How do I add this panels to tabcontrol instead of adding them to the form?

Here is the code. Help will be much obliged. I want the panels to be added to tabePage1, but it is being added to the form instead. 

private void tabPage1_Click(object sender, EventArgs e)
{
    int i, j;
    for (i = 1; i <= 3; i++)
    {
        for (j = 1; j <= 4; j++)
        {
            Panel a = new Panel();
            a.Location = new Point(i * 200, j * 50);
            a.Width = 180;
            a.Height = 40;
            a.Name = "Rom " + (((i * 4) - 3) + (j - 1));
            a.BackColor = Color.Yellow;
            a.AllowDrop = true;
            a.DragDrop += new System.Windows.Forms.DragEventHandler(this.panel1_DragDrop);
            a.DragOver += new System.Windows.Forms.DragEventHandler(this.panel1_DragOver);
            a.Visible = true;
            Label l = new Label();
            l.Location = new Point(10, 10);
            l.Width = 180;
            l.Text = a.Name;
            a.Controls.Add(l);
            l.AllowDrop = true;
            this.Controls.Add(a);

This code:

this.Controls.Add(a);

adds the control to the Form, because your tabPage1_Click method is in a subclass of Form (making this refer to the Form). To add the panels to tabPage1, do this instead:

tabPage1.Controls.Add(a);

Incidentally, do you really want to add all the panels to a single TabPage, or do you want to create a TabPage for each panel? If the latter, the code will obviously look different.

Edit: in answer to your comment, you can add to a different TabPage by referring to it by name as above (e.g. tabPage2.Controls.Add(a);) or, if you want to add a set of panels to each TabPage in your TabControl, you could do something like this:

foreach (TabPage tp in yourTabControl.TabPages)
{
    // create panel...
    tp.Controls.Add(a);
    // ...
}
