How to set Foreground Color in a ListBox single element?
- by user1038056
I'm doing a game. I have a list of users (nicks):
List<string> users;
This list is used to show to the users on a ListBox, call listaJogadores.
public delegate void actualizaPlayersCallback(List<string> users);
public void actualizaPlayers(List<string> users)
{
listaJogadores.BeginInvoke(new actualizaPlayersCallback(this.actualizarListaPlayers), new object[] { users });
}
public void actualizarListaPlayers(List<string> users)
{
listaJogadores.Items.Clear();
for (int i = 0; i < users.Count; i++)
{
listaJogadores.Items.Add(users.ElementAt(i));
}
}
When a user is playing, then it have is nick on the list of games:
List<Game> games;
What I want is when a player enter in a game, the color of is nick show in listaJogadores, must be Red!
When I have only one player in a game, everything is ok, all the players see the nick of that player in red, but when another player go to a game, then I get an ArgumentOutOfRangeException in the instruction string nick = tmp.players.ElementAt(i).getNick();
This is my code... Give me some ideas/help please! I think that the problem is the for(), but how can I manipulate an entire list without doing a loop?
listaJogadores.DrawMode = DrawMode.OwnerDrawFixed;
private void listaJogadores_DrawItem(object sender, DrawItemEventArgs e)
{
e.DrawBackground();
Brush textBrush = SystemBrushes.ControlText;
Font drawFont = e.Font;
for (int i = 0; i < games.Count; i++)
{
Game tmp;
tmp = games.ElementAt(i);
for (int j = 0; j < tmp.players.Count; j++)
{
string nick = tmp.players.ElementAt(i).getNick();
if (listaJogadores.Items[e.Index].ToString() == nick)
{
textBrush = Brushes.Red;//RED....
if ((e.State & DrawItemState.Selected) > 0)
drawFont = new Font(drawFont.FontFamily, drawFont.Size, FontStyle.Bold);
}
else if ((e.State & DrawItemState.Selected) > 0)
{
textBrush = SystemBrushes.HighlightText;
}
}
}
e.Graphics.DrawString(listaJogadores.Items[e.Index].ToString(), drawFont, textBrush, e.Bounds);
}
