Top Ajax Technologies and RIA Frameworks
I posted a fairly comprehensive list of RIA frameworks and Ajax technologies rated on:
- Completeness of their UI control set, based on the list of essential controls
- Usability of the controls
- Aesthetics, based on the default visual design
I also included some examples of applications built with the top frameworks and technologies:
Check out this excellent article by Janko: Ultimate guide to table UI patterns. It is full of great examples and suggestions.
After reading it, I just had to add three more scenarios:
1. Inline Editing
Quicken Online allows simple editing with a pull down for more advanced editing.
Mint.com does the same.
The Ajax framework Ext JS and Ext for GWT offers a pre-built Grid row editor component. Try out the demo. This would work well for tables that are primarily read-only but might need to be edited. This design is not for heavy data entry.
For heavy data entry, use a design like Harvest. They offer a simple grid layout that keeps a live total and provides a Save button for saving all the entries once the person is done (it also auto saves periodically).
Google Docs is an online spreadsheet application with inline editing. It also has a Save button for the whole spreadsheet, as opposed to per row updates.
Inline Editing Best Practices
- Implement tab navigation when you create a table with inline editing.
- Consider how to handle errors, such as highlighting rows or cells with errors in a way that is easy for a person to correct the issues. Don’t break the person’s data entry flow by locking them in a cell with an error, simply highlight the cell with the problem and provide a way for them to return to it later to fix it.
- Offer undo and redo functionality.
Swivel is an app that acts a lot like Excel and provides cell specific error messages.
2. Super Wide Tables
I received an email last week asking me about super wide tables. The email said “I’ve come to the conclusion that breaking them up into smaller chunks is maybe the best way to go, rather than going with a horizontal scroll-bar that goes on for days.”
Based on a lot of design work Bill Scott and I did for the airline industry, I would instead propose instead applying these principles:
- Organize the most important columns to the left.
- Experiment with frozen/fixed columns, so if the person does need to horizontally scroll, they can keep context.
- Only show a set number of columns in the default view (so there is no horizontal scrolling in the default view) and offer a Customize option so the person can choose to hide or show more columns. ExtJs has this built into the column dropdown; I usually add a customize button to the table toolbar with Hide/Show column functionality.
- Offer resizing of columns.
- Offer rearranging of columns.
- If you have a table with some columns editable and other read-only, group editable with editable, read-only with read only.
- Don’t abbreviate column titles, reduce spacing or padding, or drop to a smaller font to fit your table on the screen. That won’t help anyone use your app.
- Try out fat rows like this example from Survs. Instead of having a column for title, created by, created on, last updated on, all of that information is in the second column. Good visual design can help organize the information in a more meaningful way which makes your data easier to scan.
- Use a summary row to chunk the data if appropriate. I know this won’t make your table any narrower, but it might make it more readable.
- Consider putting a visual summary, or roll-up, above the table so the person can make sense of the data visually before diving into a huge table of numbers.
Discover Spend Analyzer offer a dual purpose summary and filter above the rows of transaions. Play with the demo to try it out.
3. In-column Filtering
The example included in Janko’s article has dynamic filters above the table (dynamic meaning, when you make a selection, it dynamically updates the table content- without an extra submit action).
In some web applications, like heavy productivity applications or enterprise apps, in-column filtering is a powerful option to offer. It is pretty easy to implement with Flex or Ajax. Just validate the need for this type of functionality with your customers; it could be overkill for people who just need simple filtering.
Example from Zenoss Open Source Server and Network Monitoring
Try this at Telerik RadControls. This example requires a click on the filter button in the column, and has the option for selecting a specific way to apply the filter.
Play with SmartClientRIA, where the implementation ( they blank out the whole content area while filtering) makes it seem slow.
And a Flex example, where clicking on the filter icon lets you search in that specific column, and then you can further refine by filtering other columns.
Here’s my talk from Dec 11 at the Adobe Austin Users Group. This is a beginners introduction to designing for Flex, although there are some goodies for experienced designers too.
If you are looking to stock your library, you can’t go wrong with this list of books. These are the books that are literally on my desk, listed in order from top of the stack to the bottom.

If you are a fan of Edward Tufte, you need this book. If you don’t know who Tufte is, you need this book, and all of Tufte’s books. It is chock full of ideas for visualizing data in more meaningful ways. This is on the top of the stack because I just got it- it is quite lovely.
By Todd Warfel. Rosenfeld Media, November 2009.
These concepts completely changed the way we do business. Full of real examples of how to use different popular tools for prototyping. this is # 2 in my stack because I had to look up some information about prototyping with Fireworks this morning.
The book is available exclusively from Smashing Magazine. This book looks at Web design rules of thumb, color theory, usability guidelines, user interface design, best coding and optimization practices, as well as typography, marketing, branding and exclusive insights from top designers across the globe. Oh, and one of my applications, OtherInbox, is in the first chapter!
By Bill Scott and Theresa Neil. O’Reilly Media, January 2009.
Yeah, I know this is our book, but it really is on my desk. I use it for reference at least once a week. I had to look up ZUIs, zoomable user interfaces, earlier this week for a project.
By Joshua Porter. New Riders 2008.
Great, great read. Worth every penny because it is full of practical advice. Make sure you also look at Joshua’s talk on SlideShare: Designing for Social Interaction. I don’t necessarily refer to this book every day, but I recommend it to at least five start-ups a week.
By Christian Crumlish, Erin Malone. O’Reilly Media, September 2009.
“This book is a fairly exhaustive catalog of most UI patterns in place today with sites that integrate social networking. There are some very interesting discussions about each pattern, when to use it and who uses it. ” from an Amazon review. I need to pull this book out of the stack and take it with me on the plane next week.
By Luke Wroblewski. Rosenfeld Media, May 2008.
Anyone who designs anything for the web needs a copy of this. It makes it so nice to not have to think about designing forms. I can spend my time on more interesting design challenges. This book doesn’t leave my desk.
by Matthew Linderman and Jason Fried
Let the 37signals team show you the best way to prevent your customers from making mistakes, and help them recover for errors if a mistake does occur. This book doesn’t leave my desk either.
By Alan Cooper. Wiley 2007.
Learn the rules before you break them. Please. Pretty please with a cherry on top? Get this book and read it if you are responsible for designing anything more than a simple web site. Good for Flex developers and Ajax developers as well. Lots of patterns that can be extrapolated for Rich Internet Applications.
Check out Design GalleRIA– A design gallery and showcase of the best Rich Internet Applications. I add a couple of new ones each week. Please comment with your favorite RIAs (Ajax, Flex, Silverlight, Laszlo…). My goal is 100+ by the end of 2009!
New featured article on InsideRIA, 50 Most Usable RIAs.
Bill and I have reviewed hundreds of rich Internet applications, RIAs, while compiling examples for our book and subsequent presentations and articles.
We recently realized that we had amassed quite a list of applications. Thinking other designers and developers might be interested in these resources, we applied two simple criteria to identify the top fifty:
Number 1: Does it adhere to the 10 basic usability principles?
Number 2: Is it really rich? Developing a product with Ajax, Flex, or Silverlight doesn’t inherently make it rich. A usable RIA will embody these six principles: Make it Direct, Keep it Lightweight, Stay on the Page, Provide Invitations, Use Transitions, React Immediately. For more detailed descriptions of each principle, see the Explore the Book section of this site.
10 of the 50
I had an opportunity to speak about my favorite topic: design patterns and principles for rich applications. The talk is titled Designing Rich Applications– and illustrates the need for richness at four levels:
- application structure
- screen layout
- selecting rich UI controls
I’m working on a nifty little flip book that has all of the application patterns, screen patterns, rich UI controls and interaction patterns. All the patterns are on index cards and you can carry it into design sessions- and flip through it for inspiration- or to find a certain pattern.
Let me know if you think this would be useful.
