Hi ali,
The ComboBox component has a different feature set compared to the MultiColumn ComboBox, which is designed to support grid-like functionalities such as paging. For instance, to enable paging in MultiColumn ComboBox, you can set the AllowPaging property to true, which will add a pager at the bottom of the dropdown, allowing smooth navigation through data pages.
If you’re encountering specific issues with the MultiColumn ComboBox in your sample, please share the details. We’d be happy to review and resolve any specific concerns or bugs to improve your experience.
Thank you for your understanding, and we’re here to assist further as needed.
