Problem - KeyDown even does not occur for UserControl in C#

Question

Hello.

I am working on KeyDown event control in C#.

Of course, it works in main.form, but not in Form.SplitterPanel.Panel1.UserControl.

I think "focus" and "keyPreview setting" is not a problem since KeyUp event method occurs with no problem.

I tried to solve this problem with many solutions through the Internet, but nothing could help.

I do not know key event occur for "KeyUp", but not for "KeyDown" and "KeyPress".

What is the big difference between them.

Please help me.
