Hi EE,

I have an app that uses the membership provider.  
I designed my sql server 2005 tables with the foreign key UserID uniqueidentifier.
I want to use Linq to sql to bind my forms, fields, etc. and was wondering what would be the best way to do this, when I have to include the UserID in all my inserts/updates.
Please provide an example.
Thank you

Hi,

You could do something simple like:

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load

        If Not Page.IsPostBack Then
            If User.Identity.IsAuthenticated Then
                Dim u As MembershipUser = Membership.GetUser(User.Identity.Name.ToString())
                Session("UserID") = u.ProviderUserKey.ToString()
            End If
        End If

        Dim dc As New MyLinqClassesDataContext()
        Dim q = From a As MyData In dc.GetTable(Of MyData)() Where a.UserID = Session("UserID")

    End Sub

Hope this helps!

/Carl.
