Usercontrol open mdichild?

[Kate Giacomozzi]

I am bulding a Windows Form Application in Visual Studio using C#.

In my application the main form (form1) has a usercontrol with a button. When the user clicks the button I would like a MdiChild form (of form1) to appear.

Normally when opening a MdiChild from a button on a parent form or another child form I use:

private void Button1_Click(object sender, EventArgs e)
 {
 
Form2 newMdiChild = new Form2();
 newMdiChild.Mdiparent = this.Mdiparent;
 newMdiChild.Show();

However, this does not work with the Usercontrol button due to an error that states the Usercontrol does not contain a definition for MdiParent.

I am still new to programming but any help would be greatly appreciated.

create 3 Forms: Form1, Form2 and Form3.

Form1:

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            this.IsMdiContainer = true;
        }

        private void button1_Click(object sender, EventArgs e)
        {
            Form2 f2 = new Form2();
            f2.MdiParent = this;
            f2.Show();
        }

        private void button2_Click(object sender, EventArgs e)
        {
            Form3 f3 = new Form3();
            f3.MdiParent = this;
            f3.Show();
        }
    }
}

Form2:

namespace WindowsFormsApplication1
{
    public partial class Form2 : Form
    {
        public Form2()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            Form2 f2 = new Form2();
            f2.MdiParent = this.MdiParent;
            f2.Show();
        }

        private void button2_Click(object sender, EventArgs e)
        {
            Form3 f3 = new Form3();
            f3.MdiParent = this.MdiParent;
            f3.Show();
        }
    }
}

Form3:

namespace WindowsFormsApplication1
{
    public partial class Form3 : Form
    {
        public Form3()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            Form3 f3 = new Form3();
            f3.MdiParent = this.MdiParent;
            f3.Show();
        }

        private void button2_Click(object sender, EventArgs e)
        {
            Form2 f2 = new Form2();
            f2.MdiParent = this.MdiParent;
            f2.Show();
        }
    }
}
