I have dynamically created textboxex,in which I would like to enter only numbers.This works fine.I would like to paste only numbers.This works in internet explorer .But in firefox i am able to paste text also.  I have used the following code

in C#
tb.Attributes.Add("onpaste", "return alloNumbersOnly(this);");//paste only nembers

in aspx

<script type="text/javascript">
      function alloNumbersOnly(obj) {
          var txt = window.clipboardData.getData('Text');
          if (isNaN(txt)) {
              alert('Please paste only numbers!');
              return false;
          }
      }
    </script>

How can I make this function work in firefox also ?

Or try with onchange event , There is no onpaste event for Firefox .. ofcourse, onchange will fire not only for pasting..
