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());
    }
}
