Although not 100%, this code may help you.

public partial class MDIForm : Form
    {
        public string Message
        {
            get { return this.textBox1.Text; }
            set { this.textBox1.Text = value; }
        }
 
        public MDIForm()
        {
            InitializeComponent();
        }
 
        int cout = 0;
        private void btnCreateChild_Click(object sender, EventArgs e)
        {
            ChildForm f = new ChildForm(cout.ToString());
            f.MdiParent = this;
            f.Show();
            ++cout;
        }
    }
public partial class ChildForm : Form
    {
        public ChildForm(string name)
        {
            InitializeComponent();
            this.Text = name;
        }
 
        private void ChildForm_FormClosing(object sender, FormClosingEventArgs e)
        {
            MDIForm f = this.ParentForm as MDIForm;
 
            if (f != null)
            {
                f.Message = "Child " + this.Text + " is just closed";
            }
        }
    }
 
static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new MDIForm());
        }
    }

Thx, I solve this yesterday.

I solve it another way.

public void MDI_Child_closing(string strID)
{
any action
}
 
private void TestChild_FormClosing(object sender, FormClosingEventArgs e)
{
((Form1)this.MdiParent).MDI_Child_closing(this.Text);
}
