See more: C# ASP.NET Ajax Chat
currently I'm developing a web chat using ASP.NET with Ajax. But the problem i using Ajax async postback to query database "chat" table. So as you can see the code portion in my Chat screen, i use updatepanel with timer trigger an async postback.
<div id="chatdisplay" class="chatdisplay">
                        <asp:Timer ID="Timer1" runat="server" Interval="2000" ontick="Timer1_Tick"></asp:Timer> 
                        <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" >
                        <Triggers>
                            <asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
                            <asp:AsyncPostBackTrigger ControlID="btnSend" EventName="Click" />
                        </Triggers>
                        <ContentTemplate>    
                        <asp:Table ID="chatPanel" runat="server" Width="100%"  CssClass="tableWidth">
                            </asp:Table>
 
                        </ContentTemplate>
                        </asp:UpdatePanel>
                    </div>

But the problem happen when i run the program,i'm not able to highlight and copy the text in the chat display,,, because the chat display is refresh every 2 second.
Cant everyone point out my mistake either in the way i implement ajax in my web chat or the concept is wrong.

Why not refresh it when a message is sent or recieved instead of being on a timer?
