Thank you for writing.
I am not sure that I understand correctly your complete requirement. Telerik UI for WinForms suite doesn't offer a query builder control.
However, I suppose that the RadExpressionEditor
might be suitable for your case. The following Knowledge Base article is quite useful for creating a standalone expression editor which allows you to build complex expressions: http://www.telerik.com/support/kb/winforms/forms-and-dialogs/details/create-standalone-radexpressioneditor-form
If it is not applicable, it would be greatly appreciated if you can provide more details about the exact goal that you are trying to achieve. Thus, we would be able to assist you further. Thank you in advance.
I am looking forward to your reply.
