I pushed my web site to a remote server for testing and after setting up IIS and the site, everything looked good, except for the fact that alll RAD controls were missing (not visible) on the pages.

I figured it was possibly a dll registration issue and tried to register the Telerik.Web.UI.dll manually and got the following error:

"C:\Inetput\wwwroot\2008\Bin\Telerik.Web.UI.dll was loaded, but the DllRegisterServer entry point was not found.
This file can not be registered."

Any help would be appreciated.

Thanks,

Rod

I experienced the exact same problem after upgrading to the latest version.  Not good indeed.  Hopefully they tested before deploying?  :)

Hello everyone,

Please accept our sincere appologies for the problem. We were able to reproduce it, and have prepared a workaround in the following sticky forum thread

http://www.telerik.com/community/forums/aspnet-ajax/splitter/problem-with-visibleduringinit-false.aspx


The omission is clearly on our end, and I am deeply sorry for the frustration caused. Perhaps shedding more light on the origins of the issue is needed. By default VisibleDuringInit property is set to true.When it is set to false, the splitter renders invisible and is then shown once it completes calculating its size, and the size of its child panes. The way this was done has been changed from Q2 to Q3, and hence the introduction
of the problem. The change was made because of reports that elements, whose visibilitty is explicitly set to style=visibility:visible, are visible during the splitter intialization process, which was, of course, undesireable.

So, a new mechanism for hiding the splitter and its contents was devised. However, due to a bug in Internet Explorer rendering engine, the new mechanism turned out to expose the problem you encountered. If you examine your pages in any other supported browser, e.g. FireFox or Safari, you will notice that your controls render fine and are visible.

The problem "slipped under the radar" of our QAs for the following reasons:

- It is not manifested always, even in IE.
- The property must be set explicitly to encounter the problem, as the default property value is different.
- The problem only occurs in IE

and most important - the problem could not (and cannot) be detected by our our automated tests - since it is a purely visual (that is, everything is "technically" visible - even for IE - you can use a tool such as IEDevToolbar to verify that).

As a result, we are in the process of implementing additional procedures related to testing RadSplitter to ensure a problem of this kind does not occur again.

The sticky thread provides a workaround, that we believe is fairly easy - what you need to do is add 6 lines of javascript to your RadSplitter page. In addition to this, however, should you need a fixed Telerik.Web.UI build,
please contact us with a support message, and we will send you a custom build DLL as well.
