Question

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.

Answer 1

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

Also look at this question on msdn forums:
Question on ListBox items

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();     }  }
