Is it possible to format a ComboBox item in C#? For example, how would I make an item bold, change the color of its text, etc.?

推荐答案

您可以执行此操作通过设置 DrawMode 到 OwnerDrawFixed ，这使您可以使用 DrawItem 事件。

You can do this by setting the DrawMode to OwnerDrawFixed which allows you to manually draw the items using the DrawItem event.

comboBox1.DrawMode = DrawMode.OwnerDrawFixed; comboBox1.DrawItem += new DrawItemEventHandler(comboBox1_DrawItem); private void comboBox1_DrawItem(object sender, DrawItemEventArgs e) { Font font = comboBox1.Font; Brush brush = Brushes.Black; string text = comboBox1.Items[e.Index]; if (you want bold) font = new Font(font, FontStyle.Bold); if (you want green) brush = Brushes.Green; e.Graphics.DrawString(text, font, brush, e.Bounds); }
