+Summary: DataGrid: OnLeave() is incorrectly invoked when it gets focus
+
+There is a focus handling bug in DataGrid. Build the example below, run,
+and click a grid cell.
+
+using System;
+using System.Data;
+using System.Drawing;
+using System.Windows.Forms;
+
+public class Test : Form
+{
+        public static void Main ()
+        {
+                Application.Run (new Test ());
+        }
+
+        public Test ()
+        {
+                DataGrid b = new DataGrid ();
+                b.Dock = DockStyle.Top;
+                DataTable table = new DataTable ("test");
+                table.Columns.Add ("col1");
+                table.Columns.Add ("col2");
+                table.Rows.Add (new object [] {"foo", "bar"});
+                b.DataSource = table;
+                b.Leave += delegate (object o, EventArgs e) {
+                        Console.WriteLine ("+++ Leave +++");
+                };
+                CheckBox c = new CheckBox ();
+                c.Location = new Point (100, 100);
+                Controls.Add (b);
+                Controls.Add (c);
+        }
+}
+
+
+Actual Results:
+
+It prints "+++ Leave +++" whereas it actually gets focus.
+
+Expected Results:
+
+no Leave event.
+
+How often does this happen? 
+
+consistently.
+
+Additional Information:
+
+If I understand correctly it kinda blocks bug #78363.
