DevExpress Blazor components are designed to help you create web applications that conform to accessibility guidelines. This section describes accessibility areas that we take into consideration when developing our components.
Many DevExpress Blazor components comply with WCAG 2.2 (Level AA), Section 508, and EN 301 549 standards. To learn more about how Blazor components satisfy these requirements, refer to the DevExpress Accessibility Conformance Report (ACR).

Keyboard accessibility is one of the most important principles of Web accessibility because it cuts across disability types and technologies. Most Blazor components support keyboard navigation, which allows users who rely on alternative input methods to navigate and interact with application content.
The table below lists components that support keyboard navigation.
- All component features include keyboard support.
- Several component features do not include keyboard support.
We are committed to ensuring that our components comply with WAI-ARIA standards. Most Blazor components contain WAI-ARIA attributes, such as role, property, and state information, to provide additional semantics and improve accessibility.
Elements inside Blazor components, such as buttons, provide information intended for assistive technology tools. This information is maintained in DxBlazorStringId enumeration strings that have the A11y_{string_name} name pattern, for instance, A11y_Pager_FirstPage.
You can customize string values with our localization mechanism.
You can use HTML attributes (including ARIA attributes) to configure Blazor components.
The following code sample specifies the aria-label attribute for a TextBox:
<DxTextBox aria-label="User's first name" />
Refer to the following topic for additional information: HTML Attributes in Editors.
DevExpress Blazor components work well in mobile applications. Our components support responsive render, touch targets, and mobile-friendly interfaces. Refer to the following section for the list of supported browsers: Supported Browsers.
Users can utilize various screen reader software and other assistive technology tools. In our assessments, we ran automatic tests with the Axe accessibility testing engine and WAVE web accessibility evaluation tool. We also conducted manual tests with the NVDA screen reader.
You can apply different size modes to DevExpress Blazor components and their elements. Larger control sizes simplify information perception and control interaction (useful for people with vision impairment and motor disabilities).
Blazor components do not support right-to-left languages.
