Thank you for contacting us.
Decorating checkboxes inside RadTreeView control with RadFormDecorator is not a supported scenario and we do not have plans to implement such integration. Nevertheless, you can find attached a sample page, which demonstrates two possible approaches for such integration:
- Adding the decorator classes in the OnClientNodeChecking event handler.
- Removing the preventDefault() method of the TreeView when a checkbox is decorated.
You are right, however, that the description of the demo mentions the RadTreeView control while the RadTreeList control is used in the example. I will fix the description. I have also updated your Telerik points for helping us improve the quality of our online resources.
