mouseover for child controls of a panel in vb.net

Hello guys,

I am here with another problem

I have a panel called PanelItems in a form
I have many controls like textbox and label on it

In mouseover event of panel I am incremanting the size of the panel
and in mouseleave event of panel I am decrementing the size of the panel

Now here is the problem
When the mouse cursor goes over any control on the panel then also the mouseover event of panel does not fire.
as well as when the size of the panel is big then if we move the cursor over any control on the panel then mouseleave event of the panel is fired

I want some suggesstion from you guys

Thanks
