c# - MouseEnter and MouseLeave events from a Panel and its child controls

I have a Panel that contains child controls.

If I handle the Panel's MouseEnter and MouseLeave events, and its child's MouseEnter and MouseLeave events, the events are raised in this order:

Panel.MouseEnter
Panel.MouseLeave
Child1.MouseEnter
Child1.MouseLeave
Panel.MouseEnter
Panel.MouseLeave

But I need the following order:

Panel.MouseEnter
Child1.MouseEnter
Child1.MouseLeave
Panel.MouseLeave

Is that possible?

If you dont mind creating a usercontrol(derived from the panel or other parent container you wish), Override your parent's OnMouseLeave method to look like the following..

protected override void OnMouseLeave(EventArgs e)
{

    if(this.ClientRectangle.Contains(this.PointToClient(Control.MousePosition)))
         return;
    else
    {
        base.OnMouseLeave(e);
    }
}

Then, the event raising will be in the required order.
