Inherits BasePage
Public Sub DetailsView1_InsertItem()
Dim photoAlbum As New PhotoAlbum()
TryUpdateModel(photoAlbum)
If ModelState.IsValid Then
Using myEntities As New PlanetWroxEntities()
myEntities.PhotoAlbums.Add(photoAlbum)
myEntities.SaveChanges()
End Using
Response.Redirect(String.Format("ManagePhotoAlbum? PhotoAlbumId={0}", photoAlbum.Id.ToString()))
End If
End Sub
End Class
