ListBox is rendered last so z-index has no effect.
Can a use any (html) trick to get the object attach to the DragPanelExtender (asp:panel) moving over the ListBox?

My reading of thez-index documentation makes me think it would help here - you're saying it doesn't?
no z-index fails
On IE (at least) ListBox, TextBox, and ComboBox are actual windows controls placed by the browser. Since they are separate HWNDs ordered above the browsers rendering surface HWND< they can't be z-ordered under other elements, unfortuntately.
I am running into this right now. The DragPanelExtender is pretty much useless unless you don't have any controls with Hwnds on your page (which is very rare for me.) Granted I could leave it, but it does not look professional at all.
The frustrating thing is that the PopupControlExtender DOES get layered above all other controls. So I think it is an opportunity for the Atlas team to change the DragPanelExtender to have whatever it is the PopupControlExtender has that allows it to be on top.
If I come up with a solution, I will post it. I think there should be a way around this if the PopupControlExtender is able to show HTML content on top of an asp:DropDownList.
can i use css adapters to make z-index to work for DropDownList ...
I found another page have some hints to doing so, I think it should also implement to Modal Popup
