ListBox 项的背景颜色(Windows 窗体) [英] Background color of a ListBox item (Windows Forms)

问题描述

如何在 System.Windows.Forms.ListBox 中设置特定项目的背景颜色?

How can I set the background color of a specific item in a System.Windows.Forms.ListBox?

如果可能，我希望能够设置多个.

I would like to be able to set multiple ones if possible.

推荐答案

可能实现这一目标的唯一方法就是自己绘制项目.

Probably the only way to accomplish that is to draw the items yourself.

将 DrawMode 设置为 OwnerDrawFixed 并在 DrawItem 事件上编写如下代码:

Set the DrawMode to OwnerDrawFixed and code something like this on the DrawItem event:

private void listBox_DrawItem(object sender, DrawItemEventArgs e)
{
    e.DrawBackground();
    Graphics g = e.Graphics;

    g.FillRectangle(new SolidBrush(Color.Silver), e.Bounds);

    // Print text

    e.DrawFocusRectangle();
}

第二个选项是使用 ListView，尽管它们有另一种实现方式(不是真正的数据绑定，但在列的方式上更灵活).

The second option would be using a ListView, although they have an other way of implementations (not really data bound, but more flexible in way of columns).
