check selected

Hej Eksperter

MyConnection.Open()
oRs = ("SELECT NetsiteUsers.ID, NetsiteUsers.Username FROM NetsiteUsers INNER JOIN ProjectUsers ON NetsiteUsers.ID = ProjectUsers.UserID WHERE ProjectUsers.ProjectRootID = " & ProjectRootID)
ADP4 = New SqlDataAdapter(oRs, MyConnection)
ADP4.Fill(DS2, "NetsiteUsers")
MyConnection.close
userid2.DataTextField = "username"
userid2.DataValueField = "id"
userid2.DataSource = DS2.Tables("NetsiteUsers").DefaultView
If Not (Page.IsPostBack)
    userid2.DataBind()
    For i=0 To userid2.Items.Count()-1
        If userid2.Items(i).Value.ToString()=DS.Tables("Projects").Rows(0)("projectmanagerid").ToString() Then
          userid2.Items(i).Value.SelectedItem
        End If
    Next
End If

Jeg forsøger at få den til at selecte den manager der står i databasen men får fejl i den her linie:

userid2.Items(i).Value.SelectedItem

'SelectedItem' is not a member of 'String'
