c# - prevent mousewheel scrolling in panel

问题

I want to prevent scrolling with the mousewheel in a panel with a scrollbar, how can ido this?

I have seen this suggested, but it's not working:

panel.MouseWheel += new MouseEventHandler(MouseWheel);

void MouseWheel(object sender, MouseEventArgs e) {
  ((HandledMouseEventArgs)e).Handled = true;
}

回答1:

Try inheriting your own Panel and just comment out the OnMouseWheel call:

public class WheelessPanel : Panel {
  protected override void OnMouseWheel(MouseEventArgs e) {
    // base.OnMouseWheel(e);
  }
}

回答2:

If you provide a user with a scrollable control, why would you then prevent them from scrolling it? If you don't want them to scroll, don't give them scroll bars.

If I came across a UI like that I would dislike it and only use it if I absolutely had to.
