Hi,

Could you explain what is the next section i.e. is it control or page?

Also to avoid post back you can use asp.net ajax update panel for the control causing a postback.

One is Javascript

setTimeout("location.reload(true);", timeout);

The second is a Meta tag:

<meta http-equiv="refresh" content="600">

You can set the refresh intervals on the server side.



or




To refresh web page after some time period you can use HTML meta tag. This line placed inside of <head > tag will refresh web page every 10 seconds:

<head>
<title>Untitled Page</title>
<meta http-equiv="refresh" content="10">
</head>



You can implement this dynamically too. Let say that this refresh period is not constant and you need to be able to change it in settings area of your ASP.NET application. You can achieve this if you set ID parameter and add runat="server" part, like this:

<meta id="RefreshPeriod" runat="server" http-equiv="refresh" content="10" />



After that, in code behind you can manipulate with refresh period. Let say you want to refresh page every 5 seconds:

[ C# ]

public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
// Set refresh period in seconds
RefreshPeriod.Content = "5";
}
}

Thanks And Regards.
