React Check Box
DevExtreme Accessibility Compliance
DevExtreme component libraries meet a variety of WCAG and Section 508 compliance standards. To assess this demo’s accessibility level, click the Run AXE® Validation button to launch the AXE® web accessibility evaluation tool.
All trademarks or registered trademarks are property of their respective owners. AXE® Terms of Use
The overall accessibility level of your application depends on the CheckBox features used.
To give you the ability to edit code on the fly, the demo uses SystemJS. For this reason, launching the demo takes some time. We strongly recommend that you do not use this approach in real projects.

The component supports the three state mode. In this demo, the enableThreeStateBehavior property of the "Three state mode" CheckBox is enabled. You can cycle through the states of this CheckBox in the following order:
Indeterminate → Checked → Unchecked → Indeterminate → ...
Specify the onValueChanged property to handle value changes. In this demo, the value of the "Handle value change" CheckBox is passed to the "Disabled" CheckBox. Click the first CheckBox to see how it affects the second one.
You can use the iconSize property to specify custom dimensions for the CheckBox. To add a label to the CheckBox, specify the text property.
