Você deve habilitar o rastreamento da página ou aplicativo para que este exemplo funcione.

// Create a custom ControlCollection that writes
// information to the Trace log when an instance
// of the collection is created.
[AspNetHostingPermission(SecurityAction.Demand, Level=AspNetHostingPermissionLevel.Minimal)]
public class CustomControlCollection : ControlCollection
{
    private HttpContext context;

    public CustomControlCollection(Control owner)
        : base(owner)
    {

        HttpContext.Current.Trace.Write("The control collection is created.");
        // Display the Name of the control
        // that uses this collection when tracing is enabled.
        HttpContext.Current.Trace.Write("The owner is: " + this.Owner.ToString());
    }
}

' of the collection is created.
<AspNetHostingPermission(SecurityAction.Demand, _
   Level:=AspNetHostingPermissionLevel.Minimal)> _
Public NotInheritable Class CustomControlCollection
