You can use below code to make textbox accepts only alphabets
<script>
     $(document).ready(function() {
       //Attach key press event to textbox
       $("#Textbox1").keypress(function(e) {
         //Get the key code
         var key = e.keyCode;
         if (key >= 48 && key <= 57) {
           e.preventDefault();
         }
       });
     });
