You will find some good options here:
jQuery: what is the best way to restrict “number”-only input for textboxes?[^]
EDIT:
Code Example
I do some code like you applied there and find it is working good for 2 textboxes that accepts only 6 digit numbers, hope it would be helpful for you. See:

JavaScript

<script type="text/javascript">
    function isNumberKey(evt) {
        var charCode = (evt.which) ? evt.which : event.keyCode;
        if (charCode != 46 && charCode > 31 && (charCode < 48 || charCode > 57)) {
            return false;
        } else {
            return true;
        }
    }
</script>

ASP

<asp:TextBox ID="TextBox1" runat="server" MaxLength="6" onkeypress="return isNumberKey(event)"></asp:TextBox>
<asp:TextBox ID="TextBox2" runat="server" MaxLength="6" onkeypress="return isNumberKey(event)"></asp:TextBox>

I tried like this : Added class to both the textbox (test)

<asp:TemplateField HeaderText="Approved Km By Ops">
<itemtemplate>
<asp:TextBox ID="txtdistanceops" MaxLength="6" class="test" CssClass="textBox_for6tds" runat="server"
Text='<%#Bind("distanceByOps") %>'>

<itemstyle horizontalalign="center">

<asp:TemplateField HeaderText="Approved Km By CTV" Visible="false">
<itemtemplate>
<asp:TextBox ID="txtdistancectv" MaxLength="6" class="test" CssClass="textBox_for6tds" runat="server">

<itemstyle horizontalalign="center">

---then i tried in this way....not working
<script type="text/javascript">
$(function() {
$('.test').keydown(function(e) {
if (e.shiftKey || e.ctrlKey || e.altKey) {
e.preventDefault();
} else {
var key = e.keyCode;
if (!((key == 8) || (key == 46) || (key >= 35 && key <= 40) || (key >= 48 && key <= 57) || (key >= 96 && key <= 105)))
{
e.preventDefault();
alert("Please enter numeric value!");
$('[id*=txtdistanceops]').val('');

}
}
});
});
