Here, we will use JavaScript to refreshing web page automatically.

Using Java Script

Add the following java script code in the head section of the page.

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm2.aspx.cs" Inherits="Textarea_count.WebForm2" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

<script type="text/JavaScript">

function RefreshPage(Period) {

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

}

</script>

</head>

<body>

<form id="form1" runat="server">

<div>

<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>

</div>

</form>

</body>

</html>

Now Drag and drop a label control on the form and add the following code on the page load event.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Label1.Text = "TimeOfDay: " & TimeOfDay().ToString()

End Sub
