I\'m making an example for someone who hasn\'t yet realized that controls like ListBox don\'t have to contain strings; he had been storing formatted strings and

If you use a draw method like:

private void listBox1_DrawItem(object sender, DrawItemEventArgs e)
{
    e.DrawBackground();
    e.DrawFocusRectangle();

    Sensor toBeDrawn = (listBox1.Items[e.Index] as Sensor);
    e.Graphics.FillRectangle(new SolidBrush(toBeDrawn.ItemColor), e.Bounds);
    e.Graphics.DrawString(toBeDrawn.sensorName, new Font(FontFamily.GenericSansSerif, 14, FontStyle.Bold), new SolidBrush(Color.White),e.Bounds);
}

Sensor is my class.

So if I change the class Color somewhere, you can simply update it as:

int temp = listBoxName.SelectedIndex;
listBoxName.SelectedIndex = -1;
listBoxName.SelectedIndex = temp;

And the Color will update, just another solution :)
