Now design your aspx page like this

<script type="text/javascript">
function setHeight(txtdesc) {
txtdesc.style.height = txtdesc.scrollHeight + "px";
}
</script>
</head>
<body>
<form id="form1" runat="server">
<asp:TextBox ID="txtDesc" runat= "server" TextMode="MultiLine" onkeyup="setHeight(this);" onkeydown="setHeight(this);" />
</form>
</body>
</html>
