The Atlas April CTP is available and has some nice features.
I suggest everybody who takes his ASP.NET seriously tries it out. I really think Microsoft does a great job integrating "AJAX" into ASP.NET with ATLAS.
At the ATLAS Documentation website you can find lots of documentation and if you want to see demo's visit:
Pageflakes I think it gives you a really good idea of what ATLAS is capable of
Alongside the ATLAS Framework there also is a library that is developed. The "Atlas" Control Toolkit are a number (13) of controls for Atlas.
This makes it even more easy to develop Ajax enabled webapps.
The "Atlas" Control Toolkit consists of:
- CascadingDropDown: Easily link drop downs, complete with asynchronous population and no postbacks!
- CollapsiblePanel: This extender allows panels on your page to collapse and expand with no code.
- ConfirmButton: This extender adds a confirm dialog to any Button, LinkButton, or ImageButton control.
- DragPanel: Makes any panel into an object that you can drag around the page.
- HoverMenu: Allows UI to pop up next to a control when the user hovers over it.
- PopupControl: This extender turns any panel into a popup.
- ReorderList: This control is a full-featured data-bound control that allows its elements to be reordered on the client via drag and drop.
- TextBoxWatermark: This extender adds "watermark" prompt text to TextBoxes on the page.
- ToggleButton: This extender turns an ASP.NET CheckBox into an image checkbox.
- AlwaysVisibleControl: Docks a panel to a corner of the browser window and keeps it visible even when the user scrolls.
- DropShadow: This extender attractive drop shadows to any control on the page.
- ModalPopup: Allows you to show styled modal UI without using HTML dialogs.
- RoundedCorners: Rounds the corners of any control for a clean, professional look!
