WinForm中ListBox的使用

• 获取选中数据：listbox.SelectedItem as XXX
• 重绘每一行item
  • DrawMode设置为DrawMode.OwnerDrawVariable
  • 然后实现DrawItem(object sender, DrawItemEventArgs e)
  • 重绘选中行（鼠标所在行），如修改选中行的背景色

    •              if ((e.State & DrawItemState.Selected) == DrawItemState.Selected)
                   {
                       e = new DrawItemEventArgs(e.Graphics,
                                         e.Font,
                                         e.Bounds,
                                         e.Index,
                                         e.State ^ DrawItemState.Selected,
                                         e.ForeColor,
                                         DataSourceUIParams.TableRowBackColorWhenHover);
                   }
      
                   e.DrawBackground();

  • 重绘所有行
