly developed (our customers say they increase the productivity by 30-50% on the ASP.NET platform when using Gaia Ajax) and give a responsive and ajaxified user experience.

Async Search with ASP.NET Ajax

We have purchased a Google Site Search subscription so we don't have to reinvent the wheel again and make our own site spider. The Google Site Search gives us the search results in XML, and we can parse and present them in any way we would like.

The challenge: multiple search sources with ASP.NET

Since we wanted to present the results from each sub site in separate sections, we needed to overcome some limitations of what Google Site Search gives us. E.g. you can return max 20 results per search. Since we wanted to separate the results in each sub domain (e.g. forum.gaiaware.net) we needed to use the useful "site:" parameter in a Google query. That meant that we needed to fire off 5-6 Google searches for each search we executed on our own page. Our immediate concern was how long time it would take to perform so many Google searches, return them, parse them and present them on our ASP.NET page.
