try it binding in is not postback
Reference

If you bind inside page load you will always get the first value of the dropdown list.

private void Page_Load()
{
   if (!IsPostBack)
   {
        //bind your dropdown here
   }
}

In VB

Sub Page_Load
  If Not IsPostBack
    ' bind your dropdown list
    Validate()
  End If
End Sub

Storing Connection string you can use web.config file

Ideally you should put another question here. But You should use web.config for connection-string file for this. Also there is gloabal.asax which can help you.
