Hi @all

I'm creating a DNN Module with three ascx-files. The first control (view) shows two LinkButtons and one panel. When I click on the first LinkButton, the second ascx-control will be loaded into the panel. The second LinkButton do the same with the third ascx-control. I load the controls with panel1.controls.add(second.ascx).
This works so far. But on my second ascx I've got two DropDownLists. The first will be filled wenn the module is loading. The second will be filled, when the selection in the first is done (autopostpack). 

My problem is: When I do the selection in the first DropDown on the second ascx, the second ascx disapears. how can I solve this?

Or is there an other way to load ascx-files within my dnn module?

Thanks

I commonly develop DotNetNuke custom modules using multiple ascx pages.  I always have a "master" ascx control that is merely used to control which ascx should be loaded depending on a parameter in the querystring.  It looks something like this:

If Request.Params("go") = "sum" Then
                Dim objModule As Entities.Modules.PortalModuleBase = Nothing
                objModule = CType(LoadControl("DNNReportingPolSum.ascx"), Entities.Modules.PortalModuleBase)
                objModule.ModuleConfiguration = ModuleConfiguration
                Controls.Add(objModule)
            ElseIf Request.Params("go") = "search" Then
                Dim objModule As Entities.Modules.PortalModuleBase = Nothing
                objModule = CType(LoadControl("DNNReportingSearch.ascx"), Entities.Modules.PortalModuleBase)
                objModule.ModuleConfiguration = ModuleConfiguration
                Controls.Add(objModule)
            ElseIf Request.Params("go") = "view" Or Request.Params("go") = "act" Or Request.Params("go") = "pend" Then
                Dim objModule As Entities.Modules.PortalModuleBase = Nothing
                objModule = CType(LoadControl("DNNReportingView.ascx"), Entities.Modules.PortalModuleBase)
                objModule.ModuleConfiguration = ModuleConfiguration
                Controls.Add(objModule)
            ElseIf Request.Params("go") = "ind" Then
                Dim objModule As Entities.Modules.PortalModuleBase = Nothing
                objModule = CType(LoadControl("DNNReportingIndividual.ascx"), Entities.Modules.PortalModuleBase)
                objModule.ModuleConfiguration = ModuleConfiguration
                Controls.Add(objModule)
            ElseIf Request.Params("go") = "ws" Then
                Dim objModule As Entities.Modules.PortalModuleBase = Nothing
                objModule = CType(LoadControl("DNNReportingWorksite.ascx"), Entities.Modules.PortalModuleBase)
                objModule.ModuleConfiguration = ModuleConfiguration
                Controls.Add(objModule)
            ElseIf Request.Params("go") = "pdf" Then
                Dim objModule As Entities.Modules.PortalModuleBase = Nothing
                objModule = CType(LoadControl("DNNReportingGenerate.ascx"), Entities.Modules.PortalModuleBase)
                objModule.ModuleConfiguration = ModuleConfiguration
                Controls.Add(objModule)
            Else
                Dim objModule As Entities.Modules.PortalModuleBase = Nothing
                objModule = CType(LoadControl("DNNReportingStart.ascx"), Entities.Modules.PortalModuleBase)
                objModule.ModuleConfiguration = ModuleConfiguration
                Controls.Add(objModule)
            End If

Those 4 lines of code are all you need to load in an ascx control and you don't have to bother with asp panels to control visibility of controls

Rodney,

As you see in the example in the post above yours, a module is nothing but a control that inherits from PortalModuleBase. So all you need to do is:

Dim objModule As Entities.Modules.PortalModuleBase = Nothing
Dim myPath as string = "<REPLACE THE PATH TO THE MODULE HERE>"
objModule = CType(LoadControl(myPath + "<MyModule.ascx>")
objModule.Settings = Me.Settings
objModule.LocalResourceFile = Me.LocalResourceFile
