Form1 Code:

    UserControl1 myusercontrol = new UserControl1();

    public void TabClose(Object sender,EventArgs e)
    {
        int i = 0;
        i = tabControl1.SelectedIndex;
        tabControl1.TabPages.RemoveAt(i);
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        myusercontrol.Dock = DockStyle.Fill;
        TabPage myTabPage = new TabPage();
        myTabPage.Text = "Student";
        myTabPage.Controls.Add(myusercontrol);
        tabControl1.TabPages.Add(myTabPage);
        myusercontrol.OkClick += TabClose;

    }

UserControl1 Code:

     public delegate void OkClickedHandler(Object sender, EventArgs e);

public partial class UserControl1 : UserControl
{

    public event OkClickedHandler OkClick;
    public UserControl1()
    {
        InitializeComponent();

    }


    private void button3_Click(object sender, EventArgs e)
    {
        if (OkClick == null) return;
        OkClick(sender, e);

    }
}
