How to render a hidden field?

[Eric Caron]

Hi all,

I am trying to display a hidden field in my form that will contain the id of
the record I am editing. How can I do that using the controls in the
toolbox of VB.NET? I tried using a textbox and a label with their Visible
property set to true, but it just doesn't display anything in the source of
the rendered page. I could write the hidden field directly in HTML, but I'd
like to fill the all fields in my Page_Load event to keep things clean.

TIA!
