Problem with displaying a webpage on an iframe element on Mozilla firefox, Safari

Hi,


          I have this code which works fine when using ie.
string dummy;
            dummy = @"\\treining.com\trace\Performance Metrics\Dashboard\Rating\Web\LNOverview\dashboard.html";
            contentiframe.Attributes["src"] = dummy;


         But when using mozilla, it won't redirect to the sourc point of the webpage that is to be embedded on the iframe element.
          Is this a problem with the string that I used? Any other way to represent a string with backslashes?


Thanks in advance
