How to prevent user input from entering keyboard form (arrow keys) in C #

my usercontrol contains other controls that you can select, I would like to implement a way to navigate through the children using the arrow keys

The problem is that the parent controll intercepts the arrow keys and uses it to scroll its view, which I want to avoid. I want to decide to manage the contents of the control myself.

How can I control the standard behavior caused by the arrow keys?

Thanks in advance MTH
