   Hi Arun,
   In your code doesnot allows the back space key.So i rewrite the code as follows
   function IsNumeric(event)
   {
   var unicode=event.keyCode? event.keyCode: event.charCode;
   if ((unicode 33)&&(unicode 57) )
   {
   if(unicode==8)
   {
   return true;
   }
   return false;
   }
   return true;
   }

   Thanks
