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. |
