Enabled during defition

[l3whmg]

Hi guys,
I don't remember and I don't find (and I think there is'nt the ability) to disable controls (ex. TEXTBOX) during form/control definition (I'm speaking about HMG3). Of course, I can can use "formname.ctrlname.Enabled := ...", but it's not the same what I want...
For example: when I show a form for the first time, header (do you think about user must enter a code) is enabled and details (do you think about user enter many data regarding code) are disabled; when user enter a valid header than can manage detail: at this moment details are enabled and code disabled.

Any suggestion?
