Winform界面处理技巧

winform combobox数据绑定

comboxDevice.DataSource = ProductionLine.DeviceInit();
            comboxDevice.DisplayMember = "device_nm";
            comboxDevice.ValueMember = "device_type";

//get text
comboxDevice.Text;
(comboxDevice.SelectedItem as ProductionLine).device_nm;

//get value
comboxDevice.SelectedValue

　　

tabControl选项卡外观美化

默认的看上去比较素，选项卡标签加图片，但没有这个属性方法可改，通用绘制实现

//修改以下设计时属性
tabControl1.DrawMode =OwnerDrawFixed; //自绘制模式
tabControl1.SizeMode =Fixed; //tab宽度固定，默认太小，字显示不全
tabControl1.ItemSize = Size(120, 25);//tab大小

//在drawItem事件绘制tab
private void tabControl1_DrawItem(object sender, DrawItemEventArgs e)
        {
            Rectangle Rect = tabControl1.GetTabRect(e.Index);

            if (e.Index == tabControl1.SelectedIndex)
                e.Graphics.DrawString("测试结果", new Font(this.Font, FontStyle.Bold), Brushes.Black, Rect.Left + 30, Rect.Top + 3);
            else
                e.Graphics.DrawString("测试结果", this.Font, Brushes.Black, Rect.Left + 30, Rect.Top + 3);

            Image image = imageList1.Images[e.Index];
            e.Graphics.DrawImage(image, new Rectangle(Rect.X+6, Rect.Y+3, image.Width, image.Height));
           
        }
