For HH:mm format in Textbox you have to mask the textbox


<pre lang="HTML">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript" src="jquery.maskedinput.js"></script>
</head>
<body>
<form id="form1" runat="server">
<asp:textbox runat="server" id="txt1" text="99:99" xmlns:asp="#unknown">
</form>
</body>
<script type="text/javascript">
$(function () {

$("#txt1").mask("99:99");
});
</script>
</html>
