Thanks Guys.

I thought it over, could it be done with events? I dont really understand events yet.

I thouht that the Listbox of Form1 would subscribe to the state change in the Routers.

Could you please help with that too?

Hi

You can iterate through ListBox row and based on requirement Brush and Graphic objects to color the row. Example code as below:

private void ListBox1_DrawItem(object sender, DrawItemEventArgs e)
{
e.DrawBackground();
Graphics g = e.Graphics;
Brush myBrush = Brushes.Black;
Brush myBrush2 = Brushes.Red;
g.FillRectangle(new SolidBrush(Color.Silver), e.Bounds);
e.Graphics.DrawString(listBox1.Items[e.Index].ToString(), e.Font, myBrush, e.Bounds, StringFormat.GenericDefault);
for (int i = 0; i < listBox1.Items.Count; i++)
{
for (int j = 0; j < existingStudents.Count; j++)
{
if (listBox1.Items[i].ToString().Contains(existingValue[j]))
{
e.Graphics.DrawString(listBox1.Items[i].ToString(),
e.Font, myBrush2, e.Bounds, StringFormat.GenericDefault);
}
}
}
e.DrawFocusRectangle();
}

Hi
Control.Items[3].Attributes.CssStyle.Add("color", "red");

Thanks and regards
