Sub Page_Load()
If Not Page.IsPostBack Then
Session(“bool”) = “Open”
End If

End Sub

sub page_loadcomplete()
‘ Setup drop down
ddlItems.Items.Clear()
ddlItems.Items.Add(“”)
If Not Session(“bool”) = “Open” Then ddlItems.Items.Add(“Open”)
If Not Session(“bool”) = “Closed” Then ddlItems.Items.Add(“Closed”)

end sub

Sub Click_Submit(ByVal s As Object, ByVal e As EventArgs)
If ddlItems.SelectedValue = “Open” Then
Session(“bool”) = “Closed”
ElseIf ddlItems.SelectedValue = “Open” Then
Session(“bool”) = “Closed”
End If
End Sub
