Here is the code:
I am Creating Tabs Dynamically.

private void AddFieldsInsideTab()
{
    for (int i = 0; i < 4; i++)
    {
        Table tbGrid = new Table();
        TableRow trGrid = new TableRow();
        TableCell tcGrid = new TableCell();

        TextBox txtB = new TextBox();
        txtB.ID = "txtB" + i;

        tcGrid.Controls.Add(txtB);

        Button btnShowText = new Button();
        btnShowText.Text = "Show Text" + i;
        btnShowText.ID = "btn" + i;
        btnShowText.Click += new EventHandler(btnShowText_Click);

        tcGrid.Controls.Add(btnShowText);

        trGrid.Cells.Add(tcGrid);
        tbGrid.Rows.Add(trGrid);
        tbcDynamic.Tabs[i].Controls.Add(tbGrid);
    }
    PlaceHolder1.Controls.Add(tbcDynamic);
}

void btnShowText_Click(object sender, EventArgs e)
{
    //throw new NotImplementedException();
    TextBox txt = (TextBox)(tbcDynamic.ActiveTab.FindControl("txtB" + tbcDynamic.ActiveTabIndex));
    lblMessage.Text = txt.Text;
    //Response.Write(txt.Text);
}

protected void Page_Init(object sender, EventArgs e)
{
    try
    {
        createTab();
    }
    catch (Exception ex)
    {
        // lblError.Text = ex.Message;
    }
}

private void createTab()
{
    tbcDynamic = new TabContainer();
    tbcDynamic.Width = 500;

    for (int i = 0; i < 4; i++)
    {
        TabPanel Panel1 = new TabPanel();
        Panel1.HeaderText = "New Tab" + i;
        Panel1.ID = "Tab" + i.ToString();
        tbcDynamic.Tabs.Add(Panel1);
    }
}
