Hi,

Try to this java script code:

HTML

<script type="text/javascript">
                       
 function alpha(e) 
            { 
	    var k;
            document.all ? k = e.keyCode : k = e.which;
            return ((k > 64 && k < 91) || (k > 96 && k < 123) || k == 8 || k==32 || k==13);
	    }
</script>

ASP.NET

<asp:textbox id="txtpartyhallname" runat="server" width="200px" cssclass="WaterMarkedTextBox" onkeydown="return alpha(event)" xmlns:asp="#unknown"></asp:textbox>

you just run the below code and learn

XML

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>
Registration Form
</title>
<script type="text/javascript">
function check()
{
var ck_username = /^[A-Za-z]{3,20}$/;
d=document.form;
if (document.form.username.value.search(ck_username)==-1)
{
alert("Please only enter 6 to 12 alphabets");d.username.value='';d.username.focus();return false
}
else
{
alert("username validated OK.");d.username.value='';d.username.focus();return false}
}
</script>
</head>
<body>
<form style='margin-left:340px' name='form' action=" " method="POST" onsubmit="return check()">
<INPUT maxLength="12" type="text" name="username" size="12">
<INPUT TYPE="SUBMIT" value="Submit Username">
<INPUT TYPE="RESET" value="reset">
</form>
    </body>
</html>
