In previous version (3.5.7), we were able to receive VirtualTree.KeyDown message when hit enter key in the tree (a row or few rows have been selected in the tree before hit the key), but after we upgrade to 3.10.2, we cannot receive KeyDown event on "enter", "f" keys (I am not sure what keys else we cannot receive, for example "a", "b", "c", "d", "e" keys are ok, but "f" not... the most improtant keys for us are "enter" and "f").
Note: we did not change our code, we just upgrade VirtualTree only

The behaviour for the "f" key is not a Virtual Tree issue. I have just checked by adding a KeyDown event handler to the Simple Tree sample project as follows:

Code:

        private void _virtualTree_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.F)
            {
                System.Diagnostics.Trace.WriteLine("Got F");
            }
        }

When the control has focus this duly prints out "Got F" to the output window when you hit the "f" key.

The Enter key handling has changed however. It is processed by the VirtualTree.ProcessEnterKey method and so you won't receive the event in the KeyDown event handler. Normally Virtual Tree uses the Enter key
to manage Cell Editors. If you really need to get this event then you can override the VirtualTree.ProcessEnterKey and return false. This will mean that the KeyDown event will be then raised for the Enter key.
