WAI-ARIA Support
Updated on Oct 7, 2026
Enabling WAI-ARIA support
The RadGrid control offers WAI-ARIA support which can be easily enabled by setting the EnableAriaSupport server property to true.
RadGrid ARIA attributes are lower case. They are shown in the table below.
| Control | Attributes and roles |
|---|---|
| RadGrid | aria-haspopup |
| RadGrid | aria-hidden, aria-readonly, aria-multiselectable, aria-checked, aria-grabbed, aria-dropeffect, aria-level, role:group, role:listitem, role:textbox, role:button, and role:checkbox. |
| Inner controls | ARIA is enabled where supported in column editors, filter headers, the pager, and other inner controls. |
An issue with the use of WAI-ARIA in HTML documents is that they don’t validate. When you run a HTML document containing ARIA attributes through the W3C Validator it shows errors in the results for any ARIA attributes. The DOCTYPE declarations do not include any information about the WAI ARIA attributes and you cannot have a valid document which includes elements, attributes, and attribute values, not detailed in its DTD’s.
