ASP.NET - Cómo puedo validar un textbox para que no me deje introducir mayor a 100 en asp.net?.

<%= Html.TextBox("nota" + cont, item.nota, new { @class = "form-control", type = "number", min = "0", max = "100", id = "txtNota", placeholder = "0" , onkeypress = "ValidarNumero(event)"})%>

<script type="text/javascript">

 document.addEventListener('keypress', ValidarNumero);

    function ValidarNumero(numero) {

    if ((event.keyCode < 100) || (event.keyCode > 0))

       event.returnValue = true;

    else

       event.returnValue = false;

 }

</script>

// Aceptar solo numeros

$('.number_only').keypress(function (e) {

    return isNumbers(e, this);

});

// verificar si son numeros

function isNumbers(evt, element) {

    var charCode = (evt.which) ? evt.which : event.keyCode;

    if ((charCode != 46 || $(element).val().indexOf('.') != -1) &&      // “.” CHECK DOT, AND ONLY ONE.

                           (charCode < 48 || charCode > 57))

        return false;

    return true;

}
