如何使 ListBox 中的某些项目变为粗体? [英] How can I make some items in a ListBox bold?

问题描述

在 Visual c# Express Edition 中，是否可以将 ListBox 中的某些(但不是全部)项目设为粗体?我在 API 中找不到任何类型的选项.

In Visual c# Express Edition, is it possible to make some (but not all) items in a ListBox bold? I can't find any sort of option for this in the API.

推荐答案

需要将listbox的DrawMode改为DrawMode.OwnerDrawFixed.查看 msdn 上的这些文章:
DrawMode 枚举
ListBox.DrawItem 事件
Graphics.DrawString 方法

You need to change listbox's DrawMode to DrawMode.OwnerDrawFixed. Check out these articles on msdn:
DrawMode Enumeration
ListBox.DrawItem Event
Graphics.DrawString Method

在msdn论坛上也看看这个问题:

一个简单的例子(两个项目 - Black-Arial-10-Bold):

A simple example (both items - Black-Arial-10-Bold):

 public partial class Form1 : Form
 {
    public Form1()
    {
        InitializeComponent();

        ListBox1.Items.AddRange(new Object[] { "First Item", "Second Item"});
        ListBox1.DrawMode = DrawMode.OwnerDrawFixed;
    }

    private void ListBox1_DrawItem(object sender, DrawItemEventArgs e)
    {
        e.DrawBackground();
        e.Graphics.DrawString(ListBox1.Items[e.Index].ToString(), new Font("Arial", 10, FontStyle.Bold), Brushes.Black, e.Bounds);
        e.DrawFocusRectangle();
    }
 }
