ComboBox, TagBox - Keyboard navigation behavior has been changed

What Changed

In v24.1, keyboard navigation for the DevExpress Blazor ComboBox and TagBox components were reworked. Now keyboard navigation is implemented on the client and works seamlessly. When a user navigates within the drop-down list, the editor's value is not updated that helps us improve performance. To update the editor's value, the user now should press the Enter key or click an item.

The following shortcuts were changed or added:

v23.2 or earlier v24.1
To open the drop-down list Arrow Down Alt + Arrow Down
To close the drop-down list Alt + Arrow Down Alt + Arrow Up
TagBox only: To cancel tag editing Esc

Reasons for Change

This change helps us ensure consistent behavior with other Blazor components and improve performance. The new behavior also conforms to accessibility standards.

Impact on Existing Apps

Users now need to use new shortcuts to open and close the component's drop-down list.

How to Update Existing Apps

Recommended Approach
There is no need to change your application, just take into account that end-users now should use new shortcuts to open/close the drop-down list.

Temporary Solution (Not Recommended)
You can temporarily switch to the previous ComboBox/TagBox implementation. To do this, set the following properties to true:

IMPORTANT: These properties will be removed in v24.2. Use them only as a temporary solution.
