Hey friend,


Let me explian you about it with an example.


Let's say you have a form called Form1. That's your main form.


You have a menustrip in that main form  and you have added a menustrip item to the menustrip. When you click on the menustrip item, it creates another form inside the main from.



To do this, you should write your code as follows.



In your main form's constructor you should add this red line.

 

public Form1()
        {
            InitializeComponent();
            this.IsMdiContainer = true;
        }



Then you should wrtie following code in the click event of menu strip item.



        private void toolStripMenuItem1_Click(object sender, EventArgs e)
        {
            Form childform = new Form();
            childform.MdiParent = this;//here, 'this' is Form1
            childform.Show();
        }


That's all you have to do.

Check it and let me know.
