The IEWC Tree View component is useful if you are writing an ASP.NET 1.1 application and need to display a relatively large collapsible hierarchy (tree structure).
During installation (addressed in an earlier blog), a "/webctrl_client" directory is added to your default web site (c:\inetpub\wwwroot\webctrl_client). By default, the treeview component uses this location to reference the client-side scripts for image rendering and click behavior.
If you have a shared server environment with multiple web sites (Win2k Server or Win2k3 server), you have to copy this webctrl_client folder to the home directories of each site using the controls.
Alternatively, you can define a custom location in your web.config. This would allow you to set up a virtual directory and maintain the webctrl_client stuff in a SINGLE PLACE.
Here is close to the syntax to add to your web.config, directly within the section.
<section name="MicrosoftWebControls" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.3300.0,Culture=neutral,PublicKeyToken=b77a5c561934e089"/>
<add key="CommonFiles" value="/iistreeprint.net/webctrl_client/1_0/" />
