    Define control visibility

    Hello,

    What is the difference of adding a control to a page and setting its
    visible property to false or not adding it?

    Is it not the same in terms of the generated layout?

    I suppose the difference is that the added control is added to the
    viewstate even if invisible. Is this right?

    Thanks,

    Miguel

      Hi,

      non-visible control exists fully at server-side, it just doesn't participate
      in rendering. Not adding a control means that control doesn't exist at all
      as it doesn't participate control lifecycle etc etc
