nit: if (!popup_) {

Done.

nit: Please add a brief comment here about the lifetime of this object, since
it's uncommon in Chrome code to see unprotected |new| calls.  When does this
popup actually get registered with the OS to be automatically freed?

[csharp, 2012/08/14 19:06:13]

Comment added, let me know if it needs more details (There are also some notes
in the header definition of popup_)

+    params.can_activate = false;
+    params.transparent = true;
+    params.parent_widget = browser_view->GetWidget();
+    popup_->Init(params);
+    popup_->SetContentsView(this);
+    popup_->Show();
+
+    gfx::Rect client_area;
+    web_contents_->GetContainerBounds(&client_area);
+    popup_->SetBounds(client_area);
+  }
+
+  ResizePopup();
+
+  render_view_host_->AddKeyboardListener(this);
+
+  SetVisible(true);

+
+void AutofillPopupViewViews::HideInternal() {
+  render_view_host_->RemoveKeyboardListener(this);
+
+  SetVisible(false);

+
+void AutofillPopupViewViews::InvalidateRow(size_t row) {
+  // TODO(csharp): invalidate this row.
+}
+
+void AutofillPopupViewViews::ResizePopup() {
+  gfx::Rect popup_bounds = element_bounds();
+  popup_bounds.set_y(popup_bounds.y() + element_bounds().height());

[Ilya Sherman, 2012/08/14 05:12:09]

nit: It's a little weird to use popup_bounds.y() and element_bounds().height(),
since the two are equal before you update the y-coordinate.  I'd just use
popup_bounds for both.

[csharp, 2012/08/14 19:06:13]

Done.
