comboBox控件下拉选项中添加图片

comboBox下拉选项中添加图片

1、将需要添加的图片加入到imageList中
2、循环图片清单，将图片绘入comboBox中，代码如下：

		private void FormMain_Load(object sender, EventArgs e)
            foreach (string key in imageList1.Images.Keys)
            {
                comboBox1.Items.Add(key);
            }
            comboBox1.DrawMode = DrawMode.OwnerDrawFixed;
            comboBox1.DropDownStyle = ComboBoxStyle.DropDownList;
            comboBox1.DrawItem += CbbImages_DrawItem;
            comboBox1.SelectedIndex = 0;
		}
		
        private void CbbImages_DrawItem(object sender, DrawItemEventArgs e)
        {
            e.DrawBackground();
            e.Graphics.DrawImage(imageList1.Images[e.Index], 5, e.Bounds.Y, 40, 40);
            e.Graphics.DrawString(comboBox1.Items[e.Index].ToString(), new Font("宋体", 16), new SolidBrush(Color.Red), 45, e.Bounds.Y + 1);
        }
