You’re idea helped me get over one obstacle, but I now seem to have one more.
Below is my code from Deafult.aspx.

MgUserInformation userInfo = new MgUserInformation("Administrator", "admin");
MgSite site = new MgSite();
site.Open(userInfo);
String sessionId = site.CreateSession();
String webLayout = "Library://DevTV/HelloWorld.WebLayout";
Globals.gSessionID = sessionId; //Holds my session ID value

When the map comes up, nothing is selected…..you’ve been such a “HUGE” help,
could you review what I have and give me you opinion please…many thanks.
