Answer 1

Hello. This is not possible directly indeed. If you are using Web Forms you can have a C# button handler which will change text of your label in server side and then you can call the _doPostBack function for that handler.

Somehow you have to do as postback, either complete or partial. Use AJAX (UpdatePanel)
