+Summary: UserControl does not pass focus to next control
+
+Once UserControl gets focus, it handles tab key to iterate focus loop only
+inside the control itself and does not pass it to the next control.
+
+The repro code below is simplified PropertyGridTextBox:
+
+using System;
+using System.Drawing;
+using System.Windows.Forms;
+
+class PropertyGridTextBox : UserControl {
+        TextBox textbox;
+        Button dialog_button;
+
+        public PropertyGridTextBox() {
+                dialog_button = new Button();
+                textbox = new TextBox();
+
+                dialog_button.Dock = DockStyle.Right;
+                textbox.Dock = DockStyle.Fill;
+                Controls.Add(textbox);
+                Controls.Add(dialog_button);
+        }
+}
+
+class Test : Form
+{
+        public static void Main ()
+        {
+                Application.Run (new Test ());
+        }
+
+        public Test ()
+        {
+                PropertyGridTextBox tb = new PropertyGridTextBox ();
+                tb.Dock = DockStyle.Top;
+                Controls.Add (tb);
+                Button b = new Button ();
+                b.Dock = DockStyle.Bottom;
+                Controls.Add (b);
+        }
+}
+
+Press tab key around.
+
+Actual Results:
+
+It never passes focus to the button at the bottom of the form.
+
+Expected Results:
+
+It should pass focus to the button.
+
+Additional Information:
+
+It blocks correct PropertyGrid keyboard navigation implementation.
