MDI Forms and Children

Hi there

Say you have a main form with one or more toolstrips and you are adding an MDI child as follows (in MDI parent)

frmChild frm = new frmChild();
frm.TopLevel = false;
frm.Parent = this;
frm.Show();

In this case the child form appears underneath my toolstrip.

Is there a simple way to prevent this?

Solution 1

Why are you setting TopLevel to false? That might be your problem.

EDIT ===============

If whoever is voting answers a 1 is going to do that, at least be a man and say why. If my answer is wrong, I'll delete it, but you have to prove to me it's wrong first.

Top Level to false making it hidden behind other forms. So, remove that statement. It will definitely work.

You should set MdiParent, not Parent.

Do you want a better advice? Don't torture yourself and never scare off your users: never use MDI.

I see your point about MDI. I got rid of MDI because it was a pain in the a**.

Right, and the worst thing is that it makes using application very inconvenient. Simple TabControl-based interface is much better; there are many other good variants with just one main application window.
Thank you,
