Auto refresh in ASP.NET MVC

In webforms I'd do

    <script type="text/JavaScript">
    function timedRefresh(timeoutPeriod) {
        setTimeout("location.reload(true);", timeoutPeriod);
    }
    </script>

    <body onload="JavaScript:timedRefresh(5000);">

or codebehind Page_Load

Response.AddHeader("Refresh", "5");

Question How to make the screen refresh every 5 seconds in ASP.NET MVC3

Solution

  • You could do the same in MVC:

    <script type="text/javascript">
function timedRefresh(timeoutPeriod) {
    setTimeout(function() {
        location.reload(true);
    }, timeoutPeriod);
}
</script>
<body onload="JavaScript:timedRefresh(5000);">
    ...
</body>

    or using a meta tag:

    <head>
    <title></title>
    <meta http-equiv="refresh" content="5" />
</head>
<body>
    ...
</body>

    or in your controller action:

    public ActionResult Index()
{
    Response.AddHeader("Refresh", "5");
    return View();
}
