Hiding user control in asp.net?

Hi everyone,





I am currently developing an application that will allow multiple users to chat. and i was wondering that if i have different users and i want them to take turns in using the the chat





Can i have it that a variable that will be stored in my global.asa file or my database or xml file will let certain buttons not be used?





I.e if it is players 1 turns to talk. all player two will see is a text area to receive the message?





I am using asp.net and asp buttons( control)





Can this be done as i was told that each user receives a separate web page due to the fact that each http request is different.Hiding user control in asp.net?
i am not sure about the solution.





probably you can implement singleton, where you use only one instance of the object %26amp; user cannot instantiate any more object and only access particular instance of it.





this article would help,

in this singleton class, you can make those buttons on your user control enabled = false or visible =false.








or may be you can use a static property which you can use to set the visibility of button.





but i think it is better to implement singleton as you can use single object for every chat session.
