我会让ListBox所有者的DrawMode绘制并为ListBox添加一个DrawItem事件。 http中有一个示例：//msdn2.microsoft.com/en-us/lib....drawmode.aspx 。您只需将switch语句替换为如果大则使用红色画笔的逻辑。 HTH --Sam

I would make the DrawMode of the ListBox owner draw and add a DrawItem event for the ListBox. There is an example at http://msdn2.microsoft.com/en-us/lib....drawmode.aspx. You would just replace the switch statement with logic that says if big then use the red brush. HTH --Sam

嗨Sam，

对于我现在的愚蠢问题。如何将DrawItem事件添加到列表框？ :(

我只设法将DrawMode更改为OwnerDraw。


还有一件我不明白的是如何得到这个：
private void listBox1_DrawItem（object sender，System.Windows.Forms.DrawItemEventArgs e）


当我双击我的UI（列表框）时。它返回：
private void lstFiles_SelectedIndexChanged（object sender，EventArgs e）


我在这方面很新...请耐心等待对我很感激并感谢你的指导。

Hi Sam,
For the dumb question I have now. How to add the DrawItem event to the listbox? :(
I only managed to change the DrawMode to OwnerDraw.

And one more thing that i don''t understand is how to get this:
private void listBox1_DrawItem(object sender, System.Windows.Forms.DrawItemEventArgs e)

When I double-click on my UI (listbox). it returns this:
private void lstFiles_SelectedIndexChanged(object sender, EventArgs e)

I am very new in this area... Please be patient to me and thanks a lot for your guidance.

我还有一件事我不明白如何得到这个：
私有无效listBox1_DrawItem（对象发送者，System.Windows.Forms.DrawItemEventArgs e）


当我双击我的UI（列表框它返回：
私有空lstFiles_SelectedIndexChanged（对象发送者，EventArgs e）

没问题，我们会非常慢。

No problem, we''ll go very slow.

1. 打开一个新的C＃Windows应用程序并向表单添加ListBox
2. 双击表单以生成加载事件。添加一些代码将东西放入ListBox：

展开 | 选择 | Wrap | 行号
