My module may optionally load one or more of several user controls.

default view: list of options
User selects one or more options by clicking check boxes and then clicks "Go"

Based on options checked the appropriate user controls are dynamically loaded to a place holder using this code:

            Dim objPortalModuleBase As PortalModuleBase
            objPortalModuleBase = CType(Me.LoadControl(controlName), PortalModuleBase)
            objPortalModuleBase.ModuleConfiguration = Me.ModuleConfiguration
            objPortalModuleBase.ID = System.IO.Path.GetFileNameWithoutExtension(controlName)

            Me.phMain.Controls.Add(objPortalModuleBase)
           
I need to pass a parameter to each user control, on loading, in order to populate it with the correct data. How can this be done?

I have tried using ViewState unsuccessfully and have read of problems with ViewState between dynamically loaded controls. I do recall a solution but cannot find it when I search.

Perfect sense, thank you. It works just as fine

That's going to cause some trouble.  Why can't you see the class of the control?
