how to insert record with wpf databinding? - wpf

Question

im new to wpf, so please bear with me
i made a window for the purpose of managing "profile" records
while the navigation and updating is working
i cannot seem to get insertion working, as well
heres the very simple code
Imports System.Collections.ObjectModel
Public Class Window1
Dim WindowEntities As New DataEntities
Dim WindowList As ObservableCollection(Of Profile)
Function ProfilesViewSource() As CollectionViewSource
Return CType(FindResource("ProfilesViewSource"), CollectionViewSource)
End Function
Function DefaultView() As CollectionView
Return CollectionViewSource.GetDefaultView(ProfilesViewSource.View)
End Function
Sub Window_Loaded(ByVal sender As Object, ByVal e As RoutedEventArgs) Handles MyBase.Loaded
WindowList = New ObservableCollection(Of Profile)(From x In WindowEntities.Profiles Order By x.ProfileName)
ProfilesViewSource.Source = WindowList
End Sub
Private Sub btnSave_Click(ByVal sender As Object, ByVal e As RoutedEventArgs) Handles btnSave.Click
WindowEntities.SaveChanges()
End Sub
Private Sub btnAdd_Click(ByVal sender As Object, ByVal e As RoutedEventArgs) Handles btnAdd.Click
WindowList.Add(New Profile)
DefaultView.MoveCurrentToLast()
End Sub
Private Sub btnNext_Click(ByVal sender As Object, ByVal e As RoutedEventArgs) Handles btnNext.Click
DefaultView.MoveCurrentToNext()
End Sub
End Class
when i press add, i get a new empty record, when i fill it in, i see that the collection sees it, as there is an onform listbox showing the profiles, and it gets listed there, so its actually attached to the list, but the savechanges command does not insert it into the db
there may be some validation errors upon insert, but then i would get some indication, right? now its just silently failing. as if i never tied to commit changes
thank you very much for your help fellows
