HI!, Hope my TITLE is right... not pretty sure.....Is there a way i could achieve this and have the same functionality with this rather than doing checkboxes="true" because i will be using both radio button and checkbox. the controls depend on the parameter of the parent form in which for example when i call Form A. radiobutton will appear and when i call Form B checkbox will appear. 

I could not implement the example we have here at the site and it only take effect when i enable checkboxes="true". i have successfully bind the labels with the database to the radtreeview but the two control event are not. hope you could help me out with this one.. been trying a lot of ways for days.  :-(

below is a sample of my code hope you guys could understand it. :-)

thanks in advance and more power to telerik.......
