首页添加选卡的方法：

        public void tabControlAdd(string tabName, string tabText, object flag, Form ctl)
        {
            bool bl = true;
            foreach (XtraTabPage tbl in xtraTabControl1.TabPages)
            {
                if (tbl.Name == "tab_" + tabName + flag.ToString())
                {
                    xtraTabControl1.SelectedTabPage = tbl;
                    bl = false;
                    break;
                }
            }
            if (bl == true)
            {
                ctl.Name = tabName + flag.ToString();
                ctl.Text = tabText;
                ctl.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None; //设置窗体为非边框样式           
                ctl.Dock = System.Windows.Forms.DockStyle.Fill; //设置样式是否填充整个panel               
                ctl.Tag = flag; 
                //-------------------------------------
                XtraTabPage tb = new XtraTabPage();
                tb.Name = "tab_" + tabName + flag.ToString();
                tb.Text = tabText;
                tb.Dock = System.Windows.Forms.DockStyle.Fill; //设置样式是否填充整个panel                    
                //--------------------------------------------------------               
                xtraTabControl1.TabPages.Add(tb);
                xtraTabControl1.SelectedTabPage = tb;//显示该页
                //-------------------------------------------                   
                ctl.TopLevel = false;      //设置为非顶级窗体  
                tb.Controls.Add(ctl); //页面添加 容器
                ctl.Show();                
            }
        }

ProgressBar美化

 class MyProgressBar:ProgressBar //新建一个MyProgressBar类，它继承了ProgressBar的所有属性与方法
    {
        public MyProgressBar()
        {
            base.SetStyle(ControlStyles.UserPaint, true);//使控件可由用户自由重绘
        }
        protected override void OnPaint(PaintEventArgs e)
        {
            SolidBrush brush = null;
            Rectangle bounds = new Rectangle(0, 0, base.Width, base.Height);
            e.Graphics.FillRectangle(new SolidBrush(this.BackColor), 1, 1, bounds.Width - 2, bounds.Height - 2);//此处完成背景重绘，并且按照属性中的BackColor设置背景色
            bounds.Height -= 4;
            bounds.Width = ((int)(bounds.Width * (((double)base.Value) / ((double)base.Maximum)))) - 4;//是的进度条跟着ProgressBar.Value值变化
            brush = new SolidBrush(this.ForeColor);
            e.Graphics.FillRectangle(brush, 2, 2, bounds.Width, bounds.Height);//此处完成前景重绘，依旧按照Progressbar的属性设置前景色
        }
    }

　完成以上步骤之后，我们如何在界面中插入自己的进度条呢？``我们可以先插入一个winform自带的ProgressBar，调整好位置，ForeColor，BackColor属性，然后进入窗体的Designer程序中做如下修改：

//private System.Windows.Forms.ProgressBar progressBar1;//注释此句
private MyProgressBar progressBar1; //新添此句，添加新的控件MyProgressBar
private void InitializeComponent()
{
    //this.progressBar1 = new System.Windows.Forms.ProgressBar();//注释此句
    this.progressBar1 = new 界面美化.MyProgressBar();//新添此句，此处对MyPorgressBar实例化
    this.SuspendLayout();
    this.progressBar1.Location = new System.Drawing.Point(137, 68);
    this.progressBar1.Name = "progressBar1";
    this.progressBar1.Size = new System.Drawing.Size(100, 23);
    this.progressBar1.TabIndex = 0;
}
