Undo update the update panel when the application variable changes

Question

I have a multi-user application, I need to update the update panel when one of the users changes the state of the application variable to true.

What is the best way to do this?

I tried with a timer, but there was a postback on the timer mark on all pages.

thanks

------- EDIT --------

Thanks for the suggestions, I will try to better explain my problem.

I have a large database shown in a related gridview. Most users only read data, but someone can edit. It is very important that changes immediately appear to all users who see the GridView. The best solution I found is to define a variable for the application and users who are editing to set this variable to true. All other users update the GridView only if the application variable is true, otherwise they do nothing.

This is a good decision?
