I have a scenario where i have modules, each module has sections and each section has programs.

So, I am creating groups during runtime in my program based on modules.

GetModules()

For  each module

 ExBar1.Groups.Add(ModuleID)
 ExBar1.Groups(ModuleID).Text = ModuleName
 ExBar1.GroupSettings.Style = Infragistics.Win.UltraWinExplorerBar.GroupStyle.ControlContainer

GetSections() based on module

For each section

 ContainerCntl = New Infragistics.Win.UltraWinExplorerBar.UltraExplorerBarContainerControl
  ContainerCntl = ExBar1.Groups(ModuleID).Container

In each ContainerCntl, I am adding a Tree by name TreeCntl

 TreeCntl = New Infragistics.Win.UltraWinTree.UltraTree
 ContainerCntl.CreateControl()
  ContainerCntl.Controls.Add(TreeCntl)

GetPrograms() based on Sections

Within TreeCntl, I am adding UltraLabel and another SubTree where SubTree Actually loads Programs and label displays name of the section

So,

 Try
                            SubTreeLabel = New Infragistics.Win.Misc.UltraLabel
                            ContainerCntl.CreateControl()
                            ContainerCntl.Controls.Add(SubTreeLabel)
                            'TreeCntl.CreateControl()
                            'TreeCntl.Controls.Add(SubTreeLabel)
                     

                            SubTreeCntl = New Infragistics.Win.UltraWinTree.UltraTree
                            ContainerCntl.CreateControl()
                            ContainerCntl.Controls.Add(SubTreeCntl)
                            'TreeCntl.CreateControl()
                            'TreeCntl.Controls.Add(SubTreeCntl)

I have a problem over here, Do i need to Create Controls under ContainerCntl and add them or else create them under TreeCntl and Add them. If I do the second way, it is not displaying them but first one is working fine.

Help me in this.
