Hi, I have downloaded the WebControls and tries to get DNNTree to work in a UserControl. I took the following subroutines as a start.

   SetTreeDefaults() 
   PopulateTree()
   and
   Protected Overrides Sub OnInit(ByVal e As System.EventArgs)
      MyBase.OnInit(e)
      DotNetNuke.UI.Utilities.ClientAPI.HandleClientAPICallbackEvent(Me.Page)
   End Sub

Also I registered in the .ascx the DotNetNuke.UI.WebControls, and set up the control exactly as in the DNNTree.aspx example. however I see nothing. No errors, the code runs through all fine, but nothing shows up. Any ideas what I'm missing? I have DNN3.2.2 and the WebControls are the last versions available on http://www.dotnetnuke.com/Default.aspx?tabid=874. IE6

Thanks,
/Rob

Thanks Jon! This is what I see from the source of my app. What I've done is just to add an extra usercontrol to the HelloAJAX example called DNNTree.ascx, registered it in ModuleDefinitions and run in together with the rest of the HelloAJAX example files. The module shows up nicely together with the other two, and the code is runs through SetTreeDefault() nice and easy, but nothing shows up.
