Hi Gandhi,
Thank you for your interest in Syncfusion Products.
We
regret to let you know that currently there is no direct builtin
support for autocomplete in ComboBoxBarItem. We have made a simple
workaround that helps you in achieving your requirement.
Please have the sample and let us know if it helps you.
