For debug=true or for trace enabled=true, I don't get any compilation output. Looking at the source of the page, it just stops in the middle of building an html table. Without any debug/trace statements and without trying to use the native sql client, I get 3 javascript errors.
Type is no defined on line:
Type.registerNamespace('AjaxControlToolkit');
(this looks to cause the following 2 errors)
Sys is not defined:
Sys.WebForms.PageRequestManager._initialize('ScriptManager1', document.getElementById('formc'));
Sys is not defined:
Sys.Application.initialize();
