Hi Wael,
Did you want extend the Panel control or the whole IE window? If it is the
IE window, the scoll bar will appear automatically, and we don't need to
set it. If It is the Panel control, we need to set it with a Css Class and
made it scrollable.
Additionally, for ASP.NET related issue, you can send to
Microsoft.public.dotnet.framework.aspnet. You may find more useful
information there.
