ListView and LinqDataSource. Delete item

[shapper]

Hello,

I have a ListView connected to a LinqDataSource. It uses a table,
named Tags, with 2 fields: TagId and Text.

I need to add a column named active. For this I created a
LinqDataSource custom selecting:

Private Sub ldsTags_Selecti ng(ByVal sender As Object, ByVal e As
LinqDataSourceS electEventArgs) Handles ldsTags.Selecti ng
Dim database As New CodeDataContext
Dim tags = From t In database.Tags _
Select t.TagID, _
t.Text, _
Active = t.FilesTags.Any Or
t.ArticlesTags. Any
e.Result = tags
End Sub

As you see I added a new column, Active, create by the relation of
Tags tables and other tables.

Now when I try to delete a record in the ListView it does not work
anymore. I get the following error:

Row not found or changed.

System.Data.Lin q.ChangeConflic tException: Row not found or changed.

What can I do to fix this?

Thank You,

Miguel
