I'm making a module and I'm trying to populate a combobox from code from here:

http://www.dotnetnuke.com/Resources/F...

Unfortunately it appears to be obsolete. I can't figure out how to get updated code that works.

Right now I'm using this:

Dim lc As New ListController()
Dim entryCollection As ListEntryInfo = lc.GetListEntryInfo("Region", "221")
cmbForwardState.DataTextField = "Text"
cmbForwardState.DataValueField = "Value"
cmbForwardState.DataSource = entryCollection
cmbForwardState.DataBind()

When I run the page, it doesn't do anything. :(

Note that the GetListEntryInfo method returns only a single ListEntryInfo object, not a collection or list that can be bound to a drop-down list control.

Depending upon whether you are using DNN 5.x or 6.x you will want to use one of the following methods of the ListController to return a collection of ListEntryInfo items:

DNN 5.x - GetListEntryCollection which returns a custom ListEntryInfoCollection.

DNN 6.x - GetListEntryInfoItems which returns a generic IEnumerable<ListEntryInfo> collection.

You will then be able to bind the returned collection to the list control as you are now doing.

I still can't seem to get it to work. This code crashes with:

DotNetNuke.Services.Exceptions.ModuleLoadException: Unable to cast object of type 'System.Collections.Generic.List`1[DotNetNuke.Common.Lists.ListEntryInfo]' to type 'DotNetNuke.Common.Lists.ListEntryInfo'. ---> System.InvalidCastException: Unable to cast object of type 'System.Collections.Generic.List`1[DotNetNuke.Common.Lists.ListEntryInfo]' to type 'DotNetNuke.Common.Lists.ListEntryInfo'.


Dim lc As New ListController()
Dim entry As DotNetNuke.Common.Lists.ListEntryInfo = lc.GetListEntryInfoItems("Region", "221")

Ahh got it! Here's the complete code to populate DNN 6 states list to a user control/module.

Dim lc As New DotNetNuke.Common.Lists.ListController()
Dim entryCollection As System.Collections.Generic.List(Of DotNetNuke.Common.Lists.ListEntryInfo)
entryCollection = lc.GetListEntryInfoItems("Region", "Country.US", 0)

With cmbForwardState
.DataTextField = "Text"
.DataValueField = "Value"
.DataSource = entryCollection
.DataBind()
End With
