As @jenson-button-event mentioned you can access the TextBox values through Request.Form here's an example:

ASPX:

Code behind:

    protected void Add(object sender, EventArgs e)
    {
        int numOfTxt = Convert.ToInt32(ddlTextBoxes.SelectedItem.Value);
        var table = new Table();

        for (int i = 0; i < numOfTxt; i++)
        {
            var row = new TableRow();
            var cell = new TableCell();

            TextBox textbox = new TextBox();
            textbox.ID = "Textbox" + i;
            textbox.Width = new Unit(180);

            cell.Controls.Add(textbox);
            row.Cells.Add(cell);
            table.Rows.Add(row);
        }

        container.Controls.AddAt(0,table);
        container.Visible = true;
    }

    protected void Submit(object sender, EventArgs e)
    {
        var textboxValues = new List();
        if (Request.Form.HasKeys())
        {
            Request.Form.AllKeys.Where(i => i.Contains("Textbox")).ToList().ForEach(i =>
                {
                    textboxValues.Add(Request.Form[i]);
                });
        }

        //Do something with the textbox values
        textboxValues.ForEach(i => Response.Write(i + "
"));
        container.Visible = false;
    }
