Problem with FormView

Ok I have a new page which I want to use a FormView. I create an object which exposes a method returning a list(of Server). Now in the designer I can drop the FormView on the page, create the ObjectDataSource from the method and I see all the properties.
Ok now my code (object)
Imports Microsoft.VisualBasic
Imports Microsoft.SqlServer.Management.Smo
Imports Microsoft.SqlServer.Management.Common
imports System.Collections.Generic
Public Class SQLServer
private fgss as new list(of Server)
public sub new()
End Sub
public sub new(fgs as server)
fgss.Add(fgs)
End Sub
public function GetSever() as list(of server)
return fgss
End Function
End Class
and in the page load of the page:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Me.Session.Item(STR_LoginInfo) IsNot Nothing Then
linfo = Me.Session.Item(STR_LoginInfo)
xServer = linfo.SQLServer
If xServer Is Nothing Then
Exit Sub
End If
else
linfo = New LoginInfo
linfo.ServerName = STR_QLExpress
linfo.UseIntegratedSecurity = True
xServer = linfo.SQLServer
Session.Add(STR_LoginInfo, linfo)
End If
dim ss as New SQLServer (xserver)
me.FormView1.DataSourceID=nothing
me.FormView1.DataSource=ss
me.FormView1.DataBind()
End Sub
The line me.FormView1.DataSource=ss tells me that the source "Data source is an invalid type. It must be either an IListSource, IEnumerable, or IDataSource." Now all was good in the designer so why the problem???
