Hello,

I created a new C# Windows Application in Visual Studio 2008, and added a Panel (from the Toolbox) to the Form.
But, I don't see the MouseWheel event of the Panel.

Panel derives from Control, which does has the MouseWheel event.
So why Panel does not have the MouseWheel event ?

Thanks !

That is because Panel is used as a container and it does not gets focussed. Only the controls inside it get focus. So, if you have a Panel in a form and do a MouseWheel on panel, form's event will be fired and not the Panels.

In case any of the control inside panel has focus, it's mouse wheel event will be fired.
