Controls not processing Keyboard events

[Guest]

Hi Al

I am a new to developing CF applications and am trying to port a regular .NET application to CF. From what I have read it looks like individual controls in a form should get Keyboard events, however this does not seem to work with any of my controls

e.g. I have a combobox called cmbTrainID and I have an event handler for it as follows
Private Sub cmbTrainID_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles cmbTrainID.KeyDow

-- application specific cod

End Su

However when I press the down arrow on the combobox(when it has focus), the event if not fired. Do I need to do anything additional for this event to be handled

(Sorry for asking such a stupid question, but I did not do anything more than this with the .NET app

Highly appreciate your inpu

Thank

Balu

Many of the intrinsic controls (Textbox, Label, Combobox etc) do not fire
the whole range of events supported in API. While painting events generally
cannot be intercepted at all, the keyboard and mouse events are possible to
intercept via corresponding windows messages (WM_CHAR, WM_LBUTTONDOWN...)
using OpenNETCF ApplicationEx class
