How to load a form inside another form in C# 2008?

Hello,

I have 3 forms: Form1, Form2 and Form3. Form1 is the main form. We can call form from another form by using:

private void btnForm2_Click(object sender, EventArgs e)

{

    Form2 formDig1 = new Form2();

    formDig1.Show();

}

My question is: HOW TO LOAD A FORM "INSIDE" OF ANOTHER FORM? Any sample code would be helpful. Thanks.

Regards,

Srinath.
