Hi Emmanuel,

Base on my undertanding, you want to make the form which is opened from an
MDI child form only modal to this MDI child form. If I'm off base, please
feel free to correct me.

Firstly, the 'modal' here isn't the real modal which will block the entire
application. So we couldn't call the ShowDialog method of the form to open
it. Intead, we should add some code to imitate the 'modal' behavior.

I have replied to a post asking a similar question before. You could visit
it at the following link.

i-modal&rnum=1#b8684a1e05510189

Hope this helps.
If you have anything unclear or my workaround isn't what you want, please
feel free to let me know.

Sincerely,
Linda Liu
