   i have a grid add form which gets first and last name  and a grid which shows full name
   i have a hidden field asrt_speakerfullname_0 on the form and a function
   
   $(document).on("tpc:pre-submit", function (event, form, formData, sender) {
           tpc.page.asrt_speakerfullname_0.set_value(tpc.page.asrt_firstname.get_value()+" "+tpc.page.asrt_lastname.get_value());
   });
   
   when I try to read the value of asrt_speakerfullname_0 in the grid  the full name is coming as null. what am I doing wrong?

   hi Krishna
   
   You may need to register for a Q+A for this. If speakerfullname is a text field, then it's possible that it's readonly. I would suggest you reveal it on your page for testing purposes and see if you can use change its value by using the code that is inside your tpc:pre-submit.

   Hi Krishna,
   
   The event you are looking for that will allow the values to be changes is the "tpc:pre-validate" event. This is the first event to fire and is the only one that will allow the data in the fields to be changed before submission. All other events fire after the contents have been checked to see if they have changed, i.e, are "dirty".  Once that happens, nothing can be changed.
   
   Hopefully this information is helpful.
