I'm creating a very simple chat application. It has an ASP.NET web page as front-end and a WCF service as back-end for storing the
messages to a database.
Everything works great except one thing; when Browser A enters a chat message I want Browser B to see the message as soon as possible (yeah, I know, that's the purpose of a chat).
What I've done so far is to setup a trigger within the UpdatePanel, like this:
<Triggers>
<asp:AsyncPostBackTrigger ControlID="chatTimer" EventName="Tick" />
</Triggers>
which uses a timer:
<asp:Timer ID="chatTimer" runat="server" OnTick="chatTimer_Tick" Interval="1000" />
Is this the best approach or is there a better, yet simple, way to accomplish updating of
messages. One drawback with this solution is that the textbox used to enter chat
messages loses focus every time the Tick event runs.
Any piece of feedback or advice regarding updating of
messages is appreciated.
Thank you!
