Hi experts.

i have got a text box it should allow only numbers and comma(,)

Presently am using this java script to validate the textbox

C#

function isInteger(evt)
      {
         var charCode = (evt.which) ? evt.which : event.keyCode
         if (charCode > 31 && (charCode < 48 || charCode > 57))
             return false;
         return true;
     }

but if i copy some text and paste in the textbox, this type of validation will not work

can any one please help me to solve this issue?

thanks in advance
