The timer control to implement no refresh, the use of Ajax technology, we can use VS2008 Ajax technology. The first thing you need to do is add a ScriptManager control, and then add a UpdatePanel to hold the contents of the Timer control, and you can implement no refresh. Here's what it's all about:

First, the front desk:

 <form id= "Form1" runat= "Server";
    
    <asp: ScriptManager id= "ScriptManager1" runat= "Server",
    </asp:scriptmanager>
     
    
             <asp:updatepanel id= "UpdatePanel1" runat= "Server";
             <contenttemplate>
                 <asp:timer id= "Timer1" runat= "Server" interval= "60000" ontick= "Timer1_Tick"
                </asp: Timer>
            </contenttemplate>
            </asp:UpdatePanel>

</form>

Remember ScriptManager must be placed in the <form> tag, can be placed in any place. After adding the UpdatePanel control, it is necessary to use a very important property contenttemplate, otherwise it will not be able to achieve no refresh effect. Here we set the 6-second timer to trigger the event once.

Second, backstage code

protected void Page_Load (object sender, EventArgs e)
{}

protected void Timer1_Tick (object sender, EventArgs e)
{

Here you can do what you want to do, such as querying the database regularly

Scriptmanager.registerstartupscript (this, this.) GetType (), "", "alert (' Hello ');", true);

}

Here I implement the content of the dialog hello that pops up every 6 seconds.
