How do I place card so each added card overlap in the way I want

[Tony Johansson]

Hello

Here is some code that place a user control called CardGUI in another user
control named PlayerGUI.
Assume width for the CardGUI is 100. The first card is placed at xPos=0 and
y=0.
Now when I place the second card I set xPos = 50 and y = 0.
The problem is that I want the second card to overlap the first so only the
left part of the first card is shown.
I thought this code did this but here only the right part the second card
that is shown.

private void InitialDeal()
{
Control[] ctrl = this.pnlPlayers.Controls.Find(PlayerGUI, false);

for (int cardNr = 0; cardNr < StartDeal; cardNr++)
{
for (int playerNr = 0; playerNr < ctrl.Length; playerNr++)
{
Card card = gm.GetPlayerCard(playerNr, cardNr);
for (int i = 0; i < pnlPlayers.Controls.Count; i++)
{
PlayerGUI pg = ctrl as PlayerGUI;
if (pg.PlayerName == gm.Players[playerNr].Name)
{
string imagePath =
Path.Combine(Environment.CurrentDirectory, @"..\..\Images\" + card.Suit+
".ico");
CardGUI cg = new CardGUI(imagePath,card.RankSymbol());

int xPos = (cardNr % 2) * cg.Width/2;
cg.Location = new Point(xPos, 0);
pg.AddCard(cg);
break;
}
}
}
}
}

Google "z-order". In .NET, BringToFront() and SendToBack() can help you
manage this.

This BringToFront on my user control CardGUI does not bring that control to
front it is still in the back.
I have a panel that I put these user control in and I always want the last
added control to be in the front.
I have read the docs and it doesn't say any strange about this. It says
"The control is moved to the front of the z-order. If the control is a child
of another control, the child control is moved to the front of the z-order.
BringToFront does not make a control a top-level control, and it does not
raise the Paint event."
I don't get any kind of error it just don't do what I have told it to do
which is bring the control in front.

Have I missed something here ?

Definitely. But since you haven't bothered to post a concise-but-complete
code example that reliably reproduces the problem, well.you know the rest.

Here is complete example where I use Button and it doesn't work as expected.
As you can see in the code I first put one button in the panel with a text
First and then
I put a second button in the panel with a text Second. This second Button is
positioned a litte bit to the right
from the first button. I use BringTofront to make the last button the
topmost but instead it will be put under the first button so the first
button is always the topmost
Is this perhaps a bug because it doesn't work as it should ?

I have only glanced at this, but I'm virtually positive that your call to
BringToFront() is useless as-is. The button as not been given a parent yet;
this doesn't happen until you call panel1.Controls.Add(). BringToFront()
only works with sibling controls, i.e., controls with the same parent. So if
the button has no parent, what controls is it supposed to be brought to the
front of?

Yes you are right I just move this row
btn.BringToFront();
after this row
panel1.Controls.Add(btn);
and now it works.

Many thanks
