Telerik RadControls replace IE Web Controls in Web Forms applications – PB Docs 2022

PowerBuilder 11.2 uses Telerik RadControls for menus, toolbars,
and other controls in Web Forms applications by default. Although not
recommended, you can use IE Web Controls instead of the RadControls, but
you must change the PBWebControlSource global property for your
application and install the IE Web Controls on the server.

If you must use IE Web Controls, you need to download IE Web
Controls from the Microsoft website and install the controls on the Web
server. After you install the controls, you must set the
PBWebControlSource selection to “IE”, either on the Configuration tab of
the Project painter before you deploy your application, or in the
Web.config file after you deploy your application.
