I have a web application running on IIS default web site with vitural
directory and so. This is for the development site. Also, I have a
production web application running on the same IIS but on its own web
site. This version is for the internet users. They are the same
applications because I copy all files from the default web site and
paste them in the production web site. However, they behave
differently. The applications have a treeview control. I set
Autopostback = True and smatrnavation = true because I want
SelectedIndexChanged event to be fired when I select different tree
node and prevent the tree node collapsing. When I run the application
from IIS default web site, it works perfectly. I mean there is no
flickering and no delay when I select different tree nodes. However,
when I run the production version which run from its own web site,
there seems to be a 2-sec dely every time different tree node is
selected. I see a blank page for 2 sec every time. Is something
wrong with my treeview control setting or web site configuration? How
these two web sites are different?
