Keyboard Events (keypress and keydown) in winform and how to handle non-responding Keyboard Events

The keydown event is used to process the function key: F1 F2 F3...
The keypress event is used to process characters such as a B c... 1 2 3...
Note: When processing this event, you must first set the keypreview of the form to true ;(Note that if this option is not set, most of the reasons for Keyboard Events Not responding)

Keypress event example:
Private void formmain_keypress (Object sender, keypresseventargs E)
{
If (E. keychar. tostring () = keys. A. tostring ())
{
This. tsmigoto_click (sender, e); // execute the event after the conditions are met
}
}

Example of a keydown event:
Private void formmain_keydown (Object sender, keyeventargs E)
{
If (E. keydata = keys. F8)
{
This. tsmigoto_click (sender, e); // execute the event after the conditions are met
}
}
