c# custom Panel

Question

I'm trying to create a custom panel containing some buttons and labels. The problem is that I can't set displaying order properly in code. I have something like this:

 public partial class Pallete1 : Panel
    {
        private Label lblAutomatic;       
        private Label lbldivider1;

        public Pallete1():base()
        {
            InitializeComponent();
            this.lblAutomatic = new Label();
            this.lbldivider1 = new Label();

            this.lblAutomatic.Size = new Size(182,21);
            this.lblAutomatic.Location = new Point(0, 0);
            this.lblAutomatic.ForeColor = Color.FromArgb(0, 0, 64);
            this.lblAutomatic.TextAlign = ContentAlignment.MiddleCenter;
            this.lblAutomatic.Text = "Automatycznie";
            this.lblAutomatic.Font = new Font("Microsoft Sans Serif", 8);

            this.lbldivider1.Size = new Size(2,22);
            this.lbldivider1.Location = new Point(26, 0);
            this.lbldivider1.ForeColor = SystemColors.ControlText;
            this.lbldivider1.BackColor = SystemColors.ButtonHighlight;
            this.lbldivider1.BorderStyle = BorderStyle.Fixed3D;


            this.Size = new Size(182, 184);
            this.BackColor = SystemColors.ButtonHighlight;
            this.BorderStyle = BorderStyle.FixedSingle;
            this.Controls.AddRange(new Control[]{this.lblAutomatic,this.lbldivider1});

        }

I would like lbldivider1 to be on the top of lblAutomatic. When I add this item to some WinForm projects, this second label is only seen when I drag my custom panel from one place to another. However it's not seen in the designer when it's not moving and also when I'm launching the application.

How can I fix it?

I've tried this one already, but unfortunately it doesn't work for me. — Paweł Poręba, Oct 30 '15 at 11:21
What doesn't work for you? I've tried your posted code and it does work (I see a vertical line) — Ivan Stoev, Oct 30 '15 at 11:29
What's so special in your project? I've opened a new WinForms project, pasted your code, added what @TaW said at the end of your method above, buiid, drop on a form - and it's there, in both design and run time — Ivan Stoev, Oct 30 '15 at 11:37
Well, I did the same and I can't see the vertical line. As I've said, I see it only while dragging the control in designer. — Paweł Poręba, Oct 30 '15 at 11:39
Good luck then. In order to get help, you must provide a code that we can run and duplicate the problem. — Ivan Stoev, Oct 30 '15 at 11:46

If you want to set label's position over second one, use ZOrder property, in case of putting one under another, you would choose TableLayoutPanel or FlowLayoutPanel.

Maybe add some examples to show the OP how to do this? Without writing the code for them of course. – TheLethalCoder Oct 30 '15 at 11:12

I don't know `Windows.Forms.Control` having a property called `ZOrder` – Ivan Stoev Oct 30 '15 at 11:15
Indeed, there's no `ZOrder` property. – Paweł Poręba Oct 30 '15 at 11:27
No such property `ZOrder` in WinForms https://msdn.microsoft.com/en-us/library/system.windows.forms.control(v=vs.110).aspx – Oct 30 '15 at 11:29

Ok, if you don't have some hidden code, any of the following should work:

(A)

this.Controls.AddRange(new Control[]{this.lblAutomatic,this.lbldivider1});
this.lbldivider1.BringToFront();

(B)

this.Controls.AddRange(new Control[]{this.lblAutomatic,this.lbldivider1});
this.lblAutomatic.SendToBack();

(C) Simply swap when adding (make sure lbldivider1 goes first in z order)

this.Controls.AddRange(new Control[]{this.lbldivider1, this.lblAutomatic});

thanks! I appreciate this feedback a lot. Of course I was doing a stupid thing, I mean I've added `this.lbldivider1.BringToFront()` before adding it to panel's list of controls. Really thanks, sometimes such stupid mistakes steal lot of time:) – Paweł Poręba Oct 30 '15 at 16:34

As per this question it seems ZOrder is a VB property not available in C#, however there is a SetChildIndex on the parent's Controls collection.

Try

this.Controls.SetChildIndex(lblAutomatic, 1);
this.Controls.SetChildIndex(lbldivider1, 2);
