Atlas is about Javascript OOP, AJAX, it offers client and server controls, cross-browser compatibility, UI enhancements, it supports flexible binding and a declarative programming style. Atlas integrates the ASP.NET server technology and allows to develop web applications. At the moment, Atlas...

Let's begin with the classic ‘Hello World!’ example. The HelloWorld.aspx page has one button. When the button is clicked, data is retrieved from the server and displayed in an alert box. One of the core features of Atlas is getting data form web server by asynchronous calls. In this...

The recent release of Atlas introduces the concept of ExtenderControls . Extenders are server controls that allow extending a set of ASP.NET server controls by adding client side functionality. Basically, an ExtenderControl gives a better design time experience by allowing to treat...

I've just posted some topics about Atlas but seems no banner ads are shown in the post. I wonder if people do not like ASP.NET? Or something else? I've checked the keywords of page http://dflying.dflying.net/1/archive/72_extending_the_autocompleteextender_in_atlas.html at...

The Atlas framework provides amazing cross-browser support for drag & drop operations. Basically, to create a UI with drag & drop is really simple and we just need: Draggable items and Drop targets . Draggable items are DOM elements that can be moved around...

Atlas provides Web.Data.DataTable control which is just like the behavior of ADO.NET DataTable object and the Atlas Framework can also make the conversion between the two types for you automatically. Here are some common operations on Atlas DataTable. Get DataTable from server Server side...

Currently the Tag Cloud Plug-in of LifeType uses search to fetch related topics and just shows the raw URL such as http://dflying.dflying.net/index.php?searchTerms=ajax&op=Search&blogId=1 which may not friendly enough to search engines. I’ve added a line in .htaccess file # Search (i.e....

UpdatePanel is so important an Atlas control that connects the traditional ASP.NET application and the new Web 2.0 AJAX implementation. That is, if you own applications wrote by ASP.NET, you do not need to take many changes to get it runs as the cool AJAX way by using UpdatePanel. Or, if you are...

That will be very cool and useful if you can show your user a ProgressBar on a web page which displays the actual progress of some long operations. Now let’s try to make it possible by using ASP.NET Atlas. This post can also show you some basic conceptions about extending Atlas client side...

The first Atlas control a developer may use should be the UpdatePanel, which is really powerful and easy to use. It provides us a closer view of Atlas. I’ve posted a simple introduction ( http://dflying.dflying.net/1/archive/96_introduction_to_atlas_updatepanel.html ) to UpdatePanel here and...

There are two ways to expose a server side method to the client side Atlas controls, Web Service and Page Method. The one I prefer is the Web Service way. The important thing everyone should keep in mind is that the Page Method calls and Web Service calls work very differently from each other....

Atlas provides a binding model which is much more powerful than the data-binding model in ASP.NET. It is quite a flexible binding mechanism; just something like the binding models in WPF (Windows Presentation Foundation).Atlas binding lets you bind any property of one component to any property...

Binding in ASP.NET Altas is really a powerful way to connect two objects (You may find more info about binding here: http://dflying.dflying.net/1/archive/109_atlas_unleashed-bindings.html ). Atlas will automatically apply the changes of the property in source object to the target object if you...

Validators are a powerful way of checking the data entered by the user into ASP.NET Atlas client side controls of type InputControl, such as the Web.UI.TextBox control. If you are familiar with ASP.NET, you must know the validators provided by ASP.NET as server controls. Atlas validators provide...

Introduction It is much more challenging to write Atlas code than C# code, for there’s no compile time check or IntelliSence in coding, and you have to trace the traffic between the client and server in runtime. Still there’s no powerful IDE/debugger for JavaScript. I’ve been working on...

Behaviors in Atlas are used to define what a control will behave when an event got fired. Behaviors encapsulate actions that can be associated with DHTML events, such as the click or hover events. They can also be a kind of components that can be attached to the client control to provide...

Components derived from the Action class in Atlas are used to specify the code to execute in response to events, which is similar to the event handlers. Action components enable you to declaratively bind actions to client events for common tasks such as calling methods, setting properties, and...

Since there are no introductions or official documents about the Atlas controls in namespace Sys.Data, and data accessing is so important a part is current web applications, I decided to share some of my ideas and experiences on this part of Atlas by a series of posts. Hope may help. Please...

In this post we are going to touch the key client side data components of Atlas – the DataTable, which is used to represent a tabular data structure. The DataTable object connects the actual data – the DataSource and the UI control – the ListView. It is the data field of a DataSource object, and...

This is the third, also the last part of introductions to Sys.Data controls. In my previous posts, we know how to get data from server side and store in client side by using DataSource controls and how to modify the data we get on client side by using DataTable object. We can display the data...
