Color in ComboBox Item

Example:

First Create a CustomComboBox control, with this C# code:

using System;
using System.Windows.Forms;
using System.Drawing;
namespace TyroDeveloperDLL
{
    public class ComboBoxCustom : ComboBox
    {
        public ComboBoxCustom()
        {
            this.DrawMode = System.Windows.Forms.DrawMode.OwnerDrawFixed;
        }
        protected override void OnDrawItem(DrawItemEventArgs e)
        {
            base.OnDrawItem(e);
            if (e.Index < 0) { return; }
            e.DrawBackground();
            ComboBoxItem item = (ComboBoxItem)this.Items[e.Index];
            Brush brush = new SolidBrush(item.ForeColor);
            if ((e.State & DrawItemState.Selected) == DrawItemState.Selected)
            { brush = Brushes.Yellow; }
            e.Graphics.DrawString(item.Text, 
                this.Font, brush, e.Bounds.X, e.Bounds.Y);
        }
        object selectedValue = null;
        public new Object SelectedValue
        {
            get
            {
                object ret = null;
                if (this.SelectedIndex >= 0) { 
                    ret = ((ComboBoxItem)this.SelectedItem).Value; 
                }
                return ret;
            }
            set { selectedValue = value; }
        }
        string selectedText = "";
        public new String SelectedText
        {
            get
            {
                return ((ComboBoxItem)this.SelectedItem).Text;
            }
            set { selectedText = value; }
        }
    }
    public class ComboBoxItem
    {
        public ComboBoxItem() { }

        public ComboBoxItem(string pText, object pValue)
        {
            text = pText; val = pValue;
        }

        public ComboBoxItem(string pText, object pValue, Color pColor)
        {
            text = pText; val = pValue; foreColor = pColor;
        }

        string text = "";
        public string Text
        {
            get { return text; }
            set { text = value; }
        }

        object val;
        public object Value
        {
            get { return val; }
            set { val = value; }
        }

        Color foreColor = Color.Black;
        public Color ForeColor
        {
            get { return foreColor; }
            set { foreColor = value; }
        }

        public override string ToString()
        {
            return text;
        }
    }
}

To add the ComboBox Items:

comboBoxCustom1.Items.Add(new ComboBoxItem("México","0",Color.Green));
comboBoxCustom1.Items.Add(new ComboBoxItem("USA", "1", Color.Blue));
comboBoxCustom1.Items.Add(new ComboBoxItem("China", "2", Color.Red));

Too is possible add items from a database with a DataReader:

OleDbConnection cnn = new OleDbConnection(Class.clsMain.CnnStr);
try
{
    string SQL = "SELECT ID_SUBDIVISION, SUBDIVISION "+
        " FROM SUBDIVISION WHERE [ENABLED]=TRUE";

    cnn.Open();
    OleDbCommand cmd = new OleDbCommand();
    cmd.Connection = cnn;
    cmd.CommandText = SQL;
    OleDbDataReader dr = cmd.ExecuteReader();
    while (dr.Read()) {
        cbo.Items.Add(new ComboBoxItem(dr["SUBDIVISION"].ToString(), 
            dr["ID_SUBDIVISION"], Color.Blue));//Set your color here
    }
    dr.Close();
    cbo.SelectedIndex = 0;
}
catch (Exception ex) { throw (ex); }
finally { cnn.Close(); }
