I have created a default page on my custom module (default.ascx) and a settings page (settiings.ascx).

in my settings I can store the values of username, password and baseUrl for an external webservice that uses oAuth token authentication.  

What I am trying to do is when the module loads for the admin is if the setting value is null for the username, password or baseUrl i want the module setting to open so the admin can put these values in.

Here is a snippet of my code so far

if (((string)Settings["username"] != null) && ((string)Settings["username"] != ""))  {  username = (string)Settings["username"];  }  else  {  //open the settings module programmatically  }
