Did you actually trace to see that the BO gets disposed in the masterpage dispoal?  That would be the first thing that I would do.  The only other reason that it would not dispose is there is another class that has a reference to the object...or an event handler.  If you are adding a handler to the BO and not removing the handler then you can have an object stick around as well.

Hi,

I have initialized a BO to MasterPage's private field.







How could I dispose it? I tried to override MasterPage.Dispose() and call BO.Dispose(). However, it is not been released. I check using ANT profiler, it still show the BO is still at memory.



Any ideas?



Thank you
