Solution 1

user below javascript function:-

C#

// To accept only character  and spaces.
function IsCharacterKeyCheck(event)
{
    var charCode = (event.which) ? event.which : event.keyCode;
    if (charCode >= 65 && charCode <= 90 || charCode >= 97 && charCode <= 122 || charCode == 8 || charCode == 32)
    return true;
    return false;
}

and add

onkeypress="return IsCharacterKeyCheck(event)"

in your asp:button.

On top of Trushnak solution..
Try this using jquery

XML

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <script src="jquery-1.10.2.js" type="text/javascript"></script>
    <script type="text/javascript">

        $(function () {

            $('#txt').keydown(function (event) {
                var charCode = (event.which) ? event.which : event.keyCode;
                var isvalid = charCode >= 65 && charCode <= 90 || charCode >= 97 && charCode <= 122 || charCode == 8 || charCode == 32;
                if (!isvalid)
                    event.preventDefault();

            });

        });

    </script>
</head>
<body>
    <form id="form1" runat="server">
    <asp:TextBox ID="txt" runat="server"></asp:TextBox>
    </form>
</body>
</html>
