  1. Excellent resource, but could you provide me guidance on accessibility for asp.net controls. Most of the related to focus, as when a control post backs the focus is not retained.

    1. Hi Murali! Sorry, but I’m afraid I cannot. I do not know anything about ASP.NET controls. I didn’t even realize these still exist. 🙂

  2. Hi Marco!

    Great blog! I am working on an Android app for a company that is sincerely concerned with accessibility and we’ve been tasked with, at a minimum, meeting Section 508 standards but hopefully making the experience truly world class for individuals using assistive technology. While efforts have been made in the past, this is a renewed effort and I would like to meet or exceed expectations.

    I have come to realize that because I do not use the tools or require them, I really need to develop a better understanding and get exposure to those that not only use, but depend on these tools. I cannot reliably pretend or “fake” being that user.

    I am short on resources and would appreciate any help or direction you might be able to provide in terms of development guidelines and standards and/or training.

    1. Hello, I’d love to help. Let’s take this conversation via email if you don’t mind. Please write to me with an intro at ppatel at EZFire dot net.
