Hi, need some further detail.

What should the expression be for the text box that is storing the data?
And what should the expression be for the text box that is retrieving the data?
What is id and column ?
Where should the rest of the function be called? such as the onInit() OR is it called automatically on each render?

Hi,
Is there also a special method like On_Unload that can be used inside a custom code?

Thanks,

Joefer

Samsonfr,

Yes, it turns out that even if the hashtable key is user-specific and we do only adds and deletes (not updates to items from other users), we do need to make access to the hashtable collection thread-safe. I updated the blog. Thanks for pointing this out!

Thanks for sharing this with us. I was not aware of the multi-paging behavior.

Shouldn’t you protect yourself against multithreaded issues? Multiple threads can access your static hashtable at the same time, shouldn’t you use locks?
