Why Accessibility?
- In the 2000 U.S. census, nearly 20 of the
population reported a disability of some type.
Yes, 20. That is 1 in 5 people. Though a large
portion of this 20 may be attributed to age
related processes, the implications are
enormous. - http//www.webaim.org/

Our Assignment
- In 2003/04, with the help of staff
interns/application developers, we reviewed and
fixed a majority of our approximately 500
asp/asp.net Webpages - We had to work through various issues, especially
with the more complex data tables and asp.net
controls. - Further our use of standards-based coding
(Cascading Style Sheets)

Example Application MSIP Report Writer
- System used for staff to conduct on-site Missouri
School Improvement Program Reviews - What did we do?
- Added Skip Navigation
- Removed all font tags and controlled with style
sheet (CSS) - Added labels for each field and used hidden
labels for more complicated tables - Checked alternative text on images

ASP .Net
- Cannot attach a for property to
control - and are not the same
- idlblSchoolNoName runat"server"
- runat"server" autopostback"True
10
ASP .Net - Repeater Controls (unbound)
- Repeater controls can be a bit more difficult
since they dynamically create their id at
runtime. - Search
Text - vb code behind file
- Protected WithEvents txtBox As HtmlInputControl
11
ASP .Net - Repeater Controls (bound)
- vb.net code behind file
- Protected WithEvents rpt As Repeater
- Private Sub rpt_DataBind(ByVal s As Object,
ByVal e As repeaterItemEventArgs) Handles
rpt.ItemDataBound - Dim objItemType As ListItemType
CType(e.Item.ItemType, ListItemType) - If objItemType ListItemType.Item Or
objItemType ListItemType.AlternatingItem Then - Dim txtBox As TextBox CType(e.Item.FindControl
("txtBox"), TextBox) - Dim litFor As Literal CType(e.Item.FindControl
("litFor "), Literal) - litFor.Text LABEL NAME
- End If

Visual Studio .Net 2005 (Whidbey)
- Available Q1 05
- ASP.NET Server Control will now generate Section
508 compliant markup by default - Option you can set at page/site level to turn off
up-level client scripting for accessibility
compliance reasons. - Built-in compliance checking tool that can
automatically validate for both 508 and WCAG
(level 1 and 2) compliance
