hi vijay if you need to postback your page you just add return true in your javascript function after alert it will postaback your page

<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title></title>
<script type="text/javascript">
function done() {

alert('hi');
return true;
}
</script>
</head>
<body>
<form id="form1" runat="server">
<asp:Button ID="Button1" runat="server" Text="Button" CssClass="cssbutton" OnClientClick="return done()" />
</form>
</body>
</html>
