TabControl控件在左側繪制tabPage頁面

效果圖：

代碼：

1.設置控件屬性

   tabControl1.DrawMode = TabDrawMode.OwnerDrawFixed;
   tabControl1.Alignment = TabAlignment.Left;
   tabControl1.SizeMode = TabSizeMode.Fixed;
   tabControl1.Multiline = true;
   tabControl1.ItemSize = new Size(50, 100);

2.設置事件

       private void tabControl1_DrawItem(object sender, DrawItemEventArgs e)
        {
            Rectangle tabArea = tabControl1.GetTabRect(e.Index);//主要是做個轉換來獲得TAB項的RECTANGELF
            RectangleF tabTextArea = (RectangleF)(tabControl1.GetTabRect(e.Index));
            Graphics g = e.Graphics;
            StringFormat sf = new StringFormat();//封裝文本布局信息
            sf.LineAlignment = StringAlignment.Center;
            sf.Alignment = StringAlignment.Center;
            Font font = this.tabControl1.Font;
            SolidBrush brush = new SolidBrush(Color.Black);//繪制邊框的畫筆
            g.DrawString(((TabControl)(sender)).TabPages[e.Index].Text, font, brush, tabTextArea, sf);
        }
