Accessibility Support
- 2 minutes to read
Many DevExpress WinForms controls comply with WCAG 2.2 (Level AA), Section 508, and EN 301 549 standards. To learn more about how WinForms controls satisfy these requirements, refer to the DevExpress Accessibility Conformance Report (ACR).
Limitations
The following table lists known Editors and Simple Controls limitations according to the WCAG 2.x standard:
WCAG 2.x Criterion | Exception Description |
|---|---|
2.1.1 Keyboard (Level A) | Users cannot focus ButtonEdit buttons from keyboard. Users cannot use keyboard to focus buttons within the CalcEdit dropdown window. Users cannot use keyboard to activate the link that is focused within the HyperLinkEdit. As a workaround, you can call the HyperLinkEdit.ShowBrowser method on the KeyDown event. Users cannot change RatingControl value from keyboard. |
4.1.2 Name, Role, Value (Level A) | TokenEdit does not provide assistive technologies with accessible information about tokens. RadioGroup does not provide assistive technologies with accessible information when users change the control value. DateEdit does not provide assistive technologies with accessible information when a user navigates through dates in the popup, only the day number is red. |
2.5.8 Target Size (Minimum) (Level AA 2.2 only) | The SpinEdit‘s spin buttons contain smaller pointer input areas than 24x24 pixels (depending on the applied skin). As a workaround, use Touch Skins to enlarge pointer input areas in all DevExpress components. |
Note
Limitations above are listed for reference and may not cover all available scenarios. Accessibility features of your application depend on your implementation of Editors and Simple Controls.
