+It is nothing to do with UserControl. It looks rather DockStyle.Fill
+and BringToFront() matter.
+
+Minimized repro code:
+
+using System;
+using System.Drawing;
+using System.Windows.Forms;
+
+public class Form1 : Form
+{
+        Button button1;
+        Button button2;
+        System.Windows.Forms.Panel panel1;
+        Label f1;
+        Label f2;
+
+        static void Main()
+        {
+                Application.Run(new Form1());
+        }
+
+        public Form1()
+        {
+                button1 = new Button();
+                button2 = new Button();
+                panel1 = new Panel();
+                panel1.Dock = DockStyle.Top;
+                button1.Location = new Point(32, 8);
+                button1.Text = "Load page 1";
+                button1.Click += new EventHandler(this.button1_Click);
+                button2.Location = new Point(160, 8);
+                button2.Text = "Load page 2";
+                button2.Click += new EventHandler(this.button2_Click);
+                Controls.Add(this.button1);
+                Controls.Add(this.button2);
+                Controls.Add(this.panel1);
+
+                f1 = new Label();
+                f1.Text = "Panel 1";
+                f1.Dock = DockStyle.Fill;
+                Controls.Add(f1);
+                f2 = new Label();
+                f2.Text = "Panel 2";
+                f2.Dock = DockStyle.Fill;
+                Controls.Add(f2);
+        }
+
+        void button1_Click(object sender, System.EventArgs e)
+        {
+                f1.BringToFront();
+        }
+
+        void button2_Click(object sender, System.EventArgs e)
+        {
+                f2.BringToFront();
+        }
+}
+
+Comment out f1.Dock = DockStyle.Fill (or f2) and it will work (control
+will be hidden, but keyboard control is still possible).
