Adding a tree to an ultraexplorerbar and populating it

Hi

Having loads of fun trying to get this to work. I can add a tree to an ultraexplorerbar in the visual designer and it all looks OK. I actually need to mimic a menu system with groups as the top level items and then an ultratree under each group.

Unfortunately it all seems to work OK, but I never get any nodes to display. Can someone tell me what I need to do to the following code to make it work. Basically I have crated a method in an inhertied object of the exporerbar which I call passing a dataset.

DEF VAR iCount AS INT NO-UNDO.

FOR EACH eMenu WHERE

        eMenu.TopLevel = TRUE

        BY eMenu.MenuOrder:

            oGroup = NEW Infragistics.Win.UltraWinExplorerBar.UltraExplorerBarGroup().

            oTree = NEW OSL.OSLMenuTree().

            oContainer = NEW Infragistics.Win.UltraWinExplorerBar.UltraExplorerBarContainerControl().

            oRoot = NEW Infragistics.Win.UltraWinTree.UltraTreeNode().

            oContainer:Controls:Add(oTree).

            oContainer:Name = "Container" + STRING(iCount).

            oTree:Dock = System.Windows.Forms.DockStyle:Fill.

            oTree:ImageTransparentColor = System.Drawing.Color:Transparent.

            oTree:NodeConnectorColor = System.Drawing.SystemColors:ControlDark.

            oTree:Name = "Tree" + STRING(iCount).

            oRoot:Key = "ROOT".

            oRoot:Text = "ROOT".

            oTree:Nodes:Add(oRoot).

            oExplorerBar:Controls:Add(oContainer).

            oGroup:Key  = "GROUP" + STRING(iCount).

            oGroup:Text = eMenu.ItemName.

            oGroup:Settings:Style = Infragistics.Win.UltraWinExplorerBar.GroupStyle:ControlContainer.     

            oGroup:Container = oContainer.

            oContainer:Dock = System.Windows.Forms.DockStyle:Fill.

            THIS-OBJECT:Groups:Add(oGroup).

            iCount = iCount + 1.   

END.

Anyone any idea what I'm doing wrong. I'm reasonably new to all this. I was hoping to get round the position stuff and size by making it all dock fully. I clealy need somethng else or maybe the order of things need to change. I did create an example in the visual designer and I worked form that. Unfortunately the VD was doing all this during initialisation and my method runs from a form and is post init.

Thanks
