+Summary: ListView.OnItemActivate does not work
+
+Description of Problem:
+OnItemActivate does not appear to be called in a derived class. 
+
+Steps to reproduce the problem:
+1. Compile and run the following program.
+using System;
+using System.Windows.Forms;
+class TestForm : Form {
+    static void Main() {
+        Application.Run(new TestForm());
+    }
+    public TestForm() {
+        MyListView listView = new MyListView();
+        listView.Items.Add("Test");
+        Controls.Add(listView);
+    }
+}
+class MyListView : ListView {
+    protected override void OnItemActivate(EventArgs e) {
+        MessageBox.Show(string.Empty);
+    }
+}
+2. Double click on the item.
+
+Actual Results:
+Nothing happens.
+
+Expected Results:
+A message box appears.
+
+How often does this happen? 
+Always.
+
+Additional Information:
+Strangely, handling ItemActivate seems to work, like in the following 
+example.
+using System;
+using System.Windows.Forms;
+class TestForm : Form {
+    static void Main() {
+        Application.Run(new TestForm());
+    }
+    public TestForm() {
+        ListView listView = new ListView();
+        listView.Items.Add("Test");
+        Controls.Add(listView);
+        listView.ItemActivate += new EventHandler(listView_ItemActivate);
+    }
+
+    void listView_ItemActivate(object sender, EventArgs e) {
+        MessageBox.Show(string.Empty);
+    }
+}
