New Notification based on New Posting

Question

I am maintaining a student Portal constructed in 3 tier architecture.

This Student Portal has lot of sections including a dynamic noticeboard.

I want to implement some thing like notification whenever a new notice is posted to the noticeboard.

Please help me out , how can i do it

EDIT

I am using a datalist control as the notieboard. The datasource of the datalist is a table named "Student_Notice" in the database.

The notices are posted by the admin side and students in their respective account view the notice.

This notice is common for all the students.

What I need is when ever there is a new notice added i.e a new record inserted in the Student_Notice table by the admin ,Whenever the students log in , One should be intimated regarding the new notice being posted via a notification mechanism just like we have in this very Forum.

For e.g I have posted this question in the forum if some one replies to my question , I get a notification , that there is one reply to your question.

Hope it is clear now.

1. Make a ajax call to the Database from the Datalist
2. Call that function for every secon.

How ??

I would appreciate, if you could provide any reference.

No this is not good solution to make continuous call to Database server at specific time interval. It may increase response time from the server. what i prefer is please use singnalR.
from the following link you can get more idea about it. http://www.asp.net/signalr

Hi Kunal,

Please use ASP.NET SignalR[^] for your requirement.

About ASP.NET SignalR

Microsoft say "ASP.NET SignalR is a new library for ASP.NET developers that makes developing real-time web functionality easy. SignalR allows bi-directional communication between server and client. Servers can now push content to connected clients instantly as it becomes available. SignalR supports Web Sockets, and falls back to other compatible techniques for older browsers. SignalR includes APIs for connection management (for instance, connect and disconnect events), grouping connections, and authorization."

Thanks
