hi, keep looking in old posts within this group. It has come up on various
occassions and you will find some very good answers. Basically as a rule of
thumb, keep in mind that any controls you add to the webform dynamically
need to be reloaded manually by yourself(the same way it was loaded the last
time) after a postback scenario.

Have a good day,
