Hi,

I would like to use static property to stored some shared BO instance and data (as suggested by SF). Beside, I also would like to implement "auto requery" if any underlying data changed at server.



Anyway to make sure "auto requery" doesn't crash the web app? e.g. while ServerDataChanged event fired, there might be record populating taking place for ASPX. It I try to re-fill at that time, it might crash the system. I was thinking to use lock() statement to lock another static object for this purpose. But where should I do so?



Please advice. Thank you

Hi,

Thank you for sharing.

However, I still interested to know, how to prevent crash when I reload my cache.

As ASP.NET is multi threading, and as the sample posted using timer to reload cache. What will happen when ASPX is using the cache data, at the same time the timer fired and cache reload? As sometime we might not able to use lock() statement to handle this. For example, I bind my cache to GridView, GridView is populating row in ASPX, at the same timer triggered reload cache code executed.



Please advice



Thank you

Just create a static object on which to Lock when you call these methods.  If you have a static object that you Lock, it will resolve the synchronization locking issues.

Hi,

But GirdView row population is only happen may be in Page.DataBind() or Page.Render(). Do you meant I need to override them?

Without me spending the time to totally flesh this out I cannot give you exacts. But it is logical that you may have to unbind and rebind when a refresh of the cache is executed.
