Radgrid - Section 508 related issues

[Kalidas Karunamoorthy]

Hi,

 

We using Telerik tools (Version Version=2009.3.1208.20) for our ASP.Net web development. We also have Radgrids with sorting and Pagination functionality enabled in our ASPX pages. From the 508 testing, we noticed the following issues with the Radgrid when pagination/sorting enabled.  

 

a)      When images are removed or certain alternate stylesheets are applied, the table pagination and sort image buttons disappear. (Please find the attachment TotalExceptionsTableWithCSSDisabled.PNG)

b)      When CSS is disabled on the page, the table pagination and sort image buttons display as buttons with no text (they display as a gray box).  (Please find the attachment ExceptionRequestCSSOff.PNG)

c)       Further more, the “Page Size” combo box at the end (at the footer) of the radgrid data table do not have explicit labeling. Is there a way we could add a explicit label to the page size drop down?

 

We have also identified few other section 508 issues with Radgrid and created separate service requests for them. Per response to those threads, we are grouping all 508 relates issues in this one single thread.  Please find the list of 508 issues attached.

Please provide me a guidance / option how to address these section 508 findings.

 

Thanks,

Hi Kalidas,

Straight to your questions:

    - To overcome the issue with the pager, I would suggest that you define your own PagerTemplate for the grid which uses regular buttons or image buttons. 
    - For ther sort arrow/button, you can try finding in the grid PreRender event and set its Text. However thus the buttons might not look good when the default styles are applied to them. Another option is to use GridTemplateColumns with custom HeaderTemplate. 
    - Note that RadComboBox cannot work with disabled javascript. Additionally, you can check out this topic for more infromation on how to customize the grid built-in pager. You can also take a look at the other topics in the same section.
    - The requirements described here would result in a breaking change in the grid rendering. We might consider them for future version. Currently you should be able to achieve such results with custom HeaderTemplate.
    - Regarding this thread: The text displayed before the page size combo is rendered in a <span> element. I will forward this to our developers so they change it to render in a <label> tag.

All the best,
Iana
