Send input to TextBox programatically

I everybody,

I'm trying, when a control receives an OnPreviewKeyDown event, to
send this KeyStroke to another control (control in question varies from
a case to another)... By just sending a PreviewKeyDown/KeyDown
RoutedEvent to the control, it works fine (for some controls), however,
in the case of a TextBox, it fails miserably...

I tried passing by the InputManager...
(InputManager.Current.ProcessInput()... )

Has anybody succeeded in doing something like this?

Or otherwise, is there any other Text input control which would suit
my needs?

Thanks.

There's no way to simulate input in Avalon other than calling Win32's
SendInput method. Raising a KeyDown event is an approximation networks in
some cases, but as you've noticed, it doesn't work with TextBox because it
doesn't generate TextInput events or update the state of the Keyboard class
correctly.

Perhaps there's another way of accomplishing what you're trying to do -- why
do you want to forward keyboard input to another control?
