Thank you for contacting me.
I am glad to hear that you managed to resolve your issue.
Yet, if you want to create groups based on a database, you should programmatically make a RadPanelBarGroupElement for each row of a particular DataTable. In addition, the caption text can be received from a specific column in that table. We are using Access in our examples, because they are easier to setup.
I am attaching a project demonstrating how to create the groups depending on the database. Depending on your preferences, you can use SQL Server with our controls as well.
If you have any additional questions, do not hesitate to contact me. I will glad to assist you.
