Your code works fine, it seems it is a designing issue and the TabControl is not visible for some reason.

Try adding a Panel through the designer and then replace:

this.Controls.Add(dynamicTab);

With:

somePanel.Controls.Add(dynamicTab);

If you want to create another Page:

private void button1_Click(object sender, EventArgs e)
{
    CreatePageGrid(qsreach.ToList(), "Page 1");
    CreatePageGrid(qsreach2.ToList(), "Page 2");
    CreatePageGrid(qsreach3.ToList(), "Page 3");
}

TabControl dynamicTab;

private void CreatePageGrid(object dataSource, string pageName)
{
    if (dynamicTab == null)
    {
        dynamicTab = new TabControl();
        this.Controls.Add(dynamicTab);
    }

    DataGridView dvg = new DataGridView();
    TabPage t2 = new TabPage();
    dvg.DataSource = dataSource;
    t2.Text = pageName;
    t2.Controls.Add(dvg);
    dynamicTab.Controls.Add(t2);
}
