I have embedded the vt control into a Panel and added event handlers for KeyDown, KeyUp, and KeyPress, even provided a WndProc()

protected override void WndProc(ref Message msg)

It seems that Control keys cannot be trapped or sent via telnet connection.

As my Vt component is embedded with a Form, the control keys are being handled by the Form and trated as MenuItem accelarators instaed of being trapped by the Vt component (as it has focus) and then sent via Telnet?

Is there something else I need to do to handle this?

I tried it with a TextBox and discovered that the only event that fires is the KeyUp event when a Shortcut key combo is pressed.

I have written up an issue to investigate why our KeyUp event does not fire and also to see if we need to change the behavior of KeyDown and Keypress.

The issue is #2636. If you have questions about the status of the issue, please contact Dave Harry (sales@dart.com)

Duplicate of TTWeb #2388. The KeyUp event is not used; use the KeyDown and KeyPress events
