Hello,

We are using the Prometheus Calendar control as a datepicker similar to the Shared Calendar Example.

One of our customers is running the app through HiSoftware's AccVerify tool to ensure the application is Section 508 compliant.

If i run the shared calendar example through the tool and clear the date fields, the control is failing with the following errors:

<snip>
Rule: 1.1.2 - All INPUT elements are required to contain the alt attribute or use a LABEL.

Failure - INPUT Element, of Type TEXT, found at Line: 183, Column: 110
Failure - INPUT Element, of Type TEXT, found at Line: 187, Column: 129
Failure - INPUT Element, of Type TEXT, found at Line: 187, Column: 215

<snip>

If i run the example through the tool without clearing the fields, it generates the following warnings that are still considered to be failures:

<snip>
Rule: 1.1.2 - All INPUT elements are required to contain the alt attribute or use a LABEL.

Warning - INPUT Element, of Type TEXT, found at Line: 183, Column: 110 contains a non-empty 'value' attribute. This is a practice referred to as "self-labeling." Self-Labeling is argued to be accessible under Priority One or Section 508 guidelines/standards. We recommend using a Label as the Preferred method or the use of an 'alt' attribute to make this element accessible.

In the example, there is a label who's 'for' attribute is being set to '<%= RadDatePicker1.DateInput.ClientID + "_TextBox" %>'

but there are two other inputs rendered for each datepicker that still violate the 508 1.1.2 rule.

In my page, I tried adding the AssociatedControlId property on the label that precedes the control on the form, but I'm still receiving failures as well.

Any suggestions?

I'd like to add that we've been able to reproduce this in a sandbox environment easily.

Here's a simple page using the control:

    
            <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="RadDatePicker.aspx.cs" Inherits="WebApplication.RadDatePicker" %> 
        
            <%@ Register assembly="Telerik.Web.UI, Version=2007.3.1314.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" namespace="Telerik.Web.UI" tagprefix="telerik" %> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
        
            <html xmlns="http://www.w3.org/1999/xhtml" > 
        
            <head runat="server"> 
        
                <title>RadDatePicker Prometheus 1.1.2 INPUT element 508 Compliance Issues</title> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server"> 
        
                    <h1>RadDatePicker Prometheus 1.1.2 INPUT element 508 Compliance Issues</h1> 
        
                    <asp:scriptmanager runat="server"></asp:scriptmanager> 
        
                    <asp:Label ID="uxLabelDate" runat="server" AssociatedControlID="RadDatePicker1" Text="Date:" /> 
        
                    <telerik:RadDatePicker ID="RadDatePicker1" Runat="server"></telerik:RadDatePicker> 
        
                </form> 
        
            </body> 
        
            </html>

Here's the error:

Rule: 1.1.2 - All INPUT elements are required to contain the alt attribute or use a LABEL.

Failure - INPUT Element, of Type TEXT, found at Line: 55, Column: 150
Failure - INPUT Element, of Type TEXT, found at Line: 55, Column: 238

Here's the output lines:

55: <TD class=inputCell style="WIDTH: 100%"><SPAN class=radInput_Default id=RadDatePicker1_dateInput_wrapper style="DISPLAY: block; WHITE-SPACE: nowrap"><INPUT class=radEnabledCss_Default id=RadDatePicker1_dateInput_text style="WIDTH: 100%"><INPUT id=RadDatePicker1_dateInput style="BORDER-TOP-WIDTH: 0px; PADDING-RIGHT: 0px; DISPLAY: block; PADDING-LEFT: 0px; BORDER-LEFT-WIDTH: 0px; FLOAT: right; VISIBILITY: hidden; BORDER-BOTTOM-WIDTH: 0px; PADDING-BOTTOM: 0px; MARGIN: -18px 0px 0px; OVERFLOW: hidden; WIDTH: 0px; PADDING-TOP: 0px; HEIGHT: 0px; BORDER-RIGHT-WIDTH: 0px" name=RadDatePicker1$dateInput><INPUT id=RadDatePicker1_dateInput_ClientState type=hidden name=RadDatePicker1_dateInput_ClientState></SPAN></TD>

Thanks,
Rick
