Adding a form to a splitcontainer from a child form

Question

I'm trying to add a form to a SplitContainer from a child form. I can do it from the forms parent using this.

Lockdown.MainForm form = new Lockdown.MainForm(true);
form.MdiParent = this;
form.TopLevel = false;
form.Dock = DockStyle.Fill;
this.splitContainer.Panel2.Controls.Add(form);
form.Show();

But I can't figure out how to do it from a child of the parent form. Any help is appreciated.

Answer 1

Here's how I solved the problem. I passed a reference to the child form.

        MessageBoxRegister register = new MessageBoxRegister(this);
        register.ShowDialog();

I then saved the reference in a global variable.

    Launcher launcher;
    public MessageBoxRegister(Launcher launcher)
    {
        InitializeComponent();

        this.launcher = launcher;
    }

Then I could open the form into the splitContainer like this.

            Lockdown.MainForm form = new Lockdown.MainForm(true);
            form.MdiParent = launcher;
            form.TopLevel = false;
            form.Dock = DockStyle.Fill;
            launcher.splitContainer.Panel2.Controls.Add(form);
            form.Show();
