How can I open a child window and block the parent window only?

Question

So that, the other forms/windows in the application can still work.

Answer 1

What about disabling the parent form while the child form is active? When the child form is created, set its owner to this:

ChildForm child = new ChildForm();
child.Owner = this;
child.Show();

In ChildForm_Load:
private void ChildForm_Load(object sender, EventArgs e) {
  this.Owner.Enabled = false;
}

private void ChildForm_Closed(object sender, EventArgs e) {
  this.Owner.Enabled = true;
}

Answer 2

WinXP
VS2008 sp 3.5
C#

I was having a similar issue, and the code above helped me. The one problem I am still having is that the child window does not center in the parent window???? I went in VS and changed the Start Position of the Child form to Center Parent, but that does not work either. It will go to the upper left corner.

I would like the child window to stay inbounds of the parent bounds.

Any suggestions on how to accomplish?
