C# MDI Parent detect when MDI Child is closing?

Question

I\'m attempting to detect, on the MDI parent, when my MDI child form closes, and react accordingly. The MDI parent shouldn\'t do anything until the MDI child closes. Here is

Answer 1

On mdiparent make a public function

public void MakeMenuVisible()
{
MainMenu.visible = true;
}

Then on childform you can run the function like this

private void ChildForm_FormClosed(object sender, FormClosedEventArgs e)
{
//Cast MdiParent to Mainform
((mainform)this.MdiParent).MakeMenuVisible();  
}
