Auto refresh webpage in Asp.Net c#

• You can simply add following line of code in the Header section to enable auto refresh in an ASP.NET web page.

        <meta http-equiv="refresh" content="15">

• Use JavaScript's SetTimeOut Function Like this:

        SetTimeOut(5000, window.location.reload(true);); 

• If you want to set the refresh time dynamically then that can be done in ASP.NET by adding server side code in the Page_Load function to set it, as shown below: 

        Response.AppendHeader("Refresh", "15")
