Answer 1

Try to set :

 lblScripter.Text = @"<script type=""text/javascript"">SP.SOD.executeOrDelayUntilScriptLoaded(function() {showInfo('" + MessageShow + "');}, 'sp.js');</script>"

Most likely this will solve your problem of calling the SP.UI.Status javascript functions before they have been loaded.
