XML

<script type ="text/javascript">
    function validate() {
var digits = "0123456789";
        var temp;
        if (document.getElementById("<%=TEXTBOXOffTel.ClientID %>").value.length > 5){
        alert("cannot be more than 5 charecters ");
                document.getElementById("<%=TEXTBOXOffTel.ClientID%>").focus();
                return false;
                }
                else {

        for (var i = 0; i < document.getElementById("<%=TEXTBOXOffTel.ClientID %>").value.length; i++) {
            temp = document.getElementById("<%=TEXTBOXOffTel.ClientID%>").value.substring(i, i + 1);
            if (digits.indexOf(temp) == -1) {
                alert("cannot be Blank or Character ");
                document.getElementById("<%=TEXTBOXOffTel.ClientID%>").focus();
                return false;
            }
            }
            }


       return true;
    }

</script>

Same you can do with the other textbox

Try this:

C#

function isNumberKey(evt, obj) 
         {
            var LIMIT = 5;
            var charCode = (evt.which) ? evt.which : event.keyCode
            var txt = obj.value.length;
            if ((txt == LIMIT) && (charCode == 8)) {
                obj.value = obj.value.toString().substring(0, txt-1);
            }
            if (charCode > 31 && (charCode < 48 || charCode > 57))
                return false;
            else {
                if (txt < LIMIT) {
                    return true;
                }
                else {
                    return false;
                }
            }
        }

Hi....

u can set maxlength of ur textboxes as 5 & 4 respectively, and use these validators:

XML

<asp:RangeValidator ID="cvTEXTBOXOffTel" runat="server" ControlToValidate="TEXTBOXOffTel" Type="Integer" MinimumValue="0" MaximumValue="99999" />
    <asp:RangeValidator ID="cvTEXTBOXextension" runat="server" ControlToValidate="TEXTBOXextension" Type="Integer" MinimumValue="0" MaximumValue="9999" />

Hi
Try like this

C#

bool Valid = false;

C#

private void button1_Click(object sender, EventArgs e)
        {

            Regex rx = new Regex("^[0-9]*$");
            if (!string.IsNullOrEmpty(TxtTelphone.Text))
            {
                if (rx.IsMatch(TxtTelphone.Text))
                {
                    Valid = true;
                }
                else
                {
                    MessageBox.Show("characters not allowed.");
                    TxtTelphone.Clear();
                    TxtTelphone.Focus();
                    return;
                }
            }
            else
            {
           MessageBox.Show("Please enter a Telphone no and click Ok.");
                TxtTelphone.Focus();
                return;
            }
        }

And allow only for 5 digits use this code

C#

private void TxtTelphone_KeyPress(object sender, KeyPressEventArgs e)
        {
           //You may make it 4 or 5 depends on your application
           if (TxtTelphone.Text.IndexOf(' ') == TxtTelphone.Text.Length - 6)
                    e.Handled = true;
        }
