30 Essential Controls
February 4, 2009
This is the second article in a three part series on patterns and principles for RIA design.
- Standard Screen Patterns: 12 patterns w/100 examples
- Essential Controls: 30 controls for RIA design and development
- Components for Commonly Requested Features: 15 patterns and examples
Every designer has a set of controls they rely on to communicate an effective UI. This is my library of essential controls.

Unfortunately, no single RIA framework offers all 30 of these. So I included a checklist of which frameworks provide each control. If you have an addition or correction, please e-mail me, and I will post an updated framework/control matrix.

Very nice work, im starting on Flex and this is very useful. I need to know how to get all this components in one way. If you have them, can you help me sending me a link of a tutorial or some to use them?
Thanks! and good work!

or that you put in containers category ?

We are very excited about SproutCore and would like to build a complex web application using SproutCore. Our goal is to build an advanced “Thick” client browser based product to deliver a “desktop-like” User experience. Can you recommend a strong development group who has experience with SproutCore to help us create it or could you recommend someone to act as a consultant to help us select the right offshore development team and define the requirements correctly?

For #22, I’ve been trying to find a toolkit that has the dual sliders for specifying a range. All the ones I’ve found are single sliders. Can you point me to a dual slider version like innography?
April 22, 2009 at 10:52 pm
B.Z.- JQuery has a dual slider:

thanks for sharing all these examples. a great resource you have here.
April 24, 2009 at 5:48 pm
@theresaneil,
Thanks for that link… the jQuery control is definitely a dual slider. The slider I’m looking for needs to also allow you to click and drag from the middle. So let’s say you set the range from 50 to 150, you could slide it up from the middle and it would move both ends, say up to 70 to 170 simultaneously.
