  You can do this by creating owner drawn combo box:

  public class XComboBox : ComboBox

  {

  /// <summary>

  /// Intializes a new instance of the XComboBox class

  /// </summary>

  public XComboBox()

  {

  DrawMode = DrawMode.OwnerDrawFixed;

  }

  protected override void OnDrawItem(DrawItemEventArgs e)

  {

  base.OnDrawItem(e);

  if (e.Index > -1 && e.Index < Items.Count)

  {

  // If <some condition>, change the backcolor

  if (Items[e.Index].ToString().Contains("1"))

  e.Graphics.FillRectangle(Brushes.Blue, e.Bounds);

  else

  e.DrawBackground();

  using (Brush textBrush = new SolidBrush(e.ForeColor))

  {

  e.Graphics.DrawString(Items[e.Index].ToString(), this.Font, textBrush, e.Bounds);

  }

  e.DrawFocusRectangle();

  }

  }

  }

  The following example paints the background of items that has 1 in them in blue,
