AJAX TABCONTAINER Dynamically from acces database .... formatting problems

Hi

I am trying to populate a TabContainer from an Access Database, I have managed to nearly get it working , The Header is ok but The Details area is displaying vertically rather than horizontally so like

T

E

S

T

rather than TEST my code is :

  Dim myConnection As New OleDbConnection("PROVIDER=Microsoft.Jet.OLEDB.4.0; Data Source=c:\database\refresher.mdb")
            Dim myCommand As OleDbDataAdapter = New OleDbDataAdapter("select * from [User]", myConnection)
            Dim datset As DataSet = New DataSet()
            myCommand.Fill(datset, "User_Details")
            myConnection.Close()
            Dim usertbl As DataTable = datset.Tables(0)
            For i As Integer = 0 To usertbl.Rows.Count - 1
                Dim myRow As DataRow = usertbl.Rows(i)
                Dim opt1 = datset.Tables("User_Details").Rows(i).Item(1)
                Dim opt2 = datset.Tables("User_Details").Rows(i).Item(2)
                Dim opt3 = datset.Tables("User_Details").Rows(i).Item(3)
                Dim gv As New GridView()
                gv.DataSource = datset.Tables("User_Details").Rows(i).Item(1).ToString
                gv.DataBind()
                Dim tab As New AjaxControlToolkit.TabPanel()
                tab.Controls.Add(gv)
                tab.HeaderText = datset.Tables("User_Details").Rows(i).Item(1)

                tabContainer1.Tabs.Add(tab)

            Next
        End If

I would imagine I have done something obvious and daft , so any help would be great !
