  I solved it Here is the solution

  <script language="javascript" type="text/javascript">
  
          function onlyNumbers(evt) {
  
              evt = (evt) ? evt : window.event;
              var charCode = (evt.which) ? evt.which : evt.keyCode;
              if (charCode > 31 && (charCode < 48 || charCode > 57)) {
                  status = "This field accepts numbers only.";
                  alert("This field accepts numbers only.");
                  return false;
              }
              status = "";
              return true;
          }   
  
      </script>

  tb.Attributes.Add("onkeypress", "return onlyNumbers(event);");

  where tb is the dynamic textbox control
