C#——Tabcontrol控件选型卡在左

第一步：设置Alignment=left
              设置DrowMode=OwnerDrawFixed
              设置ItemSize=30,100
              设置SizeMode=Fixed
第二部：重绘，实现tabcontrol控件的tabControl1_DrawItem事件，如下所示
 private void tabControl1_DrawItem(object sender, DrawItemEventArgs e)
        {
            string text=((TabControl)sender).TabPages[e.Index].Text;
            SolidBrush brush=new SolidBrush(Color.Black);
           StringFormat sf = new StringFormat(StringFormatFlags.DirectionRightToLeft);
           sf.LineAlignment = StringAlignment.Center;
           sf.Alignment = StringAlignment.Center;
           e.Graphics.DrawString(text, SystemInformation.MenuFont,brush, e.Bounds, sf);
        }

        //调整选项卡文字方向
        private void tabControl1_DrawItem(object sender, DrawItemEventArgs e)
        {
            SolidBrush _Brush = new SolidBrush(Color.Black);//单色画刷
            RectangleF _TabTextArea = (RectangleF)TabControl1.GetTabRect(e.Index);//绘制区域
            StringFormat _sf = new StringFormat();//封装文本布局格式信息
            _sf.LineAlignment = StringAlignment.Center;
            _sf.Alignment = StringAlignment.Center;
            e.Graphics.DrawString(TabControl1.Controls[e.Index].Text, SystemInformation.MenuFont, _Brush, _TabTextArea,_sf);
        }

this.TabControl1.DrawItem += new System.Windows.Forms.DrawItemEventHandler(this.tabControl1_DrawItem);
