Please review the Using a Control that is not Integrated by Default article to learn more on possible solutions. In particular, you can implement a custom PropertyEditor or ListEditor as described below:

It is important to check out the documentation on this control:
WinForms Controls > Controls and Libraries > Editors and Simple Controls > Token Edit Control
ASP.NET Controls and MVC Extensions > DevExpress.Web > ASPxTokenBox
In addition, you can review examples our users created while working on similar tasks:
WinForms: What is the best approach to store and retrieve values from TokenEdit via ListEditor, TokenEdit based XAF property editor and more...
ASP.NET: Xaf Web - Create a custom ListEditor based on the ASPxTokenBox control, Custom token box property editor and more...
Let us know if you experience any difficulties with integrating the token editors in your XAF app. In this case, in addition to the sample where you tried to use it according to the docs I introduced above, please also elaborate a bit more on your planned usage scenario and expected results from the end-user's perspective.
We would also greatly appreciate it if you describe your planned use-case scenarios or exactly how and for what your end-users are supposed to use this token box control in your app.
If possible, attach screenshots, test samples and database to clarify expected results and user steps within the application UI. With that, we will be able to better understand your requirements and provide more specific solutions or consider improvements to our products for the future. Thanks in advance.
