C# - Reordering controls by z-index in Panel

Question

I have a Panel with a PictureBox with Dock = DockStyle.Fill. I need to dynamically add controls to the Panel, but they must stay above the PictureBox.

This is easy within the Designer, but when I do this programmatically, neither SetChildIndex(), BringToFront() or SendToBack() work.

I have to use PictureBox, I can't just set Panel.BackgroundImage because it's glitchy.

Answer 1

I fount this to be an issue with the order of the controls in the panel in the design.cs

Remove the controls from the panel and add them in the correct order.

        this.panel1.Controls.Add(this.pictureBox1);
        this.panel1.Controls.Add(this.button1);
        this.panel1.Location = new System.Drawing.Point(12, 12);
        this.panel1.Name = "panel1";
        this.panel1.Size = new System.Drawing.Size(260, 238);
        this.panel1.TabIndex = 0;

        this.panel1.Controls.Add(this.button1);
        this.panel1.Controls.Add(this.pictureBox1);
        this.panel1.Location = new System.Drawing.Point(12, 12);
        this.panel1.Name = "panel1";
        this.panel1.Size = new System.Drawing.Size(260, 238);
        this.panel1.TabIndex = 0;
